Sensaphone PH Sensor 4-20mA Fixed




Changes in pH can be critical to water quality. Whether it be in a swimming pool, more critical applications such as water and wastewater treatment facilities, or clean water applications such as laboratories, food, and beverage, HVAC systems, or healthcare, this integral two-wire 4-20mA pH transmitter can feed data directly to your Sensaphone device.


If set limits are exceeded, the Sensaphone will send alarms to appropriate personnel. The sensor includes a measuring range of 0 to 14pH, replaceable salt-bridge for extended service life, flow-thru, hot-tap or submersible mounting, and automatic temperature compensation.
