WQ201 pH Sensor
The pH sensor output is 4-20 mA with a three wire configuration. The pH sensor’s electronics are completely encapsulated in marine grade epoxy within a stainless steel housing (online version has 1 x 8 inch PVC pipe nipple, threaded both ends with cap). The pH sensors also use removable shields and replaceable pH sensor elements for easy maintenance.
FEATURES
• Fully encapsulated electronics
