Model EC-F9-NH3 includes the company’s SensorCheck feature, a built-in system to monitor and predict the sensor’s electrical viability. The gas diffusion unit with linear output exhibits excellent zero and calibration stability. Simplified, in-place calibration and cell replacement eliminate maintenance downtime. An optional LCD display indicates gas concentration in parts per million during normal operation and shows sensor operation status for changes in operating mode, calibration procedures and troubleshooting. Two external pushbuttons are used to navigate test functions and operating modes. An internal pushbutton and group of LEDs are also installed on the PCB to be used in the absence of the LCD module.
