The latest PULSAR NDIR Multi-gas analysers have been developed to deliver outstanding levels of performance. With ultra-low drift they are ideal for low range applications and high accuracy measurements. The unique design of the detector prevents cross-sensitivity to other gases and removes the risk of contamination by particulate matter, so the instrument is ideal for a wide range of applications.
Employing Gas Filter Correlation technology PULSAR only measures the gas of interest, with negligible interference from other gases and water vapour. The optical bench is enclosed in a heated case so an external chiller is not necessary for non-condensing samples. By using two sample cells of different lengths in series, it is possible to select a low-range and a high-range, which increases the overall dynamic range. A parallel twin optical bench version is also available for applications requiring the measurement of two different gases or two ranges of the same gas running continuously.
