Rapidox 2100 OEM-SIL2 Gas analyzer

The Rapidox 2100 OEM-SIL2 is a high-performance zirconia oxygen (O2) analyser, designed to meet the SIL2 requirements of IEC 61508/61511 under high demand use for safety integrity, as part of a Safety Instrumented System (SIS). The analyser design uses two microprocessors that continuously monitor the state of operation, quality of readings and the integrity of the digital & analogue outputs and the alarm relays. The likelihood of a fault being undetected is reduced by several orders of magnitude compared with a non-SIL2 equivalent product.
