FN316C Explosion-proof Infrared Gas Analyzer is a kind of non-dispersive infrared gas analytical instrument whose operating principle is based on the selective absorption of infrared by some gases. Compared with similar products, its most striking characteristics are high stability, high reliability, and high selectivity.
Application fields:
Widely applicable to industries of chemicals, petroleum, metallurgy, synthetic ammonia, natural gas, and coking and to sectors of environmental protection, agriculture, medical treatment and health, etc.
Instrument characteristics:
Imported infrared sensor adopted, featuring long service life, high sensitivity, and quick response; 320×240 lattice LCD;
Chinese human-machine dialog menu, making operation intuitive and convenient; timed automatic storing function, and stored data and curves available for viewing at any time;
Upper/lower limit control point can be set at will within the whole range; standard RS232 or RS485 communication interface available for two-way communication with computer; isolated explosion-proof case adopted, so that the instrument can be directly installed on the site.
