Model 695pH -Industrial pH Transmitter
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.
