Supply of formaldehyde detector formaldehyde detector formaldehyde Six-meter

SJ-JCLS-I Liu Heyi indoor air quality testing instrument instruction manual of the instrument in line with national standards "in public places Determination of formaldehyde in the air," the provisions of GB / T18204.26-2000 for good ranking Chongqing Environmental Protection Technology Co.'s proprietary energy After the simultaneous detection of six indoor air pollution gases (formaldehyde, benzene, ammonia, toluene, xylene, TVOC) field instrumentation, gas detection time each time by a microcomputer control system to adjust, to set the time automatically stop working, spectrophotometric and can live directly on the LCD formaldehyde readings result. Spectroscopic print program uses the most advanced international ts1230 spectroscopic techniques for optical frequency splitting formaldehyde detection reagent colorimetric, spectral samples obtained precise results. Built-in mini printer can print directly, formaldehyde concentration, the detection unit, detection date and time, exceeding the results of the conclusions, and the operation is simple, reasonable design, beautiful appearance. The instrument has passed all performance indicators Quantitative Research in Beijing tested up to the national standards and issued a certificate of inspection. The device can be used: for supervision, monitoring agencies, management companies, decoration companies, construction companies, factories, mines and workshops can also be used for research, teaching, laboratory. This instrument is applicable; bedroom, office, hotels, restaurants, shopping malls and other places, the instrument looks, easy to carry, suitable for field use. Formaldehyde detection principle: indoor air quality spectrophotometer detector principle is based on the sample of formaldehyde reagent reacts with blue compound selectively absorb visible light and the establishment of a colorimetric assay. By spectrophotometric module can show content of harmful gases in the sample directly on the LCD screen.
