This gas detector finds volatile substances at very low volumes

| By Mary Page Bailey and Gerald Ondrey

The new X-pid gas detector (photo) quickly detects volatile organic substances, such as benzene, even at extremely low concentrations. To determine the concentration of certain hazardous substances, the device combines two measuring modes, optimally supporting strategies for measuring in hazardous areas or confined spaces. It builds upon its predecessor with the addition of a search measuring mode, which allows for continuous monitoring for photoionization-detection (PID) sensitive compounds prior to using the analysis mode for a more specific analysis. The sensor unit can be controlled via an explosion-protected smartphone by means of a mobile application. — Dräger, Inc., Houston
