Designed for Portability

Maintain the integrity of your helium refrigeration system. Save money and downtime by finding leaks quickly and efficiently on your MRI scanner. The highly sensitive Tesla, an inherently safe leak detector, is designed to be used on an MRI scanner while it is running so that daily operations do not have to be interrupted while diagnosing possible helium leakage and loss. Fitted with a large back lit LCD, the display shows unit setting and numerical readout, even in dark, confined spaces.

Handheld and portable, the 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 centimeters per second, enabling fast detection of all possible leak paths.

Accurate Reading

When searching for leaks the unit can easily be set into auto-range, giving the maximum sensitivity when required. The GasCheck TESLA uses a robust micro thermal conductivity sensor to detect any gas providing it is different from air or nitrogen. Calibrated for helium, the unit also has multiple gas selection including Ammonia, Argon, Butane, Hydrogen, SF6 and some refrigerants.
