Listing Details

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. Recording
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 PC320 pH Controller to use the industrial pH transmitter's output to control pumps or alarms.
