Sampling Features
Multiple Programs Stores up to five separate sampling programs.
Cascade
Allows using two samplers in combination where the first sampler at the completion of the
program initiates the second.
Upset Sampling
When equipped with integral flow meter, pH/temperature/ORP meter, conductivity, and/or
D.O. monitoring options, sampling can be triggered upon an upset condition when field
selectable limits are exceeded, concurrent with normal sampling routine, sample liquid is
deposited in designated “trouble bottle(s)”. Can also be triggered from an external trigger.
Status Output
Alerts operator to low main battery, low memory power, plugged intake, jammed distributor
arm, sample collected, and purge failure.
Automatic Shutdown
Multiple Bottle Mode: After complete revolution of distributor arm (unless Continuous Mode
selected). Composite Mode: After preset number of samples have been delivered to
composite container, from 1–999 samples, or upon full container.
Sample Volume Programmed in milliliters, in one mL increments from 10 to 9999 mL.
Sample Volume
Repeatability
±5% typical
Sampling Interval
Time Proportional Sampling: Selectable in single increments from 1 to 9999 minutes in one
minute increments.
Flow Proportional Sampling: Continuous Volume, Variable Time (CVVT): 1 to 9999 “units” of
flow volume, where “units” are whatever is set up for in the integral flow option or -1 to 9999
external-meter flow pulses: (momentary contact closure 25 msec. Or 5–12 V dc pulse;
4–20 mA interface optional)
Flow Proportional Sampling: Constant Time, Variable Volume (CTVV):
Format: 999: 00 hrs:min. Selectable in 1-minute increments of 1 to 59,940 minutes.
Interval Between
Samples
Selectable in single increments form 1 to 9,999 flow pulses (momentary contact closure
25 msec. or 5–10 V dc pulse; 4–20 mA interface optional), or 1 to 9,999 minutes in one
minute increments, or 1 to 9,999,999 “units” of volume, where “units” are whatever is set up
for the integral flow option.
Multiplex (Multiple Bottle
Mode)
Multiple Bottle Mode: Programming allows multiple samples per bottle and/or multiple bottles
per sample collection.
