Laser micro water analyzer

The laser gas analysis analyzer is a high-precision, low-temperature drift trace water analysis instrument based on tunable laser absorption spectroscopy technology. Through a gas absorption cell with multiple reflections, it can provide an effective optical path of nearly 3 meters and achieve a detection limit of nearly 0.1 ppm. The integrated design of laser, detector and air chamber greatly reduces the interference of air background on measurement. Meanwhile, the compact absorption tank structure and anti adsorption treatment on the inner wall of the gas chamber effectively improve the response speed of trace water measurement.

Natural gas, petrochemicals, steel smelting SF6、 Analysis and control of water dew point in fields such as lithium batteries.
