Light-weight hands-free carry and handling at site

The EMP-3 is compact, lightweight and highly reliable portable continuous mercury analyzer. A portable atomic absorption spectrophotometer is installed in the equipment main body, so the equipment

is easy to carry to any site, where you can ensure simple and quick measurement of elemental vapor phase mercury in the working environment. The EMP-3 provides a variety of applications that suggest new mercury measurement methods that can change conventional practice.

Evolutionary, highly-sensitive instrument with compact and light body

The sample gas is directly taken into the absorption cell, and mercury concentration is measured by atomic absorption spectroscopy at absorbance of 253.7nm wavelength.

Both weight and size are reduced furthermore compared to our previous model.

The measurement range is as wide as 0 to 2,000µg/Nm3, and the response time is only 1 second. Measurement data is saved in CSV format in the SD card, which can be easily analyzed.Operation is performed on a touch panel type 4.3 inch color LCD.
