The mercury analyzer PA-2 is used for continuous monitoring of mercury concentrations in industrial processes.
The PA-2 was specially designed for process analysis and operation under harsh industrial condition. The system comes with either the VM-3000 or the UT-3000 photometer to meet different requirements regarding accuracy and sensitivity of measurements.
