The AMI rapidly detects and measures mercury vapours continuously, 24/7. AMI utilises a high stability control system and automatically self zeros every 5 hours, eliminating any potential drift. Simple to maintain, the instrument requires annual recalibration with filter replacement only - a sensor module exchange service makes the process quick and easy. AMI is the ideal survey unit for rapid, accurate levels of mercuy vapour detection. Robust portable and fixed options are available.
