Hanna Instruments-98143-20 pH and EC Transmitter with Isolated Output
Direct connection of the probes to the transmitter assure a positive electrical connection with no signal loss. This transmitter is most useful in remote process control applications.
Four models are available, transmitting a 0-1 V, 0-4 V or 4-20 mA signal. The output signals are proportional to the input signals but independent of changes in load or cable capacitance. Temperature compensation for conductivity measurements is performed by the transmitter's ATC circuitry.
The transmitter can be connected to any pH or conductivity controller, recorder, computer or any data monitoring device that accepts 0 to 1 V, 0 to 4 V or 4 to 20 mA input. Hanna Instruments-98143 is an ideal tool for applications that require the monitoring of both pH and conductivity at the same time.
The Hanna Instruments-98143-22 model has been specifically designed to be used with the Hanna Instruments-8000 fertigation controllers.
