CI-PC21 infrared gas analyzer
Brand CHANG-AI
Certification N/A
The selective infrared absorption of gas molecules is the design basis of the infrared gas analyzer. SO2, NOX, CO2, CO, CH4 and other polar molecules have permanent electric dipole moment, so they have vibration, rotation and other structures. Splitting energy levels divided according to quantum mechanics can be coupled with the long infrared radiation of the incident features to produce absorption, and different polar molecules have different spectral absorption bands; Application range: It is widely applied in gas analysis of petroleum, chemical industry, metallurgy, building materials, light industry and other various furnaces, kilns or flues and it is a reliable monitoring tool for environmental monitoring, biological engineering, health care and other scientific research work. Product features: 1. Specially designed gas chamber absorber ensures strong anti-interference ability of narrow band pass filter and high detection accuracy; 2. It has highly stable infrared source and the receiver is under constant temperature control, ensuring great instrument stability; 3. Measuring gas chamber mirror is gold-plated, resistant to corrosion; 4. Isolated analog signal output allows free setting of 4-20mA/ 0-20mA/ 0-1V/ 0-5V/ 0-10V/ 1-5V analog output mode; 5. Alarm function: when the gas concentration deviates from the alarm value, an alarm will be given, and the alarm value can be arbitrarily set within the full scale range; 6. RS485 (standard)/ RS232 (optional) applied Ordering instructions: 1. Gas circuit connection: A. φ6 hose connection (standard) B. 1/4"-φ6 stainless steel ferrule connection C. 1/8"-φ3 stainless steel ferrule connection 2. Filter: GF2800, AF2000; 3. Measured gas component and measurement range; 4. Pressure of measured gas: positive pressure, micro pressure or negative pressure; 5. Main components of measured gas, impurities, sulfide.
Technical Parameters:
1. Measuring principle: NDIR analyzer; 2. Measuring components: one or two components of NOX, SO2, CO, CO2, CH4, H2S are measurable and O2 can be added to each component; 3. Repeatability: ±1% FS; 4. Zero drift: ±1% FS/ 7d; 5. Full scale drift: ±1% FS/ 7d; 6. Linearity error limit: ± % FS; 7. Response time: T90 ≤ 60s (when the sample flow volume is 0.5L/ min); 8. Analog signal: 4-20mA, 0-20mA, 0-1V, 0-5V, 0-10V, 1-5V; 9. Maximum load: to be provided according to user requirements, no impact generated within the maximum load of 500Ω; 10. Environmental conditions: -10 ~ 45°C, not more than 80% RH; 11. Supply voltage: 85-264VAC 50/60Hz
