Air purged automatically before and after each sample; duration automatically compensates
for varying intake line lengths.
High impact injection molded ABS; submersible, watertight, dust tight, corrosion & ice
resistant; NEMA 4X,6.
Indicates real time and date; 0.007% time base accuracy.
Initiates a sample collection independent of program in progress.
Intake line automatically rinsed with source liquid prior to each sample, from 0 to 3 rinses.
Sample collection cycle automatically repeated from 0 to 3 times if sample is not obtained on
initial attempt.
