Features: Multi-function: can simultaneously detect the formaldehyde in indoor air,, toluene, benzene, ammonia, TVOC and harmful gases 2. The flow stability: in order to meet the needs of the indoor environment monitoring, the instrument USES large flow pump, adjustable resistance meter, steady flow, the characteristics of high precision, can adapt to, toluene, benzene, ammonia, TVOC and other test tube has a larger sampling resistance; 3. Automatic control: can be set arbitrary in 0 ~ 99 minutes time, easy to operate, intuitive, sampling at the end of the automatic stop working; 4. The branch control: this instrument adopts 6 motor, pump, big flow, independent gas path structure, in the process of sampling, the sampling flow noninterference, can choose according to actual needs 6 road work or any various gas path and work at the same time; 5. Beautiful: color film of face of PC panel, touch key, beautiful and delicate; Technical indicators: Determine floor: 0.02 mg/m3 (sampling volume for 10 liters) Measuring range: 0.00 to 4.00 mg/m3 (sampling volume for 10 liters) The accuracy of measurement: 0.01 Measurement methods: national standard method of phenol reagent Light source: LED silicon photodiode, wavelength of 630 nm Benzene, ammonia, toluene, xylene, TVOC Benzene (0.05 ~ 4 mg/m3) Ammonia (0.05 ~ 3 mg/m3) Toluene (0.05 ~ 4 mg/m3) Xylene (0.05 ~ 4 mg/m3) TVOC (0.05 ~ 4 mg/m3) Voltage: 220 vac Frequency: 50/60 hz Power: 5 * 2.5 W Traffic: 6 * 1.5 L/min Weight: 2.5 kg Detection range: 0.00 to 4.00 mg/m3 Working current: 5 a Appearance size: 40 * 28 * 16 cm
