M40 Pro is an upgraded version of Industrial Scientific's classic product M40, which has many advantages that M40 does not have.
Smart Sensor
Adopting industrial grade sensors, equipped with ultra-high computing efficiency CPU chips, with temperature and humidity compensation, can improve linearity, has self-protection function, avoids high concentration gas damage, and thus extends the use time of the sensor.
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.
