  • Large LCD Screen
  • High Accuracy
  • Manual/Auto Temp. Compensation
  • Wide Power Supply Range
  • High Input Impedance
Industrial pH Transmitters Product Description

The industrial pH transmitter is a 2-wire 4-20 mA pH transmitter enclosed in a sealed NEMA-4 enclosure.  The industrial pH transmitter has an LCD screen powered by 11 to 80 VDC.  The pH transmitter’s span has selectable pH values from 1 to 14 pH units via an internal dip switch.  The industrial pH transmitter uses BNC connections for the pH transmitter’s pH probe and has tinned leads for a 3-K Balco ATC temperature probe or simulation resistor (3K resistor included).  NOTE: If you will be using the industrial pH transmitter to monitor liquid with a pH close to 7pH or if your water temperature is close to 77°F the 3-K Balco ATC temperature probe will not be needed.

Global Water's GL500 pH Recorder adds recording capabilities to the industrial pH transmitters.  The GL500 pH Recorder connects to the pH transmitter's 4-20mA output to record data.  In addition, Global Water offers the PC300 pH Controller to use the industrial pH transmitter's output to control pumps or alarms.
