Combustible gas detector transmitter

GRI 8404 Portable Combustible(Ex)Gas Detector

GRI 8404 Portable Combustible(electrochemical) gas detector is a kind of intellectual handheld alarm with high accuracy low consumption; detect the concentration of the toxic gas with advanced electrochemical technology in the target gases. 

GRI-8404 series is natural diffused gas detection way, the sensitive component adopt the toxic gas sensors imported Switzerland Membrapor electrochemical, with very high sensitivity and excellent repeatability; with a LCD display screen, can on line observe the concentration value of the target gas; can check the time ,Date and week, can output USB digital signal, communicate with monitor or PC; With two level alarm output, immediately start the light and sound alarm signal once exceed the preset point; with soft/hard two kind ways of calibration, can calibrate without off cap.

GRI-8402 series can be widely used in factory,office ,warehouse,mine and other varies environment field for toxic gas detection.

Feature:

Switzerland electrochemical sensor, stable and reliable performance;

External power supply DC5V, build-in rechargeable 3.7V Lithium batteries, chargeable on communication; 

Big screen LCD can display each parameter;
