LM100H
Handheld Explosion-Proof Laser Hydrogen Chloride Detector
Handheld TDLAS-based laser HCl detector for remote detection at distances of up to 10 m. The device features IP65 protection, Ex certification, and Bluetooth data sharing for field operations.
LM100H In Brief
Hydrogen chloride (HCl) is widely used across industries and requires reliable monitoring due to its hazardous nature. Routine and unplanned inspections demand a solution that combines performance with portability. The LM100H meets these requirements, detecting HCl at distances of up to 10 m using TDLAS technology and enabling safe inspection without approaching the leak source. The device is Ex-certified, IP65-rated and supports Bluetooth data logging and transfer for efficient field use.

How LM100H works
The LM100H uses TDLAS (Tunable Diode Laser Absorption Spectroscopy) technology to provide precise methane detection with a tunable diode laser.
- Step 1The laser emits a narrow beam of light at a wavelength that matches the HCl absorption profile.01
- Step 2As the beam passes through the gas, some of the light is absorbed by the HCl molecules.02
- Step 3The laser beam is reflected off the ground or other surfaces.03
- Step 4The sensor captures the reflected light.04
- Step 5The system calculates the HCl concentration by analyzing how much light is absorbed.05

Why hydrogen chloride detection matters
Detecting hydrogen chloride leaks is critical due to its corrosive nature and associated health hazards. Even at low concentrations, it can irritate the respiratory tract, eyes, and skin, while prolonged exposure increases health risks and accelerates corrosion of equipment and infrastructure. Early detection helps limit worker exposure, reduce corrosion-related failures, and ensure compliance with environmental and safety regulations.
FAQ
Honest answers to important questions
No, each device is designed to detect a specific gas. This ensures a 100% detection rate for HCl leaks, and not for any other gas.
Laser radiation is completely safe.
Yes, the instrument works in all weather conditions.
No, there is no impact.
No. The detector contains a reference cell with methane inside and calibration is performed at each start-up and during operation.
It works remotely. There is no direct contact with the hazardous environment.
Yes, because glass transmits near-infrared radiation well.
