■ A new generation of intelligent sensors, equipped with effective chips
■ New servo system sampling pump, 33 meters ultra-long sampling
■ Up to 20 hours standby time

The M40 Pro is an upgraded version of the classic M40 from Insco, and it has many advantages that the M40 does not have. The M40 Pro can detect combustible gas, oxygen, carbon monoxide and hydrogen sulfide simultaneously.
Smart sensors
It adopts a new generation of industrial-grade sensors, equipped with ultra-high computing efficiency CPU chips, with temperature and humidity compensation, which can improve linearity, and has a self-protection function to avoid high-concentration gas damage, so as to extend the use time of the sensor.
New sampling pumps
The new servo system sampling pump, with 33 meters ultra-long sampling capacity and high-power output motor, greatly expands the sampling radius and greatly strengthens the ability to capture gas molecules.
Two-button operation
The two-button "confirm" and "select" buttons are ready to use at start-up, with simple operation, clear display and reduced misoperation.
