The Model RA-5 is the next generation CVAAS Mercury Analyzer from NIC. It is simple yet powerful. With multiple configurations available, a full-color LCD touch panel, and upgradable to an automated CVAAS mercury analyzer, the RA-5 is extremely versatile and cost-effective. The NIC RA-5 is super compact. It takes up about as much bench space as an 8.5 x 11” sized sheet of paper. This is a reduction of over 50% from previous models. The RA-5 can be used as a stand-alone mercury analyzer for those with only a few samples or limited budget without sacrificing performance. It can also be configured with one of three available autosamplers at time of purchase or as an upgrade in the future.
