ZA-3002 Portable Intelligent Gas Purity Analyzer

Brief introduction ZA-3002 Portable Intelligent 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. It can monitor gas purity. Main features Thermal conductivity sensor with high stability and high precisionFull-range temperature compensation, quick response, high precision and steady performanceReal-time curve displayOperation and control by color touch screenStorage and printing of measured dataIntelligent display of electricity quantity and intelligent charging protectionTechnical parameters Single extent analyzer H2 0 100% (background is single gas or composite gas with steady thermal conductivity value, such as air, N2, O2,CO2, etc. ) CO2 0 100% (background gas is single gas or composite gas with steady thermal conductivity value, such as air, N2, O2, H2, etc.) He 70 100% (background gas is single gas, such as air, N2, O2, etc.) O2 95 100% (background gas is H2) Other two kinds of gases with relatively big difference of thermal conductivity 0-100% (refer to table of thermal conductivity value of gas) Precision ±0.2% 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 over 6 hours (with automatic charging protection) Digital output RS232 USB2.0 Enviroment temperature -20 50°C Humidity ≤95% Dimension 273 mm×257 mm×143 mm Weight about 5.8Kg Legend 1.
