Compact and lightweight, this easy-to-use branded Crowcon Gasman CO2 detector is specially designed for the seamless detection of carbon dioxide. This design is effortlessly contrasted by its shrugged craftsmanship, making it extremely durable and resistant to some of the most hazardous environments

This carbon dioxide detector is well suited to a variety of sectors, including oil and gas, chemical plants, steelworks and even hospitality. Additionally, it offers high impact resistance, with added protection against dust and water.

Included is a large LCD backlit user display that makes it easy to read the gas concentration levels and battery life, in addition to visual, audible and vibrating alarms (vivid red/ blue visual warning are displayed).
