Continuous mercury monitor
in the working environment


Stationary continuous mercury analyzer of gaseous metal mercury in the working environment



Reliable data acquisition with a high sensitivity atomic absorption spectrometry

The EM-5 is stationary continuous mercury analyzer that measures elemental vapor phase mercury concentration in the working environment.

By adopting highly sensitive atomic absorption spectroscopy, a stable baseline and highly reliable data can be obtained. This equipment is operated at 100V.

The touch panel increased the operatability, which includes, in addition to measurement start/stop, the display of real-time mercury concentration of the measurement line, and settings of various conditions.


Variety of options suitable for various measurement condition

We have a variety of options to satisfy your measuring conditions.

In addition to the sample switching unit that has up to 8 lines, options such as the wet pretreatment equipment (WLE-5) that removes interference that affects mercury measurement, and data analysis software are available.
