CO2 Analyzer 2825/2830/2835 Notes ii Instruction 0019-9320
CO2 Analyzer 2825/2830/2835 1.0 INTRODUCTION 1.1 General Bacharach’s line of CO2 analyzers are easy to use, but it is essential that this instruction manual be read, understood, and followed by all operators and maintenance personnel prior to using or servicing the analyzer.
CO2 Analyzer 2825/2830/2835 1.3 Applications • Incubators • Food Packing • Mushroom Farms • Brewing • Fruit/Vegetable Storage • Carbonated Drink Dispensing • Greenhouses • Blended Beer Gases 1.4 Instruction Manual Unless otherwise noted, all sections in this instruction manual describe the operation and maintenance of all three CO2 analyzer models (2825 / 2830 / 2835).
CO2 Analyzer 2825/2830/2835 2.0 OPERATION 2.1 Important Note Always ensure that the analyzer’s gas inlet connector (Figure 1, Item A) and gas exhaust (Figure 1, Item B) are unobstructed and open to the atmosphere. Be careful not to breath directly on the analyzer while taking a measurement; otherwise, inaccurate readings will result. 2.2 Switching Analyzer ON/OFF Switch ON the analyzer by pressing the button.
CO2 Analyzer 2825/2830/2835 2.3 Probe Installation (2830 / 2835) 2.3.1 Temperature Probe Installation (2830) The 2030 Analyzer’s temperature sensor is mounted in a hand-held probe assembly that plugs into a separate socket on top of the analyzer (Figure 2). Before installing the probe, turn the analyzer OFF. Align the slot on the probe connector with the tab on the analyzer’s mating socket; then push the probe connector onto its socket until it bottoms.
CO2 Analyzer 2825/2830/2835 2.4 Pump Operation With the analyzer already switched ON, momentarily pressing the button will start and stop the internal pump. The optional Extended Probe Assembly with in-line filter (P/N 0019-3310) can be connected to the gas inlet fitting (Figure 1, Item A) on the top of the analyzer for drawing gas samples from hard-to-reach areas. If desired, a section of 1/8" I.D.
CO2 Analyzer 2825/2830/2835 2.6 Selecting the Measurement to be Displayed Depending upon the analyzer model, several different gases and environmental measurements can be taken as described in Section 1.1 General. Important! For the 2830/2835 analyzer to display accurate temperature readings, the temperature probe must be installed per Section 2.3. Note that if the temperature probe is removed, the analyzer will continue to provide accurate readings for all other measurements.
CO2 Analyzer 2825/2830/2835 2.7 Current / Peak Gas Reading Mode The analyzer can display either the current readings of all measurements, or peak gas readings. While displaying a gas reading, pressing and holding the f3 button for 3 seconds switches the analyzer to its peak reading mode. Note that a peak reading is the highest reading taken since the analyzer was switched ON.
CO2 Analyzer 2825/2830/2835 2.9 Battery Low Display When the battery nears depletion, the display will alternate between its normal display and the following “BattLow” display. BattLow 340 In addition, the beeper will emit three rapid notes every 30 seconds. At this time the analyzer should be given a full charge per Section 3.6 as soon as possible. 2.10 Battery Charge Display An indication of the battery’s charge is obtained by pressing the f2 button once.
CO2 Analyzer 2825/2830/2835 2.12 Powering Analyzer from Charger The analyzer can be continuously powered by its charger by connecting the charger to the analyzer in the following sequence: 1. Switch ON the analyzer without the charger attached. Note: Connecting the charger to an analyzer that is switched OFF causes the unit to enter its charging mode, which in turn prevents the analyzer from being switched ON. 2.
CO2 Analyzer 2825/2830/2835 2.14 Testing Incubators (2825 / 2830) When testing incubators with the Model 2825 / 2830, it is important to keep moisture from entering the analyzer. Moisture can contaminate the IR cell and affect the readings. When a desiccant filter (P/N 0007-1645) is installed, it will remove excess water vapor (humidity), refer to Section 2.13.
CO2 Analyzer 2825/2830/2835 3.0 MAINTENANCE 3.1 Cleaning Keep the analyzer clean by wiping it with a soft cloth dampened with a mild detergent solution. 3.2 Sunlight The unit should not be left out in direct sunlight, or in other areas where excessive heat exists, for long periods since component damage due to overheating may result. 3.3 Servicing There are no user-serviceable parts inside the analyzer. Unauthorized disassembly of the unit will invalidate the warranty. 3.
CO2 Analyzer 2825/2830/2835 Release the f2 button and perform an air calibration as described in Section 3.7 WARNING! Failure to perform an air calibration after resetting the analyzer to its factory settings may cause incorrect gas readings to be displayed. 3.6 Battery Charging When the ‘BattLow’ message is displayed (refer to Section 2.9), the analyzer must be recharged using the supplied battery charger.
CO2 Analyzer 2825/2830/2835 3.7 Air Calibration An air calibration consists of zeroing the gas sensor(s) in fresh outside air, which sets the CO2 sensor to read 340 ppm or 0.03% (2825 / 2830 / 2835) and the O2 sensor to read 21% (2825 / 2830). Important! It is essential to ensure that the analyzer is in fresh air before attempting an air calibration. If this condition is not ensured, incorrect gas readings will occur.
