Product DescriptionBLA-820 Ultra-Low Range Flue Gas AnalyzerIntroduceThe BLA-820 Ultra-Low Range Flue Gas Analyzer, developed by our company based on decades of expertise in UV absorption spectroscopy for ultra-clean emission applications in coal-fired and gas-fired power plants, is a multi-pass optical path gas analyzer. Utilizing UV differential absorption spectroscopy (DOAS) and chemometric algorithms (PLS), it measures concentrations of gases including SO2, NO, NO2, O2, NH3, CO, CO2, Cl2, O3, H2S, HCl, CH3I,and CH2O, with performance metrics that meet or exceed international standards. Additionally, our flue gas analyzers feature proprietary infrared modules for CO detection, which outperformelectrochemical methods with superior accuracy, faster response, and enhanced reliability—effectively addressing the short lifespan issue inherent in electrochemical technologies.The analyzer can measure multiple components at the same time (customized).Technical specification(Regular Range)Gas rangeSO2, NO, NO2, NOx,CO, CO2, O2, CustomizedLinearity±1.5%F.S.Indication error<5%Repeatability<±0.5%F.S.Zero drift<±2%F.S./7 daysSpan drift<±2%F.S./7 daysWorking temperature-10-50℃Responsible time<10 secondsPower 220V±20%VAC/100WCommunication protocol232/485/Mod busSample gas temperature0-50℃Warm-up timeNo warm-up timeDetailed physical product imagesPackages The size and measurement of the gas can be customized according to the size of the detection space and the different gases detected.We use fumigation free plywood box packaging, meet all export standards such as sea, air and land transportation.Main functions (1)Utilizes UV absorption spectroscopy and chemometric algorithms to measure gas concentrations with real-time display. (2)Data is transmitted via RS232, RS485, and 4-20mA for instant output. (3)Enables manual and automated event-triggered calibration (including time-based triggers and external switch inputs) for zero and range adjustments. (4)Flexible configuration of switch outputs and analog inputs ensures seamless integration with external control systems. (5)Each gas type (excluding O2) supports dual-range measurement (large/small), with automatic, manual, or external-triggered switching between ranges up to 10:1 ratio. (6)Automatic spectral energy adjustment when sample contamination causes energy attenuation in gas chamber lenses. (7)Supports remote configuration and diagnostic analysis through GPRS.DebuggingFor each Gas analyzer before ex-facotry excepting doing strictly inspection, we will all let it operating for at least 3 days to confirm all software has no problems.Manufacturing InspectionCertificateWe have more than 2000 square meters manufacturing factory located in Hangzhou and Xian city.We are a high-tech enterprise specializing in the research and development, production and sales of online monitoring instruments in the fields of environmental monitoring, industrial control and industrial safety.We have more than 200 full-time R&D staff, among whom more than 20% have master's degree or above.
