High-sensitivity electronic leak detector (<3g/year) for HFC, HFO, HC and N₂/H₂ gases, with semiconductor sensor and adjustable sensitivity.
The LT-100-PRO2 is an electronic leak detector designed for the rapid identification of refrigerant gas leaks (HFC, HFO, hydrocarbons – HC, and hydrogenated nitrogen – N₂/H₂).
Thanks to its microprocessor-controlled semiconductor sensor, it ensures highly accurate leak detection (<3g/year) with excellent stability and durability (up to 500 hours of operation).
It offers two detection modes – automatic or manual – with three adjustable sensitivity levels, and ambient auto-calibration to prevent false alarms.
Visual and audible alarms enable fast leak location. Its redesigned suction head enhances gas capture, and it comes in a sturdy case ideal for field operations.

Yes, the LT-100-PRO2 is equipped with a heated diode semiconductor sensor that can detect both standard refrigerants and hydrogenated nitrogen (N2H2). It is also suitable for detecting flammable refrigerants such as R290.
When automatic mode is activated, the device recalibrates every 5 seconds according to the concentration at the detection head. This mode, also called “search” mode, allows the device to ignore ambient noise by recalibrating itself. As a result, the device will only respond to concentrations above the ambient level (i.e., close to the leak source).
Once the leak area is identified, manual mode can be used. In this mode, sensitivity can be adjusted across three levels (low, medium, high), allowing precise detection at the exact leak location without intermediate recalibration. The leak can be tested multiple times to confirm its presence.
Yes. As required by current French regulations, the LT-100-PRO2 complies with the NF EN 14624-2020 standard.
Yes, provided it is not operated in an explosive atmosphere. The ambient atmosphere must be checked with an explosimeter, such as the YT-1200H-S R290, to ensure that the lower explosive limits (LEL) are not exceeded.
If the LEL is approached, the area must be ventilated to dilute flammable vapors and reduce the concentration below 25% LEL.
