GasCheck Tesla – Helium Leak Detector

Portable He Leak Detector

The GasCheck Tesla portable helium leak detector is a highly sensitive He leak detector designed for effective use within high magnetic fields found around the outside of Magnetic Resonance Imaging (MRI) scanners. MRI scanners reply on liquid helium, so its important to detect any helium leaks with our portable detector.

GasCheck Tesla portable gas leak detector can be used on an MRI scanner whilst in operation, meaning interruptions to the machinery are avoided. Helium leaks are detected quickly reducing cost, wastage, and downtime of the machinery.

The GasCheck Tesla portable helium leak detector provides stable, repeatable readings. The instrument’s LCD display, LED indicator and audible sounder clearly detect & indicate the helium leaks present.

The portable helium leak detector automatically zeros to the ambient air around it when switched on, and is ready to detect immediately. The portable detector has an easy to use graphical interface and intuitive keypad that allows simple function, selection, and adjustment.

Ultimate performance

  • Operates effectively to detect He within a magnetic field
  • Detects the smallest of He leaks down to ultra-low levels
  • Small internal flow rate provides maximum He sensitivity
  • Fast, accurate He leak detection
  • Reliable, stable, repeatable He readings

Ultimate safety

  • Large, clear LCD back-lit display for easy viewing of results
  • Easy to use graphical icon menu
