挪威NEO在線氣體分析儀可以分析如H2S,CO2等氣體,能適應(yīng)眾多防爆領(lǐng)域.
Using tuneable diode laser absorption spectroscopy (TDLAS), LaserGas II is a family of analysers for fast and reliable measurement of single gases. Introduced to the market in 1995 and since employed in more than 2000 LaserGas monitors worldwide, TDLAS is a well-proven and reliable technology for demanding industrial applications. NEO Monitors?range of Tuneable Diode Laser (TDL) Analysers has been continuously perfected maintaining our technological edge with unrivalled detection limits. LaserGas II instruments employ the measurement principle known as 憇ingle line spectroscopy? which eliminates cross interference from other gases and enables very low concentrations of gas to be detected (see Technology for more information). TDLAS is a versatile tool for process control and emission monitoring with the following key features: Immediate response to concentration changes In-situ measurement, eliminates sample handling No cross interference from background gases Stable calibration, no zero drift Broad dynamic range (ppb, ppm, * level) Wide range of measurable gases (O2, CO, CO2, HF, HCl, NH3? Different Applications require different Configurations Available in the LaserGas II product line: Single Path Monitor (stacks, ducts, process chambers) Single Path compact (pipes, measurement cells) Open Path Monitor (long distance monitoring) Multipass Monitor (extractive trace measurements) Vial Tester (quality control of vials)
