Product Description
LGT-180 online gas analyzer is a 19" panel mounted type tunable laser gas analyzer for industrial online analysis and environmental on-line monitoring. The analyzers combine TDLAS technology and multiple reflection long optical path technology that can analysis a variety of gas including O2 , CO2, NH3 , H2S, CO , CH4 , H2O. Reflected light can be customized according to the working condition demand, the measured gas concentration ranges from constants to the trace.

1. 19 inches 3U panel mounted chassis, exquisite construction
2. TDLAS eliminates cross-interference of background gases
3. Multiple return optical path up to 25 meters, obviously lower detection limit
4. No optical moving parts, high reliability, not affected by field vibration

1. Response Time ≤5s (T90)
2. Calibration Cycle ≤2 times/ year
3. I/O mode: 4-20mA, RS485/RS232/GPRS
4. Purge gas: 0.3MPa ~ 0.8MPa N2, clean air
