Product description
ZA-3002 portable H2 gas purity analyzer for power plant Brief Introduction ZA-3002 portable gas purity analyzer adopts thermal conductivity sensor with high stability and high precision. According to the difference in thermal conductivity of gas, it can accurately and quickly measure the content of random one gas of two mixture gases. Unique technique of wide-range temperature compensation is adopted, so as to guarantee the measurement precision of instrument. Main Features u Thermal conductivity sensor with high stability and high precision u Full-range temperature compensation, quick response, high precision and steady performance u Real-time curve display u Operation and control by colorized touch screen u Storage and printing of measured data u Intelligent display of electricity quantity and intelligent charging protection Technical Parameters Measurable gas: H2(N2),He(N2),CO2(N2) &etc. Two kinds of gases known and the difference of thermal conductivity coefficient of them is large. Range: 0~100% (optional) Precision: ±2%F.S Repeatability: ≤±1%F.S Response time: T90≤15s Flow: 0~2SCFH(1SCFH≈500mL/min) Working flow: 0.8~1.2SCFH Power supply: built-in lithium battery (8000mAh), AC-DC Time of usage: >10 hours Charging time: >6 hours (with automatic charging protection)) Digital output: RS232 USB2.0 Environment temperature: -20~50℃ Humidity: ≤95% Dimensions: 273 mm×257 mm×143 mm Weight: About 5.8KG Attached Table :thermal conductivity coefficient of different gases(>120℃)
