Introduction: Application of solution absorption method to collect harmful gases in the ambient air, the filter gravimetric method to collect particulate matter in the ambient air, set to collect harmful gases, particulate matter in an integrated atmospheric sampler for unattended all-weather work, supporting PM2.5 cutter Can collect TSP, PM10, PM5, PM2.5 and other particles. Can be widely used in environmental monitoring, health and epidemic prevention, labor protection, research institutions and other departments for sampling of harmful gases and particulate matter. Features: 1, with small size, light weight, low noise, high intelligence, stable flow, reliable operation, gathering the atmosphere and particulate matter in one. 2, microcomputer control two air and particulate matter at the same time three sets of sampling system, with simultaneous sampling, separate sampling, multiple sampling, sampling every other day, sampling and other sampling cycle. 3, the use of imported wide temperature OLED display, a good man-machine interface illustrated, easy to operate, the Chinese graphical display, can work in ultra-low temperature environment. 4, dual air and particulate three sets of sampling systems are imported DC brushless suction pump, trouble-free use of time is greater than 10,000 hours. 5, the user can be optional AC and DC dual-use host, equipped with ZD-24 DC power supply box, can be sampled in the absence of AC occasions. 6, the use of imported sensors, high precision sampling flow, good stability, atmospheric pressure and temperature can be measured, according to the pressure and temperature, state conversion automatically. 7, can set the sampling flow, boot time, sampling time, interval time, cycle times and other parameters. 8, automatic fault protection function, within the specified time has not yet reached the set flow of automatic shutdown protection. 9, built-in rechargeable battery for AC power outage to save data exchange calls automatically resumed sampling, automatically deduct the sampling process power-down time, and for users to check the power-off time. 10, unique drying, filtration, anti-down suction three-in-one design of the drying cylinder, you can efficiently dry the moisture, filter dust and pour down the impact of reduced flow, to achieve long-term operation-free cleaning. 11, the meter automatically illuminated function, easy to read and set the flow, with gas color recognition, user-friendly identification of gas. 12, the user can waterproof the keyboard calibration of the parameters of the instrument, but need to enter with a password to ensure instrument data security. 13, Sampling data automatically memory settings, the next boot priority, to achieve a key sample. 14, heating type: with built-in heating device, heating temperature can be set directly absorbed bottle temperature, temperature can be sampled at low temperature. Constant temperature type: with built-in incubator, heating and cooling, set the temperature range, when the ambient temperature is lower than or higher than the set temperature, the thermostat automatically heating or cooling to the set temperature. 15, tripod-style desktop design for the convenience of users, cutters are made of aluminum alloy anti-static adsorption. 16, data storage function, 10000 sets of data can be stored, either fast print or computer communication, convenient data storage. Technical Parameters: The main parameters: parameter range Atmospheric Sampler: Dual (0.1 ~ 1.0) L / min Dust sampling flow: (50 ~ 150) L / min Pre-pressure: (-30 ~ 0) Kpa Diaphragm effective diameter: Particles φ80mm radioactive aerosol φ50mm The largest sampling volume: 999999.99L Control mode: automatic or manual, within 24 hours arbitrarily set on-off time Delay time: 1min ~ 99h59min Sampling time: 1min ~ 99h59min Timing boot: 1min ~ 99h59min Interval time: 1min ~ 99h59min Atmospheric pressure: (70 ~ 130) Kpa Flow stability: ≤ 2% (change in resistance 3 Kpa ~ 6Kpa, grid fluctuations ≤ ± 10%) Flow response: <5S Timing accuracy: 24 hours ± 2S Sampling times: 1 ~ 99 times Power-off protection time: more than 3 years Pre-temperature: (-30 ~ + 99) ℃ Heating temperature range: (10 ~ 30) ℃, the factory set 23 ℃ Thermostatic temperature range: (15 ~ 30) ℃, the factory set 23 ℃ Working power: AC220V ± 10% 50Hz or external DC12V (optional) Noise: <50dB (A) Power consumption: <20W (excluding heater and incubator) Overall dimensions: (length 255 × width 265 × height 185) mm Machine weight: about 7kg
