Ntroduction
GNL-400F percent hydrogen analyzer adopts thermal conductivity sensor with latest micro computer technology. It has such functions of LCD display, upper & lower alarm, signal output and relay contactor alarm output. And can be used to measure the hydrogen concentration in air, nitrogen, oxygen and argon. Features Latest trace hydrogen tester Big LCD screen, concise menu Connecting to the printer to print the hydrogen concentration in a certain terminal Automatic data storage in a certain interval time, and browsing data at any time It can achieve two-way communication by connected to a computer via the standard RS232 interface Setting upper and lower alarm values arbitrarily during the measurement range. Calibrating by standard gas 0-10mA or 4-20mA electrical current output Technical Specifications Measure Range: 0-5%,0-10%,0-20%,0-30% H2 Accuracy: ±2% in FS range Repeatability: ±0.5% Response Time: 90% of FS reading ¡Ü30 seconds Contact Capacity: 250VAC/1A Signal Output: 4-20mA DC or 0-10mA DC Power Supply: 220±10% VAC, 50Hz, power loss¡Ü15VA Working Temp.: -10ºC~+60ºC Sample Gas Flow: 200~400ml/mim Sample Gas Pressure: 0.05MPa ¡ÜInlet pressure¡Ü0.2Mpa Warranty: 12 months analyzer; 12 months sensor Installation Dimension: 133mmx133mmx250mm (WxHxD) Weight: 2.5kg Applications It can be used to measure the trace hydrogen concentration in the fields of nitrogen separation from air, chemical process, magnetic materials such as high temperature sintering furnace gas protection, various mixed gases, and so on.
