M40 Pro portable multi gas detector-Global supplier

M40 Pro is an upgraded version of Industrial Scientific's classic product M40, which has many advantages that M40 does not have. The M40 Pro can simultaneously detect combustible gas, oxygen, carbon monoxide, and hydrogen sulfide. intelligence sensor
Adopting a new generation of industrial grade sensors, equipped with ultra-high computational efficiency CPU chips, temperature and humidity compensation, improving linearity, self-protection function, avoiding high concentration gas damage, and thus extending the sensor's service life.
New type of sampling pump
The new servo system sampling pump has a 33 meter ultra long sampling capability and a high-power output motor, greatly expanding the sampling radius and enhancing the ability to capture gas molecules.
Two key operation
The double button "confirm" and "select" buttons are used immediately upon startup, with simple operation, clear display, and reduced misoperation.
