Leak Testing

As part of the most convenient, economical and quality service platforms for portable nuclear density gauge services, Qal-Tek offers online leak testing as well as leak test kit mail in services.

Our team is capable of performing leak tests onsite while performing calibration and repair services. While our team is onsite we will collect, analyze and document your entire inventory of gauges requiring leak tests, OR just the ones that are due OR we can leave leak test kits behind for you to return when the leak test kits are self performed and ready for analysis.

Unlike our competitors, and to better serve our clients, we do not charge upfront for our leak test kits! Simply let us know how many kits you need and we’ll either mail them out or leave them after our onsite service. Send them in and you only pay when they are processed. No more paying for lost leak test kits.
