The HI 8614 is a water-resistant pH transmitter designed with a high-impedance input to accept signals directly from a pH electrode. The signal is then processed by a special high-impedance amplifier, which transmits an output current directly proportional to the input signal but independent of changes in load or cable capacitance. Calibration is performed by adjustment of two independent trimmers for slope and offset.

Temperature compensation is performed by the transmitter's ATC circuitry when measurements are taken with a temperature probe attached, it is also possible to substitute a fixed resistor for the temperature probe, if ATC is not required. The transmitter can be connected to HANNA® controller HI 8510, HI 8710 or HI 8711, recorders, computers or any data monitoring device that accepts 4 to 20 mA input.

Four versions are available. The standard models HI 8614 and HI 8614L with an LCD, which allows easy verification and monitoring of measured values, and is easier to calibrate and maintain.

The HI 8614-01 and HI 8614L-01 are the same as the HI 8614 and HI 8614L but with a range extension in order to be connected to the new design of our HI 8510, HI 8710 and HI 8711 pH controllers.
