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.
The transmitter can be connected to controllers HI 8510, HI 8710 or HI 8711, recorders, computers or any data monitoring device that accepts 4 to 20 mA input. HI 8614L allows easy verification and monitoring of measured values, and is easier to calibrate and maintain.
