Environmental monitoring usually involves items such as atmosphere, water quality, food, soil, public health, occupational hygiene, noise, vibration, radiation, etc. The relevant testing equipment includes:

Air Pollution
1. Atmospheric environment monitoring instruments (environmental monitoring stations, environmental protection bureaus, third-party testing, etc.)
(1) Environmental monitoring instruments

1. Atmospheric sampler: used for sampling of ambient air, toxic and harmful gases, formaldehyde, ammonia, TVOC, benzene, etc. in the workplace

2. Particulate matter sampler: capture total suspended particulates (TSP) and respirable particulates (PM10) or fine particles (PM2.5) in the ambient atmosphere

3. Atmospheric particulate matter comprehensive sampler: collects various harmful gases in the ambient atmosphere and indoor air, and captures total suspended particles (TSP) and inhalable particles (PM10, PM2.5) in the ambient atmosphere

4. Air fluoride sampler: used for the collection of fluoride and heavy metals in the environment

5. Volatile organic compound sampler: sampling of volatile organic compounds in ambient air, adsorption tube method

6. Precipitation and dust sampling device: it has the functions of melting snow, refrigeration, dust and precipitation

7. Soap film flowmeter: calibrate the small flow sampler, the range is optional

(2) Exhaust gas detection of fixed pollution sources

1. Automatic soot and flue gas tester: measure soot, O2, SO2, NO, NO2, CO, CO2, H2S

2. Asphalt smoke sampling gun: fixed pollution source waste gas asphalt smoke detection

3. Fluoride sampling gun: detection of fluoride in waste gas from fixed pollution sources

4. Oil fume sampling gun: fixed pollution source exhaust gas oil fume detection

5. Low-concentration smoke and dust sampling gun: fixed pollution source smoke and dust filter method detection

6. Flue gas sampler: fixed pollution source exhaust gas sampling

7. Volatile organic compound sampler: fixed pollution source volatile organic compound sampling, adsorption tube method

8. Non-methane total hydrocarbon sampler: total hydrocarbon, non-methane total hydrocarbon, methane sampling

9. Ringelmann smoke blackness tester: 1000 meters, smoke blackness measurement
 
10. Comprehensive flow calibrator: calibrate flow, pressure, etc. http://m.sdlysn.cn
