TWI-PH1 Two-Wire Isolated pH Transmitter
Brand: Pribusin, IncThe TWI-PH1 is an isolated two wire pH transmitter in a small, easy to install package. It has easily accessible screw terminals and is built in a rugged housing. A standard BNC connector allows direct plug-in of the pH probe.
The TWI-PH1 consists of a pH signal conditioner complete with temperature compensation and an isolator. The temperature compensation is accomplished by means of a 3 KOhm thermistor. The isolated output prevents interaction between output signals if more than one pH transmitter is used in a system.
