    Brief introduction:

    ● Compatible with all DRFN digital pH sensors;
    ● Separately have a list of controller and sensor settings for quick and detailed parameter setting;
    ● The working status of the sensor can be queried, including reading the serial number;
    ● Support a variety of installation methods;
    ● Time and historical data recording function;
    ● 3.2-inch large LCD screen;
    ● User-friendly English language interface;
    ● Password can be set to prevent misoperation;
    ● 2 SPST multi-function and settable relays;
    ● Two way 0/4~20mA active current loop outputs;
    ● RS485 interface, Modbus RTU communication protocol;
    ● IP66 waterproof level, sealed enclosure can isolate pollution and corrosive gas;

    The meter has a self-diagnostic function.

    It can diagnose the PH/ORP sensor during calibration and maintenance. If the operation is improper or the PH/ORP sensor has poor characteristics, the screen will display the image and the buzzer will prompt briefly. It is recommended that the user re-maintain or replace the sensor.

    The ORP PH controller can not only compensate the temperature of the test sample by connecting the temperature sensor, but also self-check the working temperature of the instrument in real-time. When the working temperature of the instrument changes, the instrument will compensate for the hardware changes caused by the temperature drift accordingly, making the detection result more accurate, this is a patented technology of daruifuno.
