STs001r4_20s ORP (redox) and Temperature Transmitter

The ST series of submersible water quality transmitters has an integrated preamplifier and a true 2-wire 4-20 mA transmitter.

Two independent channels simultaneously transmit an ORP signal (oxidation-reduction potential - redox) and temperature - two cables for ORP (redox) and two cables for temperature. The compact design of the patented pHiConn (TM) keyless connection system - and the 316SS (optional titanium) and the Delrin construction - make the robust sensor / transmitter ideal for applications such as process control, data acquisition, data processing wastewater and groundwater monitoring.

Units can be submerged at 200 feet (approximately 100 psi).

The individual units can be combined to make redundant or multiparameter modules using the patented pHionics pHiKLIP (TM) system.

The pHiKLIP (TM) system also allows units to be used in online applications (insertion) without fear of explosion.

As with all pHionics designs, the sensors / transmitters are designed with "ease of service" as the main objective.
