EmailThe LGT-330 is a high-precision gas analyzer developed based on Tunable Diode Laser Absorption Spectroscopy (TDLAS). The analyzer provides online analysis of multiple gases including O2, CO, NH3, H2S, CO2, N2O, HCN, H2O, etc.
Optical non-contact measurement with low drift and long life;
Single-ended measurement: no need for complex adjustments of the optical path;
Single-line spectrum technology: free from cross interference of background gases;
Online calibration using optional online calibration modules, no need for dismantlement;
Alternative calibration technology to solve the problem of water standard gas production with high calibration accuracy;
In-situ measurement: with no need for a pretreatment system to avoid sampling adsorption, blockage and component damage in preprocessing, reducing operation cost.
Exhaust monitoring and process control in waste incineration plants, coal fired power plants, cement plants, glass factories, ceramic factories, sintering, coke oven, Desulfurization Technology and Denitration Technology, etc.
