About This Product

■Features

Dräger PointGard3720 is a complete one-channel gas detection system for measuring carbon dioxide in the atmosphere. All the necessary alarm equipment is included in a rugged yet compact housing with protection class IP66.

■All in one

The PointGard3720 is the perfect solution for those who need a gas detection system but don't have the hassle of assembling the necessary components. The device includes a transmitter with measurement functions, a controller with evaluation functions, and essential alarm devices such as flashing lights and buzzers. The AC version of the PointGard3720 operates by plugging the optional mains power into a standard power outlet. For optimal installation, mount the PointGard3720 and sensor far apart from each other. This allows the PointGard3720, alarm system, and display to be placed at eye level, while the sensor can be placed as close as possible to the measurement location. The maximum distance between PointGard3720 and sensor is 30m. The Dräger PIR7200 sensor included with PointGard3720 is ideal for use in hazardous areas. We also offer accessories suitable for use in piping and ventilation shafts.

■Application

If you need to measure gas concentrations locally, use the PointGard3720. A typical application is the measurement of carbon dioxide (CO2) in unventilated or closed rooms. In such locations, a PointGard3720 is installed outside the room near the entrance, and a sensor is installed inside the room to be monitored. In this way, it is possible to obtain information about the gas concentration before entering the room. When alarm limits are exceeded, PointGard's built-in alarm system issues a warning. Automatic ventilation can also be activated, allowing you to re-enter the room once the concentration has dropped and there is no danger.
