Phionics

Phionics makes the STs Series™ water quality sensors: compact units with a 4-20 mA output, built to work with a data logger or an RTU for real-time monitoring. HenSistemas carries the conductivity and temperature sensor/transmitter, isolated and two-wire, with an easy-to-clean electrode, and the dual-output pH and temperature sensor.

The small diameter lets you fit the sensors into tight spots, and on the pH model every part, cable included, can be swapped without tools thanks to the patented pHiConn™ system.
