GRI-8407 Portable SO2 Gas Alarm Detector

GRI-8407 Portable SO2 Gas Alarm Detector
Product summarize：

GRI-8407 Portable SO2 (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-8407series 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-8407 series can be widely used in factory、office 、warehouse、mine and other varies environment field for toxic gas detection.

Main Features：
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;
Can set and display time、date and week;
Intellectual design, full function, zero, alarm set, convenient for calibration;
Small shell can be put in the pocket or bag, hang on body, convenient for carry;
Two level light and sound alarm, 4 height light LED when the alarm mark the attention of users;
with one way USB digital signal output.

Industrial Application ：
Petroleum、petrochemical 、chemical 、gas、metallurgy、electricity 、municiple、telecommunication、construction safety detection of transportation tunnel、electronics、semiconductor industry and other places existed toxic and harmful gases.
