Product Introduction
1. WQ201 pH Sensor Description
WQ201 pH SensorA rugged and reliable water pH measurement device. The pH transmitter is mounted on a 25-foot marine-grade cable and can be used at lengths up to 500 feet. The sensor output is 4-20 mA in a three-wire configuration. The WQ201's electronics are encapsulated in marine-grade epoxy inside a stainless steel housing. The unit also uses a removable shield and replaceable pH sensing element for easy maintenance.
2. WQ201 pH Sensor Recording and Control
With all 4-20 mA output sensors, you can add recording and control capabilities to the WQ201 with the GL500 data logger and PC320 controller. The GL500 connects to the pH sensor's 4-20 mA output to record data, and the PC320 controller connects to the sensor's output to control pumps or alarms.
