QAL 1 certified for continuous, accurate and reliable measurement of total mercury emissions, even in very low concentrations and within complex matrices (SO2, NOx, HCl, etc.)

With over 20 years experience, Mercury Instruments (part of ENVEA Group) were the first to develop mercury monitors and mercury analyzers using a dry thermocatalytic method instead of wet chemistry.

The SM-4 Mercury Monitor is QAL1 certified and is ready to meet future regulatory requirements (Minamata convention & European directives for thermal power plants and incinerators).
