Description
Part 72-0123RK is an NP-237H kit built around the 72-0122RK general use detector calibrated for isobutane. The RKI NP-237H is a portable combustible gas detector that reads from the lower explosive limit up to 100% by volume. A range change-over switch lets the user step between scales, and the instrument is suited to measuring hydrocarbon gas and vapor in an inert gas atmosphere, such as tank inerting. It is offered in land-use and marine versions. Tanker crews, terminal operators and gas-freeing contractors use it during inerting, purging and gas-free checks.
