CO₂ (R744) leak detector with precise NDIR infrared sensor, specially designed for leak detection on refrigeration and heat pump systems.
The CENTER-389 is an electronic leak detector specially designed for precise CO₂ (R744) leak detection in refrigeration and heat pump systems.
It uses a highly selective and accurate Non-Dispersive Infrared (NDIR) sensor to ensure fast and reliable CO₂ detection, even at low concentrations.
The device offers three adjustable sensitivity levels to adapt to various environments.
With automatic and manual detection modes, and a RESET function based on ambient concentration, it minimizes false positives.
Color-coded LED indicators provide intuitive leak presence feedback.
Thanks to its 40 cm probe, it allows easy inspection of hard-to-reach areas.
It is powered by a rechargeable Li-ion battery with 7 hours of autonomy for extended use on site.
