Description:
The GT-903-JM series gas detectors are the basic model of portable gas detectors. With import gas sensor and most advance nanometer semiconductor technology GT-903-JM series multifunctional gas detector can detect gases rapidly and precisely. It can be a single gas detector or 4-gases detector for LEL&O2&H2S&CO,and temperature and humidity detection function is also available if you need. Gas concentrations and history data can be displayed in the 2.4 inches LCD HD color screen,User can save concentration data、output data、detect temperature and humidity level.
Features:
Can be single gas detector or 4-gases detector(LEL & H2S & O2 & CO)
Three concentration units are available PPM,%VOL,mg/m3.
Up to 30,800 to 123,200 groups data can be storage,user can view history data on the display and data output is available.
With temperature and humidity detection,user can check temperature and humidity value in the environment or in the pipeline
Four operation modes are optional:Detection mode,Storage mode,Display mode,
Pumping mode.
With high-power pump allow instrument working under tiny negative pressure condition,the reasonable flow chamber design ensures that sensors are not affected by the pressure.
With over-voltage protection,overcharge protection,anti-electrostatic interference ,anti-magnetic-field interference
All software automatic calibration, each kind of sensor can calibrate up to 6 target concentration values to ensure the accuracy and linearity of the entire measurement
Chinese and English operation model are available,user-friendly.
Ideally suited for a wide range of applications with its rugged,reliable,and easy-to use design.
With temperature and humidity compensating function.With dust filter and dust-proof design allow instrument applies in all sorts of harsh conditions.
