LB-70D High-Flow Low-Concentration Automatic Dust (Gas) Tester
Product Description
The instrument is a newly developed generation product meticulously crafted based on our company's existing LB-70C Automatic Smoke and Dust (Gas) Tester. Its technical performance specifications comply with the relevant regulations issued by the National Environmental Protection Bureau for smoke testers. It can automatically measure the concentrations of gases such as O2, SO2, NO, NO2, CO, CO2, and H2S in the exhaust gases emitted from various boilers and industrial furnaces. It also measures parameters including smoke dynamic pressure, static pressure, atmospheric pressure, temperature, humidity, and pressure before the flowmeter.
The product is widely used in environmental protection, testing companies, industrial and operational enterprises (power plants, cement factories, steel mills, paper mills, metallurgical factories, boiler furnaces, rubber factories, and so on), as well as in the aluminum, titanium, zinc industries, and in the fields of sanitation, scientific research, and education.
