Hangzhou Chunlai Technology CO., Ltd. products

The LGT-3000 is an in-situ through-type instrument developed based on TDLAS technology, which can conduct in-situ measurement of O2, CO, NH3, CO2, CH4, HCl, HF and other gases, as well as simultaneous monitoring of 1~4 components. The main functional module consists of a transmitting unit and a receiving unit. The transmitting unit mainly drives the semiconductor laser to emit laser light of specific wavelengths, which pass through the measured environment, and then the receiving unit carries out the optoelectronic conversion, signal processing and spectral data analysis so as to obtain the measurement results.

LGT-300 Laser Gas Analyzer is a high-precision gas analyzer developed based on Tunable Diode Laser Absorption Spectroscopy (TDLAS), and can realize in-situ single-end measurement of gas concentration. The analyzer can online analyze multiple gases including O2, CO, NH3, H2S, CO2, N2O, HCN, H2O, etc. In addition, it can achieve the online calibration function of any other gases except H2O.

LGT-350 Laser Humidity Analyzer is a high-precision humidity analysis product based on Tunable Diode Laser Absorption Spectroscopy (TDLAS), which can measure humidity in in-situ single ended method. The product adopts imported semiconductor laser as light source. It regulates laser frequency through modulating working current intensity of the semiconductor laser to make scanning range is slightly larger than absorption line of measured gas. When measured gas is absorbing in frequency selection, laser intensity will attenuate. The instrument can obtain concentration of measured gas by detecting attenuation information of laser intensity.

LGT-450 Flue Gas Analyzer is a highly integrated single-flange gas monitoring equipment, of which, core detection module adopts Tunable Diode Laser Absorption Spectroscopy (TDLAS) and Differential Optical Absorption Spectroscopy (DOAS) gas absorption technology with independent intellectual property rights. The specially designed measuring cell effectively improves optical path length for gas absorption, which can measure trace gas accurately inside pipeline. One equipment can realize online monitoring for multiple gas components, such as CO, CO2, SO2, NO, NO2, etc.

LGT-100 is a kind of explosion-isolation in-situ probe type tunable laser gas analyzer, which is developed for industrial online analysis and environmental online monitoring. It can online analyze O2, CO, NH3, CO2, CH4, H2O, HCl, HF, HCN and other gases under various complex working conditions(Note: a single analyzer can only analyze 1~2 components). The measured gas concentration ranges from constant to trace.

LGT-180 is a kind of panel-mounted tunable laser gas analyzer, which is developed for industrial online analysis and environmental online monitoring. The analyzer adopts white pool to realize the return of optical path. The optical path can reach 25m and the detection limit is low. It can online analyze O2, CO, NH3, CO2, CH4, H2O, HCl, HF, HCN and other gases under various complex working conditions (Note: a single analyzer can only analyze 1~2 components). The measured gas concentration ranges from constant to trace.

LGT-160 is a kind of explosion-isolation by-pass tunable laser gas analyzer, which is developed for industrial online analysis and environmental online monitoring, especially suitable for high temperature, high humidity, high dust, high pressure and other harsh working conditions, as well as small pipelines and other occasions which are not suitable for in-situ installation and measurement. It can online analyze O2, CO, NH3, CO2, CH4, H2O, HCl, HF, HCN and other gases under various complex working conditions (Note: a single analyzer can only analyze 1~2 components). The measured gas concentration ranges from constant to trace.
