A lightweight and compact binary gas analyzer for measuring gas mixtures – such as air in argon or carbon dioxide in air. Suitable for installation in safe areas the XTC501 has a tough, IP55-rated housing. Available with an optional display and 4-button interface, the analyzer is easy to install, configure and operate.
How?
The thermal conductivity sensor has no consumable parts and will last the lifetime of the analyzer, XTC501 has a competitively low lifetime cost of ownership and is simple to maintain.
