PORTABLE SINGLE GAS DETECTOR

PORTABLE SINGLE GAS DETECTOR

Application:

BK-EA903  portable  single   gas  detector  is widely used in gas concentration detection. Adopt the imported electrochemical gas sensors and microcontroller technology.With fast  response,  high  accuracy,  stability  and repeatability.The parameters may be custom ordered, 

which is easy to operate.


Features: 

* Adopt  32-bit  microprocessor,  24-bit  ADC data collection chip. 

* Show various technical indicators and gas concentration values, historical data, data storage ,export and other 

functions.

* 2.4-inch industrial-grade HD color screen, resolution is 320*480 .

* PPM,% VOL, mg / m3 three concentration units are free to switch.

* Various modes can be adjusted: detection mode, storage mode, display mode, air pump mode.

* With  over-voltage  protection,  overcharge  protection,  anti-static  electricity  interference,  magnetic  field interference and other functions.

* With software automatic calibration, up to 6 levels targe point-calibration function to ensure the accuracy and linearity of the measurement.

* With ambient-temperature compensation function, dustproof, waterproof design and a dust filter which can be 

used for a variety of harsh conditions.
