GRI-8413 Portable O3 Gas Alarm Detector

Product Description

GRI****3 Portable O3Gas Alarm Detector
Product summarize：
 
GRI****3 Portable O3 (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****3series 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****3 series can be widely used in factory、office、warehouse、mine and other varies environment field for toxic gas detection.
 
Main Features：
