This model has two versions and is a combination type portable HC/O2 or CH4/O2 gas detector with an Infrared (NDIR) type sensor and galvanic cell type sensor. These sensors provide accurate detection of HC/O2 (HC version) or CH4/O2 (CH4 version) levels even in N2 and other inert environments. The measuring ranges are 0-100%LEL/0-100 vol% for HC or CH4 and 0-25 vol% for )2 respectively with automatic ranging. The RX-415 has explosion proof and intrinsically safe construction so that it can be used safely in any environment.
