Infrared

Signal’s Infrared analysers offer superior performance in a wide variety of applications for the monitoring of all absorbing gases.

The principle that gases and liquids absorb light is something that we are all aware of without probably ever thinking much about it. Looking at the absorbtion of characteristic wavelengths of light to determine the concentration is the most widely used analytic technique for gases.

There are various designs of IR detector from very simple to very complicated, the most popular including dual beam and gas filter correlation both of which types refer to techniques used to reduce cross interference.

S4 PULSAR

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.
