6 gal polyethylene (with polypropylene cap)

Two Bottle Sampling: Set of two 2.5 gal glass (with Teflon

®

-lined lid) or 

3 gal polyethylene bottle (with polypropylene cap)

Four Bottle Sampling: Set of four 2.5 gal glass (with Teflon-lined lid) or 
3 gal polyethylene bottles (with polypropylene cap)

Eight Bottle Sampling: Set of eight 1.9 liter glass bottles (with Teflon-lined lid) or 
2.3 L polyethylene bottles (with polypropylene cap)

Twenty-four Bottle Sampling: Set of twenty-four 350 mL glass bottles (with Teflon-lined lid) or 
1000 mL polyethylene bottles (with polypropylene cap)

Stores up to five separate sampling programs. 

Allows using two samplers in combination where the first sampler at the completion of the 
program initiates the second.

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.

Alerts operator to low main battery, low memory power, plugged intake, jammed distributor 
arm, sample collected, and purge failure.

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.

Programmed in milliliters, in one mL increments from 10 to 9999 mL.

±5% typical

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. 

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.

Multiple Bottle Mode: Programming allows multiple samples per bottle and/or multiple bottles 
per sample collection.
