GNL-400 trace hydrogen analyzer

Setting upper and lower alarm values arbitrarily during the measurement range.

1. Introduction GNL-400 trace hydrogen analyzer adopts imported high-performance electrochemical 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.

2. Features Latest trace hydrogen tester Big LCD screen, concise menu Connecting to the printer to print the hydrogen concentration in a certain terminalAutomatic data storage in a certain interval time, and browsing data at any timeIt can achieve two-way communication by connected to a computer via the standard RS232 interfaceSetting upper and lower alarm values arbitrarily during the measurement range. Calibrating by standard gas0-10mA or 4-20mA electrical current output
