Signal Group’s involvement in engine emissions testing dates back to the very beginning of the company in 1977. Since that time, a commitment to research and development has assured the provision of analysers featuring the latest advances in technology, designed to test to the latest Standards.

The new S4 analysers are particularly well suited to engine testing. The instrument screen has been replaced by a detachable tablet so that the operator can control the analyser via Bluetooth from outside of the test cell. In addition, the analysers have Ethernet capability so that users can connect with their instruments from anywhere and at any time.

In contrast with many competitive systems, the Signal analysers are able, if necessary, to operate completely independently, which is a major advantage during service operations and when an analyser is off-line for any reason.

Each analyser is designed to meet the latest USEPA 1065 and EURO 6 requirements.
