About this Manual This manual provides detailed instructions for setup, operation and maintenance of the 2020ppbPRO Portable Photoionization Monitor. Before unpacking the instrument, please read Warnings and Safety Practices on pages 4 and 5. This section describes possible hazards that might injure the user, damage the instrument or compromise its operation. Some general safety information is also provided.
Warnings and Safety Practices Please read the Notices and Warnings section of this user’s manual before operating the 2020ppbPRO. Approved Models of the 2020ppbPRO This manual provides operational information for all models of the 2020ppbPRO. The 2020ppbPRO is intrinsically safe and approved for use in hazardous locations. Refer to the Notices and Warnings section of this manual for details of each approval.
2020ppbPRO Overview Figure 1. The 2020ppbPRO Instrument The 2020ppbPRO measures the concentration of airborne gases and vapors that can be ionized by a photoionization detector. The 2020ppbPRO automatically displays and can record these concentrations. The 2020ppbPRO does not distinguish between individual compounds. The reading displayed represents the total concentration of all photoionizable chemicals present in the sample. The 2020ppbPRO displays concentrations in units of ppb as well as ppm and Mg/M3.
In Tag mode operation, the 2020ppbPRO prompts you to locate a site and then to record a background and sample readings for the site. You can record up to 12,000 manual entries. There is no averaging of data in Tag mode. Recorded data can be reviewed on the display or downloaded to a computer. Data are recorded by date and time. The 2020ppbPRO has 5 keys for instrument operation. The keys are used to set up and calibrate the 2020ppbPRO.
A standard of isobutylene at a known concentration may be used for setting the sensitivity. If the 2020ppbPRO is calibrated with isobutylene, it displays concentrations in units equivalent to ppm of isobutylene. If isobutylene were the only photoionizable chemical in the sample, then the 2020ppbPRO would display its concentration directly. The 2020ppbPRO responds more or less readily to other chemicals than it does to isobutylene.
ionized molecules in the detector cell. An electrometer circuit converts the current to a voltage which is then fed to the microprocessor. The UV lamp is operated by a high voltage lamp driver circuit which delivers high voltage energy to the lamp through plates in the lamp holder. The lamp driver power supply is controlled by the microprocessor based on a feedback signal from a light sensor on the driver circuit board. Unpacking Instrument Remove the 2020ppbPRO from its shipping box.
4. If compound threshold limit values (TLVs) are exceeded, you should use a gas bag for sampling and calibration. To determine the TLV of the compounds contained in the calibration gas, refer to the Material Safety Data Sheet (MSDS) supplied with your calibration gas cylinder. If you will be using a gas bag for calibration, see Calibration Using a Gas Bag on page 63 for instructions. Field Operation For field operation, the 2020PRO series Field Kit (Part No. MX750080) is available.
Using the 2020ppbPRO ISP-074-576-P1D 3 37
Battery Charging Before beginning operation of the 2020ppbPRO, the battery pack must be charged. You can also remove the battery pack and replace it with a fully charged spare battery pack (Part No. MX700010 or MX700011). NOTE: You must use the 220 V battery charger (Part No. MX396013) in order to comply with the requirements of the applicable Council Directives. Removing and Replacing the Battery Pack NOTE: Do not remove or recharge the battery pack in a hazardous location. To remove the battery pack: 1.
Charging the Battery Pack NOTE: Only use the AC adapter specified for use with the 2020ppbPRO. Using another AC adapter will result in damage to the battery pack, the 2020ppbPRO or the adapter itself. To charge the battery pack: 1. Plug the AC adapter into the jack located on the bottom of the 2020ppbPRO. 2. Plug the AC adapter into an AC outlet. If you are using the European AC adapter, ensure the correct plug is installed on the line cord .
Leaving the AC adapter connected to the 2020ppbPRO will not harm the battery or the AC adapter in any way. If the 2020ppbPRO is to be left unused for an extended period of time, leave it connected to the AC adapter so that the battery will be fully charged and ready for operation. On average a fully charged battery pack will provide 6 hours of continuous operation. Battery life is shorter if the instrument is turned off and then on again repeatedly, or if the backlighting is turned on.
Figure 5. The 2020ppbPRO Display The display reports instantaneous concentration at all times when the pump is on. In Interval mode, the display will report instantaneous concentrations as well as PEAK, STEL or TWA.

Calibrating the 2020ppbPRO ISP-074-576-P1D 4 59
Calibration Introduction The 2020ppbPRO must be calibrated in order to display concentration in ppm units equivalent to the calibration gas. First, zero air, which should not contain any ionizable gases or vapors, is used to set the 2020ppbPRO’s zero point. Then, a calibration gas, containing a known concentration of a photoionizable gas or vapor, is used to set the sensitivity.
Regulators for Compressed Gases When connecting a regulator to a large cylinder: Ensure cylinder valve and regulator connection match. Ensure regulator construction materials are compatible with the gas, and that the cylinder pressure gauge will withstand the cylinder pressure. Never use the regulator as a shut-off valve. Close the cylinder when it is not in use. Do not subject the regulator to an inlet pressure greater than recommended.
Figure 17. Calibration with Flow-Match Calibrating the 2020ppbPRO with the Flow-Match Regulator 1. Ensure that the short sample probe is connected to the 2020ppbPRO filter tube holder inlet. NOTE: Ensure the sample probe is free of any contamination, as this will affect the calibration. 2. Press the CAL key. 3. Follow the instructions on the display and connect the intake sample conditioner tube (F1760162) and filter tube holder (A1790500).
7. Connect the span gas to the 2020ppbPRO tube holder inlet. 8. The 2020ppbPRO will take 60-90 seconds to set the span set point. When finished with the calibration, the 2020ppbPRO will display “Calibration complete”. 9. When the calibration procedure is finished, the display will show the lamp condition assessment (i.e., GOOD, REPLACE SOON, BAD). 10. Replace the filter tube used during calibration with a fresh tube and the instrument will be ready for sampling use.

Also, unlike other UV lamp windows, LiF readily absorbs water from atmospheric humidity. When contaminated by moisture, the window loses its ability to transmit UV light. NOTE: Do not touch the lamp window or handle it near water. Using the 11.7 eV UV Lamp With an 11.7 eV lamp installed, your instrument functions as a detector responding to compounds which ionize at 11.7 eV or less. The 11.7 eV lamp may be useful for detecting compounds not ionized by the standard 10.6 eV lamp.
Off-Line Charger General Information The off-line charger (Part No. MX350019) allows you to charge a battery pack independently of the 2020ppbPRO. To charge a battery pack without removing it from the 2020ppbPRO, see Battery Charging on page 39. The off-line charger requires one of the following the 2020ppbPRO accessories for operation: AC Adapter (Part No. MX350002 - North America) AC Adapter (Part No. MX396013 - Europe) DC Power Cord (Part No.
8. When the battery pack is fully charged, remove the AC adapter, first from the wall outlet, then from the off line charger. 9. Remove the battery pack connector from the socket on the off-line charger. 10. Replace the battery pack in the 2020ppbPRO as outlined in Removing and Replacing the Battery Pack on page 38. You can keep the battery pack fully charged indefinitely, without overcharging it, by leaving it connected to the off-line charger while the charger is operating.
Routine Maintenance ISP-074-576-P1D 6 75
Battery Charging A fully charged battery pack powers the 2020ppbPRO for approximately 8 hours. If the instrument is to be used for more than 8 hours, carry a spare battery pack (Part No. MX700010 or MX700011). When the first one has been discharged, replace it with the spare. NOTE: If you do not turn the 2020ppbPRO off before removing the battery pack, you will reset the instrument and you will lose all logged data and setup parameters.
to avoid loss of data. See Battery Charging on page 38 for instructions on charging the battery. Please observe the following: For replacement battery pack use only Part No. MX700010 or MX700011. Do not dispose of the battery pack in a fire. The cell may explode. The battery pack is 24% cadmium (Cd) by weight. This battery pack must be disposed of properly. Check with local codes for special disposal instructions. Do not open or mutilate the battery pack.
Figure 21. Removing the UV Lamp NOTE: Do not force the lamp into the lamp holder. 5. Replace the lamp housing cover. Tighten the cover down. Do not over tighten. 6. Calibrate the 2020ppbPRO and then continue normal operation. Cleaning the UV Lamp Window During the course of normal operation, a film builds up on the window of the UV lamp. The rate at which the film develops depends on the type and concentration of the gases and vapors being sampled and results from the UV light interacting with them.
The UV lamp cleaning kit (Part No. MX380336) includes aluminum oxide powder (3.0-micron powder) and cotton swabs. Additionally, you will require approximately 10 mL of methanol. When ordering methanol, specify purge and trap grade. The instructions provided below are for 10.6 eV lamps. Refer to Cleaning the Lithium Fluoride Window for special instructions to clean the 11.7 eV lamp window. Never touch the UV lamp window with your fingers. WARNING To clean the UV lamp: 1.
Cleaning the Lithium Fluoride Window To clean the 11.7 eV lamp window: 1. Clean the lamp window with dry aluminum oxide powder on a dry cotton swab. Do not use methanol or water. 2. Wipe the window and the lamp with a dry, lint free tissue to remove any trace amounts of the cleaning compound and methanol. All traces of cleaning compound must be removed. NOTE: You may not be able to fully clean the 11.7 eV lamp window.
