The RKI SP-220 is a precision leak detector for combustible, toxic, freon and fumigation gases. The SP-220's rugged, light weight design and fast response time plus ease of operation will make pinpointing hard-to-find, low concentration gas leaks a simple procedure.

The SP-220 is available in four models. The M model is designed to find methane leaks. The L model finds LPG leaks. The SC model uses a hot-wire semiconductor sensor (MOS) that can detect a range of target gases including PH3, CH4, H2, HCL, ETO, HBr and NH3. The FUM model also uses the same MOS sensor and can detect fumigation gases including methyl bromide, sulfuryl fluoride and phosphine.

An integral pump, LCD display with backlight, molded rubber cover, LED light and weather protection (IP-55 rating) are some of the unique features of the SP-220. Snap logging (128 readings) and data-logging (256 data points) features allow for accurate record keeping and testing accountability. The SP-220 also has the ability to zero out background gas to help identify if you are getting closer to a leak source.
