OPSIS initially based all of its gas analysers on the differential optical absorption spectroscopy (DOAS) technology. It utilizes a broadband (white) light source and the spectral analysis is made over a fairly wide wavelength window, typically some tenths of nanometres. The light sources are fairly simple arc lamps while the complex technology is found in the spectrometers or interferometers ...
Metal Powder Flowability Tester HFlow-1 tests the flowability of metal powder by measuring whether the sample can flow through the 2.5mm standard funnel.The design and production of HFlow-1 Hall flow ...
Iron and steel-making plants adopt combustion gases and inert gases as fuel or protection gases in the iron-making process. At the same time, the iron-making process will generate a variety of process gases, such as CO and O2. Thus, early detection ...

Formaldehyde, chemical formula HCHO or CH2O, is a colorless gas with a pungent odor. Levels above 0.1 ppm can cause allergy and acute health problems, e.g. sore throat, skin irritation, nausea, scratchy eyes and cough. Formaldehyde (HCHO) is also classified as highly carcinogenic compound. Exposure to moderate amounts of HCHO has been linked to cancer, such as leukemia.
