The new PULSAR NDIR Multi-gas analyser from Signal Group has been upgraded to provide the company’s best ever performance specification. With ultra-low drift it is ideal for low range applications and high accuracy measurement. The unique design of the detector prevents cross-sensitivity to other gases and also removes the risk of contamination by particulate matter. As a result, this instrument is ideal for a wide range of industrial applications.
