HI8614N without LCD HI8614N · HI8614LN · HI8615N · HI8615LN pH and ORP Transmitters with 4-20 mA Galvanically Isolated Output • ATC for pH models · Automatic temperature compensation • Waterpoof · Water resistant • Backlight · Backlit, LCD display for "L"models The HI8614N and HI8614LN are a waterresistant pH transmitters designed to be used with a standard high impedance pH probe with BNC connector. 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. These transmitters can be connected to Hanna controller HI8510, HI8710 or HI8711, recorders, computers or any data monitoring device that accepts 4 to 20 mA input. HI8615N and HI8615LN have been designed for transmitting ORP measurements from remote locations. These transmitters features two controls (one for 4 mA and one for 20 mA) to compensate for electronic drift and ambient temperature. These transmitters can be connected to Hanna HI8512, HI8720, or any recorders, computers or any data monitoring device that accepts 4 to 20 mA input. ”L” versions allow easy verification and monitoring of measured values and is easier to calibrate and maintain.
