Comtec O2 / combustibles analyser

Comtec O2 / combustibles analyser

The explosion protected gas analyzer COMTEC reacts immediately to process changes and is ideal for safe and exact measurements of oxygen and COe in refineries or similar areas with explosion hazards (Gas Ex zones1 / 2). The COMTEC GasEx fast flue gas analyzers are ATEX (II 2G Ex d IIC T3/T6 Gb) certified by a German test institute whereby the certifications encompass all parts of the analyzer system. This certification builds trust in plant security. This is coupled with ENOTEC’s compelling product quality, which is continually able to withstand the challenge of aggresive process conditions.

COMTEC gas analyzer for measurement of oxygen and COe (the sum of unburned molecules such as carbon monoxide, methane or hydrogen). Apart from the MXP sensor for determining the content of COe, a MLT sensor which is used in all OXITEC 5000 oxygen analyzer systems is also built into the Comtec. Because of its design, the COMTEC is practically maintenance free, with reliable and highly accurate measurements. To ensure high this level of reliability, the electronics have auto control functions, ensuring minimal maintenance during operation. The analyzer was specially designed as a 19″ rack system for use in industrial analyzer systems as are used the world over and can be used in combination with existing measuring equipment. Also available is a standalone desktop version which can be used for instance in laboratories.
