IndustrialpH Transmitters and pH probes
IndustrialpH Transmitters Product Description
The industrial pHtransmitter is a 2-wire 4-20 mA pH transmitter enclosed in a sealed NEMA-4enclosure. The industrial pH transmitter has an LCD screen powered by 11to 80 VDC. The pH transmitters span has selectable pH values from 1 to14 pH units via an internal dip switch. The industrial pH transmitter usesBNC connections for the pH transmitters pH probe and has tinned leads for a3-K Balco ATC temperature probe or simulation resistor (3K resistor included). NOTE: If you will be using the industrial pH transmitter to monitor liquid witha pH close to 7pH or if your water temperature is close to 77°F the 3-K BalcoATC temperature probe will not be needed.
Recording
Global Water’s GL500 pHRecorder adds recording capabilities to the industrial pH transmitters. The GL500 pH Recorder connects to the pH transmitter’s 4-20mA output to recorddata. In addition, Global Water offers the PC300pH Controller to use the industrial pH transmitter’s output to control pumps oralarms.
