PLD pump suction full range laser portable instrument

PLD pump suction full range laser portable instrument adopts advanced TDLAS technology and uses semiconductor laser diodes as the light source, with good monochromaticity and zero cross interference. Adopting unique FOS technology, the instrument comes with a reference chamber inside, which can lock the center wavelength of the laser in real time, improving the accuracy and stability of system measurement; By using a multiple reflection laser cavity, the effective optical path of the laser is greatly increased, thereby improving sensitivity and detecting even small leaks.

1. Leakage point fixed in seconds: high flow pump suction, achieving TDLAS positioning in seconds

2. Good selectivity: Adopting advanced TDLAS technology and using semiconductor laser diodes as light sources, it has good monochromaticity and achieves zero cross interference

3. Anti temperature drift: Using unique FOS technology, the instrument comes with a reference chamber inside, which can lock the center wavelength of the laser in real time, improving the accuracy and stability of system measurement; The gas sample contained in the reference gas chamber, a part of the laser beam passes through the reference gas chamber, and the center wavelength of the laser is locked by detecting the information of the reference light path.

5. Long lifespan: The key components used are from well-known foreign manufacturers, with good reliability. Using semiconductor laser diodes as light sources has a long lifespan, generally over 10 years. High sensitivity infrared detector, good stability, anti drift.

6. Full range detection: adjustable range, optional automatic or manual unit switching

Mainly used for courtyard gas pipeline inspection, there are three application forms: handheld, manual push, and electric.
