Total Mercury Analyser MERCEM300Z

MERCEM300Z – The sophisticated Way of Mercury Monitoring

The new MERCEM300Z was especially designed for the reliable monitoring of total mercury emissions in flue gases. Due to its patented direct measuring principle all effective as well as currently discussed regulatory requirements can be fulfilled. The unique integrated adjustment cell secures long term stable measurements by enabling automatic drift control and optical adjustment. Via the integrated calibration unit (option) daily automatic system and calibration checks (according to Part 75 are possible. The proven SICK system operation concepts as well as modern communication protocols turn the MERCEM300Z into an overall measuring solution: Easy to integrate, easy to operate and longterm reliable.
