Nolek SniffIT X1® Helium & Hydrogen Sniffer

TQC as sole UK agent and distributer for Nolek are pleased to announce the new SniffIT X1 portable helium and hydrgen sniffer leak testing device.

SniffIT X1® is ergonomic and the smallest high quality instrument on the market, it weighs approximately 300g (0.66 lbs).

The smallest detectable levels of Helium and Hydrogen with SniffIT technology® is 1x10-6 mbar.l/s, making the technology one of the most sensitive in the marketplace today.

The flexibility to detect both Helium and Hydrogen makes SniffIT X1® independent of the tracer gas used for leak detection, and is the only one of its kind.

With SniffIT technology® the sensor never gets saturated and consequently the instrument has no variable costs unlike most alternatives. At the same time it has instantaneous reaction time and no start up time, just push the ON button and start sniffing.


SniffIT X1® is built and developed to meet four criteria:

SIMPLE: not operator dependent, simply press ON and if Helium or Hydrogen leaks from a product it is shown on a LED bar. The color on the LED scale changes depending on the leak rate detected.

MOBILE: It is not bigger than a human hand, weighs 300g (0.66 lbs) and has 10 hours of battery capacity.

ACCURATE: SniffIT gives very accurate results based on a reliable unique technology.

AFFORDABLE: SniffIT X1® is the least expensive high quality sniffer on the market, less than half the price compared to alternatives and there are no hidden variable costs. performance,

SniffIT X1® is the most revolutionary product ever launched within the leak testing and detection industry. It is smaller, more accurate and less expensive than all other comparable alternatives making the decision to invest in leak detection simple.
