Global Waters pH sensor is a rugged reliablewater pH measuring device. The pH sensors are mounted on 25 of marinegrade cable, with lengths up to 500 available upon request. The pHsensor output is 4-20 mA with a three wire configuration. The pH sensor’selectronics are completely encapsulated in marine grade epoxy within a stainlesssteel housing (online version has 1 PVC x 8 pipe nipple, threaded bothends with cap). The pH sensors also use removable shields and replaceablepH sensor elements for easy maintenance.
Global Water’s GL500 pH Recorder adds recordingcapabilities to the pH sensors. The GL500 pH Recorder connects to the pHsensor’s 4-20mA output to record data. In addition, Global Water offersthe PC300 pH Controller to use the pH sensor’s output to control pumps oralarms.
