Diffuse irradiance measurements: Diffuse Horizontal Irradiance measurements are performed with a thermopile sensor called Pyranometer mounted on a Sun tracker or shading ring. When the pyranometer is installed on an automatic sun tracker, the diffuse radiation can be measured in two different ways. Measuring Diffuse irradiance requires an accurate pyranometer with low offset properties. Duirng clear sky conditions the DHI irradiance (W/m2) is less than 20% of the total irradiance. Zero offsets lead to underestimat...
According to US EPA IO - 3.3 standard method of heavy metals, flue gas heavy metals analyzer uses XRF nondestructive testing technology and flue gas automatic enrichment technology to realize the accurate measurement of flue gas heavy metals such as waste incineration plants, cement plants, thermal power plants, etc.
Urban pollution is a problem that concerns more and more people in charge of public health. In large cities, car emissions are an important source of atmospheric pollution. This problem is growing as the traffic keeps on increasing. BTEX compounds are present in car emissions. It is therefore important to be able to analyze them with short analysis cycle duration and on a continuous and automatic way.
Determining levels of CO and CO2 and their respective ratio in the oxychlorination reactor contributes to overall process efficiency. The on-line analyzer system uses a selective CO/CO2 measurement by means of multi-wavelength infrared with automatic optical span possibility.
The purpose of determining ethylene in the oxychlorination process is to minimize ethylene losses by feedback control of C2H4 / Cl2 ratio in the oxychlorination reactor. The on-line analyzer system uses a selective C2H4 measurement by means of multi-wavelength infrared with automatic optical span possibility.
The purpose of determining ethylene in the chlorination process is to minimize ethylene losses by feedback control of C2H4 / Cl2 ratio in the chlorination reactor. The on-line analyzer system uses selective C2H4 measurement by means of multi-wavelength infrared with automatic optical span possibility. For all other analytical solutions in the chlorination process.
Environics® Ambient Monitor Calibrator with Ozone Generators facilitate dynamic calibration of ambient air analyzers. These instruments automatically perform zero, precision, span and multi-point calibrations using NO, NO2, SO2, CO, O3, hydrocarbons and other gases of interest. All ozone generators are factory calibrated using a NIST traceable ozone standard. The Series 6100, Series 6103 and Series 9100 all meet or exceed U.S. Environmental Protection Agency requirements.
