Vapor Analyzer – Model Q200

High Sensitivity Trace Gas Leak Detection

The D-Industrial Vapor Analyzer – Model Q200 is a portable instrument consisting of a carrying case that contains the power supply and electronics, a small cylinder of compressed argon gas, and the main display panel. The detector is mounted in a handheld probe, attached to the main unit by means of a 3.5 meter umbilical connection. A display panel is mounted in the hand probe to enable the operator to monitor measurements even when working in difficult locations.

The instrument is extremely easy to use, and provides highly accurate leak rate measurements. The response is almost instantaneous and the detector recovers quickly, even after exposure to high concentrations of trace gas. Where products are manufactured or maintained to a high leak tight specification the Q 200 is an invaluable aid in ensuring quality.
