RA-2 (mercury analyzer )
Water Level Meters The RA-2A mercury analyzer is designed to analyze aqueous samples. This rapid easy to use reducing vaporization mercury analyzer has ultra-high sensitivity with a resolution of 0.1ng. The RA-2A Hg analyzer uses non-dispersive double beam cold vapor atomic absorption. Results are obtained in 30 seconds when in "peak" mode and usually in 2 minutes (variable one to 15 min) when in integrating mode. The RA-2A Hg analyzer uses a long-life Hg lamp for excellent long term stability. The tiny 8" x 15.75" footprint conserves expensive bench space . Ease of Operation with Microprocessor Control - Peak Height mode and Integral mode - Switch between modes by simply pushing a button.
- Clear easy to read display panel
Reliable - Long MTBF (meantime between failures)- Including Scrubber and Dehumidifier (electronic cooling)
- Stable long life mercury lamp
