LM100A
Handheld Explosion‑Proof Laser Ammonia Detector
Handheld TDLAS-based laser NH3 detector for remote detection at distances of up to 20 m. The device features IP65 protection, Ex certification, and Bluetooth data sharing for field operations.
LM100A In Brief
For both routine and unplanned ammonia inspections, operators need a solution that combines performance with portability. The LM100A laser detector enables remote ammonia detection at distances of up to 20 m using TDLAS technology, providing an immediate response and allowing safe inspection without approaching the leak source. The device is Ex-certified, features a robust IP65-rated housing, and supports Bluetooth data logging and transfer for efficient field use.

How LM100A works
The LM100A 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 NH3 absorption profile.01
- Step 2As the beam passes through the gas, some of the light is absorbed by the NH3 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 NH3 concentration by analyzing how much light is absorbed.05

Why ammonia detection matters
Ammonia is widely used in industry and presents significant health hazards, being corrosive and highly irritating to the skin, eyes, and respiratory system. It has an IDLH level of 300 ppm and an OSHA permissible exposure limit of 50 ppm over an 8-hour shift. Even at low concentrations, it can cause respiratory irritation, while higher levels pose serious health risks. As a commonly used refrigerant and chemical feedstock, ammonia leaks can also lead to equipment damage and process disruptions.
FAQ
Honest answers to important questions
No, each device is designed to detect a specific gas. This ensures a 100% detection rate for NH3 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.
