How do I know if I need to send my helium leak detector for repair?

Annual preventative maintenance is recommended to ensure proper operation and prevent issues resulting in larger repairs. If the unit is not functioning as expected or an error message is present contact us for troubleshooting or to send in for repair.

How do I know if my turbopump needs to be serviced? 

If your turbopump is not coming up to proper speed or not pumping to the correct pressure, it may need service. Also if the turbo is making a loud whining or scratching noise it may require service.

How do you want me to ship my product to you?

Leak detectors are very sensitive electronic equipment and should be securely boxed, banded to a skid, and shipped by a freight service or courier.

Turbo pumps should be packaged in a sturdy box or shipping container and shipped via FedEx Ground or freight service
