The RP-2009 is a compact, battery operated, motorized sample drawing pump which attaches to the GX-2009 to change it from diffusion operation to sample drawing operation. Together, the model RP-2009 pump assembly and the GX-2009 gas monitor make a complete solution for confined space entry.  All pumps include a 4” rubber nipple for sampling and attach onto the GX-2009. The probe is equipped with an internal dust filter and clear body for easy viewing.
