Key features

Compact, lightweight and smart

The sniffer probe is not only extremely slim, it is also lightweight and ergonomically designed.
A colored status LED continuously informs the user about the operational readiness, measuring mode, and exceeding of the threshold value, while also indicating faults and warnings.

Low operating costs

The use of durable and long-life components minimizes costs throughout the entire life of the product.

User-friendly operation

The intuitive menu guidance makes it particularly easy to use the leak detector. The ergonomically shaped sniffer probe allows the device to be used even for long periods without operator fatigue.

High availability

The internal Cool Check reference leak can be exchanged quickly with the flick of a wrist.

Compatibility with modern communication systems

Optionally available fieldbus systems enable perfect integration into industrial networks.

No false alarms

The two-channel inlet allows leaks to be localized efficiently even with high background concentrations.

Other features 

  • Individual sniffer probes for CO2 and R600a/R290, and a universal Smart sniffer probe for halogen-based refrigerants are available.
  • The intuitive menu guidance makes it particularly easy to use the leak detector with a variety of configuration options.
  • Simple and automatic calibration or function testing is carried out by inserting the sniffer tip.
  • The wide variety of sniffer tips ensures efficient leak detection even in locations that are difficult to access.
