New multigas detector measures in low-ppb range

| By Gerald Ondrey

The focus of the X-act 7000, in combination with the MicroTubes for different gases and vapors, is to measure carcinogenic and toxic substances in the lower parts-per-billion (ppb) range. The range of gases to be measured is being constantly expanded. The measurement-sensitive system of the X-act 7000 is based on colorimetric chemical-sensor technology and measures even the lowest ppb concentrations. It can replace conventional laboratory analysis and delivers exact, reliable results directly on site. False-positive measurement results and false alarms can be largely reduced. This saves time and costs. The RFID tags applied to the MicroTubes contain all the calibration data that are valid for the typical period of use of one year. Complex functional tests and manual calibration procedures are no longer necessary. All possible temperature and humidity influences are already taken into account during factory calibration. The analyzer is explosion-proof and certified in accordance with ATEX/IECEx for zone 0 and CSA Class I, Zone 0. — Dräger Safety AG & Co. KGaA, Hamburg, Germany
