I. product introduction
Onetest-g40 multi-gas detector (hereinafter referred to as the
detector) is a safe device that can continuously detect the
concentration of leaked gas. Advanced integrated circuit
technology, embedded microcomputer control, high quality imported
gas sensor, with excellent sensitivity and excellent repeatability;
Use dot matrix LCD display, support Chinese and English interface
and Chinese and English voice prompts, users can quickly understand
the product, use and maintenance is simple; The shell is made of
high strength engineering plastic material, good anti-seismic, high
strength, high-grade air appearance and has the function of
dustproof, waterproof and explosion-proof.
This detector is widely used in petroleum, chemical industry, environmental protection, metallurgy, refining, gas, biochemical medicine, agriculture, fire protection, archaeology and other industries and places that need safety monitoring of toxic and harmful, explosion prevention. Detection instrument can effectively predict the concentration of dangerous gas alarm, ensure the safety of staff life is not threatened, production equipment is not damaged.
This product is designed, manufactured and verified in accordance with the following national standards: Gb3836.1 -- 2010 explosive environment -- part 1: general requirements for equipment; GB3836.4 -- 2010 explosive environment -- part 4: equipment protected by intrinsically safe "I"; GB15322.3 -- 2003 portable combustible body detector -- part 3: Portable combustible body detector with measurement range of (0-100)%LEL "jjg693-2011" verification code of combustible body detection alarm "JJG365 -- 2008 verification code of electrochemical oxygen detector jjg695-2003 hydrogen sulfide detector JJG915 -- 2008 verification code of carbon dioxide detection alarm
