We prepare test gases for calibrating gas measuring equipment in our own compressed gas filling installation. By using modern production techniques and analytical methods we ensure that our products are of the best quality.

In German coal mining, which is subject to strict safety regulations, DMT test gases are almost exclusively used. But it is not only in mining where our products are put to use, also coking plants, waste disposal operators, instrument and equipment manufacturers and fire services apply our test gases.

When test gas is to be applied one of the most important prerequisites is that it is available at short notice. Production, filling and analysis of most of the test gases can be carried out within just a few working days, and in certain cases we can provide what is required even quicker. If required we can arrange dispatch, collection, servicing, maintenance and pressure testing of your test gas cylinders.

We have been involved with gas measuring techniques for almost one hundred years. DMT has a national testing centre approved by the mining authorities and works closely together with the test laboratory EXAM GmbH, which has European approval.
