Gas dilution calibrator PermaCal

portablewith permeation oven

Multipoint dilution and permeation system developed in collaboration with the METAS (Swiss Federal Institute of Metrology). The most complex configuration consists in a double stage dilution and permeation system. The device can be available in a portable or rackable casing. PermaCal is able to generate precise and high-purity gas mixtures for the calibration and linearisation of analyzers, monitors or sensors. Designed mainly to calibrate and verify the linearisation of air pollution monitors such as SO2, NO2, NH3, it is very useful for air pollution monitoring (APM) application. This instrument generates gases that are not available or stable in gas cylinders (see wide list of gases).
