GasCheck Tesla Handheld Helium Leak Detector

Handheld Helium Leak Detector for MRI Scanner Maintenance

The Ion Science 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.
The instrument 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.
The GasCheck Tesla provides stable, repeatable readings. The instrument's LCD display, LED indicator and audible sounder clearly indicate the helium leaks present. GasCheck Tesla automatically zeros to the ambient air around it when switched on, and is ready to detect immediately. The instrument's easy to use graphical interface and intuitive keypad allows simple function, selection and adjustment.
Handheld and portable, the GasCheck Tesla provides simple one handed operation. 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.
