RA-915M Portable Zeeman Mercury Analyser

A Portable Multifunctional Atomic Absorption Spectrometer with Zeeman Background Correction. 

An advanced mercury analyser, the RA-915M is intended for the measuring of mercury vapour concentration in ambient air, residential quarters production areas and natural gas streams. 
RA-915M Mercury Analyser is a portable multifunctional atomic absorption spectrometer with Zeeman Background Correction, which eliminates the effect of potential interferences. It is the only highly sensitive mercury analyser that does not require gold amalgam pre-concentration and subsequent regeneration. This enables the user to conduct real time, second-by-second monitoring of vapour phase mercury.
