Premium electronic leak detector for all gases (HFC, HFO, HC, N₂/H₂), with color display, ultra-sensitive MOS sensor and Li-ion battery.
The LT-300-PRO2 is a high-end leak detector designed to meet the needs of HVAC and refrigeration professionals.
Equipped with a MOS-type semiconductor sensor, it provides ultra-precise detection of refrigerants (HFC, HFO, HC) and hydrogenated nitrogen (N₂/H₂), with maximum sensitivity < 3g/year. It offers two operating modes (manual and automatic), three sensitivity levels, and a Reset function for adapting to various environments.
Its large color screen with graphical display allows instant reading of leak levels. An LED at the probe tip provides immediate visual alerts. It includes a test vial for performance verification, a long-life rechargeable Li-ion battery, and a premium rugged case for transport.

Yes, the LT-300-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-300-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.
