Stainless steel test chambers in a laboratory rack for emission testing

Test Chamber Systems

The determination of formaldehyde and VOC emissions from wood-based materials, construction products and furniture is a core competence of the EPH for many years.

As accredited test body for emission testing, the EPH provides not only professional know-how but also technical equipment in terms of emission test chambers and gas analysis systems.

These test systems are especially characterised by an easy operability and a layout adapted perfectly to customer`s needs as well as by an attractive price. Among others, the systems are established in the wood-based materials, binder- and furniture industry and at testing institutes. Emission testings can be conducted according to several test procedures.

We are pleased to support you in course of R&D or product surveillance, to validate your system by appropriate comparison tests and to train your laboratory staff.
