Six air detector BRJ-R-II

Six air detector Model: BRJ-R-II Instrument: The instrument Scope: environmental protection, construction, workshop factories, decoration, indoor air testing governance indoor air quality testing company to carry out business, can also be used to study research institutions and teaching. Instrument features: 1, multi-function: can simultaneously detect indoor air formaldehyde, benzene, ammonia, toluene, xylene, TVOC harmful gases, the use of imported sensor chip, high-resolution large LCD blue screen full Chinese display, six detections sampling time independently controlled. 2, flow stability: In order to meet the needs of the indoor environment monitoring, the instrument uses a high flow pump, adjustable resistance to flow, with flow stability, high precision characteristics 3, automatic control: microcomputer control, can be arbitrarily set time , easy and intuitive, automatic stop for the sampling end; 4, appearance: color mask panel PC, LCD screen, touch buttons, exquisite beauty; 5, with a micro-printer: spectrophotometric print program uses the most advanced international ts1230 spectroscopic techniques, Built-in mini printer can print directly temperature, humidity, formaldehyde concentration, the detection unit, detection date and time, exceeding the results of the conclusions, and simple, rational design. 6, high precision: The instrument has passed the National Institute of Metrology index test, reached the national standard and issued a certificate of inspection, is currently the most advanced indoor air field testing equipment. Technical parameters: Voltage: 220V Frequency: 50HZ Power: 6 * 2.5W Detection limit: 0.02mg / m3 (the sample size is 5 liters) Measuring range: 0.00-2.20mg / m3 (sample volume of 5 liters) measured Accuracy: ± 2% light: LED silicon photo diode wavelength 630nm
