Product Description
Global Water’s pH sensor is a rugged reliable water pH measuring device. The pH transmitter is mounted on 25’ of marine grade cable, with lengths up to 500’ available upon request. The pH sensor output is 4-20 mA with a three wire configuration. The pH transmitter's electronics are completely encapsulated in marine grade epoxy within a stainless steel housing (online version has 1” PVC x 8” pipe nipple, threaded both ends with cap). The pH transmitter also uses a removable shield and replaceable pH sensor element for easy maintenance.
Global Water's GL500 pH Recorder adds recording capabilities to the pH transmitter. The GL500 pH Recorder connects to the pH sensor's 4-20mA output to record data. In addition, Global Water offers the PC300 pH Controller to use the pH transmitter's output to control pumps or alarms.
