sf6 gas Equipment from DILO in South Africa | Environmental XPRT

The cordless battery-operated LEAKSPY Sulfr hexafluoride precisely measures Sulfr hexafluoride concentration in air by means of a non dispersive infrared sensor (NDIR sensor) and indicates the value on a graphic display in ppmv. The device allows precise localisation of leaks by searching the highest sf 6 concentration.Get price

NDIR - Ci Semi

Non Dispersive Infra Red (NDIR) technology uses a few wavelengths of light to gain information about a fluidcomposition. This analytical method is simple, inexpensive, and reliable. It is suitable for simple mixtures, or for instances when one component has a distinct characteristic wavelength that the NDIR instrument can measure at.Get price


A long-term experience in the behaviour of these mixtures and the technical challenges in preparing batches of very similar mixtures is available at the pilot laboratory. Seven laboratories participated: CMI-CHMI (Czech Republic), GUM (Poland), IMGC (Italy), IPQ (Portugal), CSIR-NML (South Africa), SMU (Slovak Republic) and NMi (Netherlands).Get price
