The HI8614N is a water-resistant pH transmitter is designed to be used with a standard high impedance pH probe with BNC connector. The signal is then processed by a special highimpedance amplifier, which transmits an output current directly proportional to the input signal but independent of changes in load or cable capacitance.

Temperature compensation ensures fast, accurately compensated readings even during sudden temperature fluctuations.
Water resistant design for use in process control.
HI8614LN has optional backlit, LCD display for easy viewing (no LCD on HI8614N).

Automatic Temperature Compensation (ATC)

Temperature compensation is performed by the transmitter's ATC (Automatic Temperature Compensation) circuitry when measurements are taken with a temperature probe attached; if ATC is not required, it is also possible to substitute a fixed resistor for the temperature probe.

Easy Calibration

Calibration is performed by the adjustment of two independent trimmers — slope and offset.

Flexible for Your Needs

The transmitter can be connected to any Hanna controller that accepts analog input.

BNC Connector

The transmitters use a universal BNC socket for quick and secure connection to any electrode with a BNC connector.

Isolated Input

The input is isolated from the current loop to eliminate problems related to ground loop, low insulation cables, multiple electrode connections, and a common mode voltage of up to 100V ensures true differential readings.

Version with LCD

HI8614in.Lin. versions allow easy verification and monitoring of measured values and is easier to calibrate and maintain.
