HBPH-MK2-LT is a pH sensor designed for the extreme requirements of industrial refrigeration. It is used to measure the pH value of brine in case of an ammonia leak in a heat exchanger. Brine has a pH value of 7, and even for small leaks, the pH will rise to 9-10. The sensor is designed with differential measurement technology that ensures a minimum lifetime of 2 years for the sensor element.

This latest version HBPH-MK2-LT has an improved and protected universal flat-faced glass process electrode specially designed for tough applications.

The HBPH-MK2-LT -sensor can be used together with our “NH3/Brine leakage Display” type HBPH-C1 which is a controller used to calibrate and set up the alarm limit for the HBPH-MK2-LT sensor.

The HBPH-MK2-LT sensor comes with 3-pack salt bridge replacement kit.
