GasCheck Tesla Helium Leak Detector

Handheld helium leak detector for MRI scanner maintenance.

GasCheck Tesla is a highly sensitive helium leak detector designed for effective use within high magnetic fields found around the outside of Magnetic Resonance Imaging (MRI) scanners. The instrument’s advanced micro thermal conductivity sensor provides rapid, accurate measurement of helium leaks down to ultra-low levels.

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

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

The GasCheck Tesla helium leak detector automatically zeros to the ambient air around it when switched on, and is ready to detect immediately. The instrument’s easy to usegraphical interface and intuitive keypad allows simple function, selection, and adjustment.

The probe is designed to get into the smallest of places and is typically moved along a joint or weld seam a few centimetres per second, enabling fast detection of all possible leak paths.

This portable instrument provides simple one-handed operation.
