LGM1600 portable laser ammonia escape analyzer Introduction: LGM1600 is a portable multi-purpose ammonia analyzer, based on the gas absorption spectrum analysis technology, using the "fingerprint" absorption spectrum of ammonia molecules in the middle infrared, using the world's leading semiconductor quantum cascade laser (QCL) as the light source, the laser through the original MIR-SHORT ultra-small gas absorption cell, the photoelectric detector receives the transmitted light, extracts and analyzes the transmission spectrum, accurately retrieves the ammonia concentration, and realizes the high selection of ammonia molecules Anti-interference and high-precision measurement. characteristic: 1. Anti-interference and high precision: we choose the strongest absorption spectrum line of ammonia in the middle and far infrared band, completely free from cross interference of H2O, SOX, COX, CXHY, NOX and other molecules. 2. No on-site dimming correction is required: the original MIR-SHORTTM ultra-short optical path gas absorption cell avoids the trouble of frequent light maintenance, and the optical-mechanical structure is not affected by the thermal deviation of high temperature environment. 3. High reliability and easy maintenance: the absorption tank has high luminous efficiency, and the high dust and high saline-alkali crystallization of industrial flue gas will not affect the accuracy of the system. It also completely avoids the high maintenance requirements of precision equipment such as long optical path multiple emission absorption cell. 4. Small direct measurement error: direct measurement of ammonia molecular spectrum ensures high accuracy, and there is no conversion problem of pretreatment system of indirect analysis technology. 5. Low comprehensive operation and maintenance cost: the pretreatment system is simple, the whole process of hot and wet heat tracing and sampling, without additional processes such as condensation water removal, conversion furnace, dilution sampling, etc. Technical parameters: Measured component: NH3 Range: 0~20/50/100/200 ppm Detection limit: 0.1 ppm Detection accuracy: ± 0.1 ppm (1s integration time) ± 0.01 ppm (100s integration time) Response time: 15s (depending on sampling length and flow) Linear error: ± 1% F.S Zero and span drift: ± 2% F.S Analog output: 1 channel of 4-20mA output (isolated maximum load 750) Digital output: RS232/RS485 Wireless output: 4G or WIFI Data storage: USB interface Sample gas temperature: room temperature or high temperature (up to 450 ° C) Treatment method: hot wet sampling Sampling flow: 0.25-5 L/min Tracing temperature: 60 ° C~230 ° C adjustable Dust requirements: filtration accuracy ＜ 5um Power supply: AC 220V 50Hz<1.0 kW Ambient temperature: - 20 ° C~55 ° C Protection grade: IP54 Size and weight of main engine: 486 × one hundred and seventy × 340 mm3 (long × wide × Height)~10 kg
