Product Description Product DescriptionNK-550A UV gas analyzerNK-550A UV gas analyzer), this analyzer can measure the concentration of SO2, NO, NO2, O2, NH3, Cl2, O3, H2S, CH3I and other gases, the detection limit is up to 1mg/m3, has the characteristics of high measurement accuracy, high reliability, fast response time, wide range of application, and other indicators meet or exceed similar foreign products. Fully qualified for ultra-low emission monitoring occasion measurement technical index requirements.Product characteristicsThe detection limit of SO2, NOx and other gases reaches 1mg/m3 (15m optical path). Compared with NDIR, the measurement accuracy is completely unaffected by moisture and dust (vapor water does not absorb in the ultraviolet band, while liquid water and dust have non-selective absorption of ultraviolet light, which is a slow change in the spectrum), low detection limit, and small temperature drift. Range ratio up to 10:1, and support automatic range switching;The light source is pulsed xenon lamp with a lifetime of 109 times. According to 3 times/second calculation, the service life is up to 10 years;No optical moving parts, not affected by vibration;NO and NO2x are measured directly in ultraviolet wavelengths without the need for a NO2→ NO converter. NO and NO2 are absorbed in the ultraviolet band. By measuring NO and NO2 at the same time and accumulating NOx, we can save the cost of purchasing NO2→ NO converter for customers, and improve the reliability of the system.White pool technology +DOAS+PLS technology, zero drift, small quantity drift;Automatic regulation spectrum technology, long maintenance-free cycle;The cross interference between the measured gases is small.Product characteristicsThe gas concentration is measured by ultraviolet absorption spectrum and chemometrics algorithm and displayed in real time. The concentration is output in real time by RS232, RS485 and 4-20mAZero calibration and range calibration of manual and automatic event triggers (such as timing time, external switch input, etc.) can be achievedSwitching and analog output/input can be flexibly configured to achieve good coordination with external control systemsEach gas (except O2) supports two ranges, which can be switched automatically, manually or externally, with a range ratio of 10:1Automatic spectral energy regulation is supported when the energy of the gas chamber lens is degraded due to sample gas pollutionSupport remote configuration and remote diagnosis analyzer through GPRSTechnical indexMeasurement technology: UV DOAS (, NO, NO2)Range:NO: 0~2000ppm(customizable)NO2:0~2000ppm (customizable)Linear error: ≤±1.5%F.S.Repeatability: ≤0.5%Zero drift: ≤±2%F.S. /7dRange drift: ≤±2%F.S. /7dResponse time: < 10s (T90)Preheating time: No preheating is requiredSample gas flow requirements: (0.5~2) L/min, fluctuation < 25%Sample gas pressure requirement: current ambient pressure ±0.1barSample temperature requirements: 0oC~50oCSample gas humidity requirements: no condensation (sample temperature)4-20mA Input port: Two, flexible configuration, 100 Ohm loadCommunication interface: RS485 (support Modbus protocol)Protection class: IP42Operating temperature: -10oC~+40oCWorking humidity: 0~95%Overall dimensions: 177mm (H) ×483mm (W) ×434mm (D)Voltage/Power: 220VAC±10%/ about 220WWeight: about 12kg Detailed Photos Product ParametersItemName Model and descriptionQuantity1Networked gas chromatographThe advanced carrier gas protection and gas path protection functions realize automatic gas path fault protection, automatic ignition, automatic flame-out, automatic gas path opening, and achieve one-key start.
