RKI SP-220 Gas Leak Checker

The RKI SP-220 is a rugged, lightweight sample-draw leak checker built to pinpoint hard-to-find gas leaks at low concentrations. An integral pump pulls the sample through the probe so the operator can reach into tight spaces, and fast response with one-handed operation makes tracing a leak to its source straightforward. Features include a backlit LCD, moulded rubber cover, built-in LED work light, IP-55 weather protection, snap logging of 128 readings and data logging of 256 points. The type SC version uses a hot-wire semiconductor (MOS) sensor covering PH3, CH4, H2, HCl, ETO, HBr and NH3; the type FUM version uses the same sensor configured for fumigation gases including methyl bromide, sulfuryl fluoride and phosphine; type M is set up for methane and type L for LPG. Applications include gas distribution and service line leak surveys, pinpointing and post-repair verification, fumigation monitoring, refrigeration and process piping leak checks, landfill and soil gas screening, and tracing low concentration toxic or combustible leaks where a diffusion instrument is neither sensitive nor directional enough. Replacement MOS sensors and filters, probes and probe extensions, calibration gas cylinders and regulators, calibration kits, batteries and carrying cases are all stocked.
