S4 PULSAR - NDIR Multi-gas analyser

Non Dispersive Infrared (NDIR) Multi-gas analysers are available in 1, 2, 3, 4 or 5 gas channel configurations, offering high levels of performance and flexibility. Options include CO, CO2, CH4, NO, N2O, SO2, HCl and O2.

Product Description

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.

Technical Specification

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.

Applications

  • Boiler and Combustion Performance
  • Process Emission Monitoring
  • Automotive
  • Research and Test

Gases Sensed

  • Carbon Dioxide
  • Carbon Monoxide
  • Methane
  • Nitric Oxide
  • Nitrous Oxide
  • Sulphur Dioxide
  • Oxygen

Optional Configurations

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.
