 기능 (ASSIGNMENT)

Portable electrochemical gas analyzer MGL-19.5 is assigned for nitrogen dioxide (NO2) concentration measurement in working zone air, for sound and light alarm when admissible concentration is exceeded.

 

 운용원리 (PRINCIPLE OF OPERATION)

The electrochemical method of detection is in the basis of analyzer operation. Electrochemical sensor is used as a transducer. Measurable gas enters the sensor by diffusion and causes electrical current in electrodes, proportional to the gas concentration. Voltage from load resistor is directed to the transformer analogue to digital and indicated on the digital LCD.
