Its precision in detecting this gas is due to an optical fluorescence sensor, the response of which is managed by a microcontroller. The percentage of oxygen present in the air is constantly shown on the display promptly informing you of the danger threshold.
The NASE25/K, portable Explosive Gas Concentration in the ambient Gauge detection accuracy is due to the Catalytic sensor. Thhe sensor is managed by a microprocessor whose function is to perform a self-calibration, to allow maximum precision during the measurement.
During the measurement of the dispersed gas the instrument emits an acoustic signal, modulated in frequency according to the gas quantity found, and to read directly on the display the concentration of gas present in the ambient.
Reading from 5% to 100% of LEL. with a resolution of 1% of LEL.
The NASE25/K reading can also be per formed in a low lighted environment as the display is backlit.
