HBPH-2W-9-MK2-LT HB Products Differential pH Sensor for NH3

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.The 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.Product Features:Simple wiring with 2-wire measurement technology.Measurement range: 0-14 pH - 4-20 mA.Accurate measurement - Resolution +/-0.01PhDifferential measurement technology with replaceable salt bridge.Low maintenance costs.Designed with "Semi-flush" design so as to minimise the build-up of dirt on the probe.
