Infrared gas analysers.
This NDIR unit provides continuous operation and can selectively measure and display the concentrations of up to four different gas components. The NDIR function principle is based on the absorption of infrared radiation by heteronuclear molecule gases with several atoms. Optimum sensitivity and high selectivity with regard to other components in the measurement gas are achieved by means of opto-pneumatic radiation receivers which are optimised for the application. Due to a built-in thermostat, even extremely small measuring ranges can be covered. An optional electro-chemical sensor makes it possible to additionally measure the oxygen concentration. Measuring range for oxygen up to 25 % by vol.

Type-tested according to German directives (TA-Luft and BlmSchV 13 and 17) For the following components:
0/250 mg CO
0/500 mg SO2
0/400 mg NO

A pressure-proof capsule version allows for use in Ex area, zones 1 and 2. The spectrum of measured components and combinations is growing constantly. An AFRISO expert will be pleased to answer any questions you have concerning your application. The conventional method with test gas can be used for calibration.
If the integrated calibration unit is used, test gas cylinders are not required. In addition, the system can be equipped with a pneumatic unit. It is also available in a housing for wall mounting.
