The ST series of individual rugged water quality sensors and transmitters are made of the highest quality materials (PVDF, 316SS or optional titanium, Teflon, Viton, etc) and are manufactured to exacting standards to provide you with years of trouble-free, and safe, service in demanding environments. Ease of service has always been the primary design goal — providing you with a low cost of ownership.

Probe Models
STsC series 4-20 mA output , two wire operation
The STcC series of submersible water quality transmitters have an integrated preamp and an isolated 4-20mA transmitter

Isolated 4-20mA output - operates down to 7 volts, up to 40 vdc

True 2 wire operation

Accurate transmission of signal to 5 km

Auto-polarity correction - operates if wires are accidentally reversed

STsV series voltage output, micropower transmitters
The STcV series of submersible water quality transmitters can be powered by any voltage source of 4 to 16 volts

Ideal for use with battery powered dataloggers

Consumes less than 50 microamps of current (typical)

Various outputs available, 0-1.00 , 0-2.50, 0.4 to 2.00 vdc etc

STsB series voltage output, with internal battery
The STcB series of submersible water quality transmitters have an integrated preamp and a 3.6 volt, field replaceable battery

Ideal for use with battery powered dataloggers - always on - no concerns about ‘turn-on time’
Three year typical battery life
Various outputs available, 0-1.00 , 0-2.50, 0.4 to 2.00 vdc etc
Uses standard 3.6v AA battery
