Infrared analyzer FV-4200- (CO+CO2):Instrument Featuresl Thin-film microphone detector with high sensitivity, long life and good reliability;l The detector adopts the structure of front and rear air chambers, which greatly improves the selectivity of the instrument and has little cross-interference;l Adopt amplitude modulation technology, strong common mode rejection ability, small zero drift and good stability;l Fully sealed optical path, not affected by ambient atmosphere;l Encapsulated infrared light source, high stability;l The gold-plated measuring chamber has strong corrosion resistance;l Large-screen LCD display, full Chinese operation menu, man-machine dialogue, automatic prompt operation steps;l Automatic detection of light source voltage, background reference voltage and other working parameters;l Dual range automatic conversion (option), computer software linearization processing;l With two sets of alarm contact output, the upper and lower limit alarm points can be arbitrarily set within the full range;l With timing automatic storage function, you can view the stored data at any time;l With the function of paperless recorder, it can automatically record the change curve of the measured gas concentration with time;l With fully isolated 0~10mA or 4~20mA standard signal output;l With RS-232 communication port, it can connect serial printer or realize two-way communication with computer.Main technical characteristicsMeasurement object, minimum measurement range and range specifications2.1 Measurement object, minimum measurement rangeCarbon monoxide CO2: 0~0.002% (20 ppm)Carbon dioxide CO2: 0~0.002% (20 ppm)Methane CH4: 0~0.01% (100 ppm)Sulphur dioxide SO2: 0~0.05% (500 ppm)Nitric oxide NO: 0~0.05% (500 ppm)2.2 Standard range (%VOL)0~0.02; 0~0.05; 0~0.1; 0~0.2; 0~0.5; 0~1; 0~2;0~5; 0~10; 0~15; 0~20; 0~30; 0~40; 0~50;2.3 Special range specificationsa. Other measurement objects and their ranges other than CO, CO2, CH4 shall be negotiated by the user and the design department of our company.b. Special order is required for ranges below 200ppm or above 50%.2.2 Main technical performance indicatorsZero drift: ≤±1%FS/7dRange drift: ≤±1%FS/7dLinearity error: ≤±1%FSRepeatability: ≤0.5%Output fluctuation: ≤±0.3%FSResponse time: related to the length of the measuring air chamber, the maximum T90<10 secondsPreheating time: <0.5hAmbient temperature: 5~45 ºCAmbient humidity: ≤90%RH2.2 Gas sample conditionsGas sample temperature: 5~40 ºCSample gas pressure: 2~50 KpaSample gas flow: 200~1000ml/minMoisture content: dry before entering the instrumentDust content: remove dust and mechanical impurities before entering the instrument3. Trace water analyzer FV-4200-P2O5FV-4200-P2O5 analyzer adopts P2O5 electrode sensor and adopts the principle of electrolysis, which can continuously, quickly and accurately test trace water in gas. The principle of the P2O5 electrode is: the electrode absorbs the gas moisture, electrolyzes the water into H2 and O2, and the content of the water molecules can be known from the current consumed. The corrosion-resistant electrode is a washable P2O5 electrode. It is mainly made of strong corrosion-resistant material as the base material. The base material is wound with equidistant platinum wires, and then a removable corrosion-resistant body is installed.It is suitable for trace water detection in petroleum, chemical industry, electric power, metallurgy and medical oxygen.Parameter performance:Measuring range: 0-10/100/1000ppmMeasurement accuracy: ≤±2%FSFlow rate: 400ml/minRepeatability: ≤0.5%Output fluctuation: ≤±0.3%FSResponse time: T90 < 3 secondsPreheating time: <0.5h
