Honeywell Midas Gas Detector
BW Technologies by Honeywell

The Midas Gas Detector uses reliable sensor technology to detect many key toxic, ambient and flammable gases in a plant. The device monitors points up to 100 feet (30 meters) away while using patented technology to regulate flow rates and ensure error-free gas detection. Thanks to Honeywell’s use of advanced robotics, the Midas Gas Detector offers unbeatable quality and reliability:

Improved visibility and ease of use. The Midas Gas Detector is equipped with bright LED lights and an intuitive, interactive interface that provides instant alerts to gas readings or alarm levels. The interface also includes password-protected menus for configuration, test and calibration.

Easy installation. Compact in size with an easy-to-handle metal chassis, the Midas Gas Detector is simple to install. That’s especially important in crowded, complex process environments where space is at a premium.

Numerous applications. With feature-rich capabilities that are easy to use, the Midas Gas Detector is suitable for many industry applications, including semiconductor processing, light industrial manufacturing, university laboratories, aerospace, wastewater and more.

  • Detects more than 35 gases error-free

  • Improved visibility and ease of use
