GNL-B3/YF1 Process Trace Oxygen Analyzer

Introduction New product---GNL-B3/GNL-YF1 analyzer (only for wave soldering oven and reflow soldering oven) breaks through traditional magneto mechanical measurement mode and measures oxygen concentration without benchmark gas by adopting conversion ion current with the world advanced technology as measurement principle. It has observable characteristics of long calibrating period, high precision, small appearance and low power consumption.Features * New pattern, long-life, conversion ion current tester with fast response and high sensitivity * Concise menu, simple operation * Checking the sensor working state automatically and unique double-line working change mode extending the sensor's life * Setting upper and lower alarm values freely during the measure ranges * 4-20mA or 0-5V DC signal outputs * It can achieve two-way communication by connected to a computer via the standard RS232C or RS485 interface.Technical Specifications Measure Range: 0-10ppm, 0-100ppm, 0-1000ppm, 0-25% O2; Auto-ranging Accuracy: ±0.5ppm in the range of 0-10pppm; ±1ppm in the range of 0-100pppm; ±2ppm in the range of 0-1000pppm; ±1% in the range of 0-25% Stability: Zero drift ≤±1%FS/7d Span drift ≤±1%FS/7d Contact Capacity: 125VAC 0.3A, 110VDC 0.3A, 30VDC 1A Repeatability: ≤±1% Response Time: 90% of FS reading ≤10 seconds Sampling System: Film sampling pump or inner minus pressure system Sample Gas Flow: 200 300ml/mim Ambient Temp.: -10 +50ºC Power Supply: 85V-265V AC, 50Hz±5% Sensor Life: 36 months at 25ºC and 1 ATM Warranty: 12 months analyzer; 12 months sensor Weight: 3kg Installation Dimension: 133mmx270mmx300mm (GNL-B3) (WxHxD) 125mmx200mmx300mm (GNL-YF1)Applications It can be used to measure the oxygen concentration in the fields of magnetic materials, high temperature sintering furnace, the electronics industry protective gas.Order knowledge Measure range Tested gas pressure Gas composition and impurity.
