New NM Gas Tester

The new NM Gas Tester from Thermoseal Group is a simple lightweight solution for testing the concentration of gas in your IG units.

The NM Gas Tester features a slim-line sampling probe which is inserted into the sealed unit once filled with gas. Using the simple dial to control calibration levels and push-button operation, it quickly analyses gas levels and displays the finding on its easy-read digital display.

With an automatic switch off function as standard, this machine costs very little to maintain due to its long-lasting battery life and easy economical replacement of sensors.

Mark Hickox, Sales Director at Thermoseal Group, says “Most high performance double glazed sealed units are now filled with an inert gas such as Argon to increase thermal efficiency. Even the best sealed unit leaks gas throughout its lifetime, so it is imperative that you independently monitor the performance of your gas filling machine and production methods. It is also a prerequisite for EN1279 that you own and use a gas concentration tester.

The new tester is suitable for analysing the concentration of any inert gas in gas filled sealed units, and our range of products for gas filling are essential for glass manufacturers who want to meet the growing demand for gas-filled sealed units.”

The new tester is available for £799+VAT, while a NM test kit including hammer and punch for piercing the IG unit is also available for £22.95+VAT.
