The NIC EM-5 is intended for continuous monitoring of any gaseous mercury present in work environments. The NIC EM-5 has sensitivity down to 0.001 mg/m3, complying with the safety limits of 0.015 mg/m3 set by the WHO. An external gas scrubber option can be coupled to remove interference. Each NIC EM-5 can be connected with a line switching module for 2 to 8 channels.
