• Quickly detect the concentration of combustible gas and the measurement of ambient temperature and humidity. If the measurement exceeds the limit, an audible and visual vibration alarm will be issued.
• Misoperation recognition function: automatic identification and prevention of misoperation of concentration calibration, which can avoid defects caused by human factors
• Zero point automatic tracking, long-term use is not affected by zero point drift
• Resistant to high-intensity pulse surge electric shock. With anti-reverse function
