The pH transmitter features a pH probe which measures the electrochemical potential of a solution to determine its pH. The transmitter displays the pH measured by the probe and has a 4-20 mA output to transmit the measurement to a controller. The transmitter supports the HART communication protocol.

This multiparameter analytic transmitter features four digital sensor inputs and four analog outputs. The Heartbeat technology permits to monitor and verify the instrument and the probes health status.
