Polycyclic Aromatic Hydrocarbons (PAHs) are a group of over 100 different chemicals that are known to be formed typically during incomplete combustion of organic matter at high temperature. Their major sources in the atmosphere include industrial processes, vehicle exhausts, waste incinerations, and domestic heating emissions. Due to their carcinogenic/mutagenic effects, 16 PAHs are currently listed as priority air pollutants.

A wide variety of products that are used in our indoor environments may emit harmful substances, raising health and safety concerns in homes, offices, public places and vehicles. There is increasing demand to reduce VOC emissions from indoor sources, backed by European legislation. REACH regulation is a European initiative for the Registration, Evaluation, Authorisation and Restriction of Chemical Substances. It was implemented to protect human health and the environment from harmful emissions of chemicals into the air we breathe. The REACH regulation places the responsibility on manufacturers and importers to test their products and provide safety information to the purchaser, end user or consumers.

Engine and vehicle emissions testing involves complex routines and audit regimes to meet with exacting modern legislation. The methods for measuring gases are also prescribed by the relevant authority and so you might imagine that the equipment for emissions testing is all the same. Signal take a different approach to our competitors. By designing bespoke systems from a selection of standard modules, we supply all the equipment and features you require, but nothing that you don`t. This makes our systems the most cost effective solution, particularly when upgrading or for non-standard combination testing
