GAOTek multi gas analyzers ,32 bit microprocessor,24 bit ADC data acquisition chip, outstanding accuracy. Three concentration units are available PPM,%VOL, mg/m3. Users can combine different sensors; 1-5 kinds of gas can be detected at the same time, PM 2.5 dust sensor, temperature and humidity sensor, and another kind of sensors are available. Up to 100,000 group data can be storage, user can view history data on the display and data output is available. It allow user to connect to portable printer to print data With temperature and humidity detection, user can detect temperature and humidity value on the scene or the temperature and humidity value inside the pipe. Five operation modes are optional Detection mode, Storage mode, Printing mode, Display mode, Pumping mode. With high-power pump allow device working under tiny negative pressure condition, the reasonable gas chamber design ensures that the sensor is not affected by the pressure. With over-voltage protection, overcharge protection, electrostatic prevention, magnetic-field interference prevention. All software automatic calibration, sensor up to 6 levels target calibration, ensure the accuracy and linearity of the entire measurement, also with data recovery function. Chinese and English operation model are available, user-friendly.

With temperature and humidity compensating function. With dust filter and dust-proof design allow device applies in all sort of harsh conditions.
