The BASI BPHT-100 pH transmitter is ideal for monitoring of pH. Complete electrical isolation between measuring circuit supply and the 4-20mA output is provided.

The BPHT-100  is compatible with most pH electrodes.

The transmitter is housed in a compact DIN case enclosure suitable for panel mounting.

The digital display provides a continuous display of the pH level and provides a convenient on the spot display during calibration and setting up.  Easy to follow on display messages assist the user to set up and calibrate the transmitter.

Two point calibration provides a thorough calibration using two accurate buffer solutions.
