Product Description
The RA-915M mercury analyzer is part of the analytical mercury complex, which has the unique ability to perform fast selective measurements of mercury concentrations in atmospheric air, gas streams, and liquid and solid samples. The original optoelectronic circuit of the analyzer provides an ultra-low detection limit (units of nanograms per cubic meter) of mercury in direct measurement mode (without preliminary concentration), high analysis selectivity and a wide dynamic measurement range (more than three orders of magnitude).
