MRV Series mobile cart continuous duty, constant flow, air sampling systems

This “Golf Cart” type unit can be used for the assay of both particulates and gaseous radioiodine. Its telescoping “Goose Neck” allows for industry-standard breathing zone air sampling.

There is a 3/8” female Quick Disconnect fitting at the sampling inlet which accepts all “RV” series filter holders.

Two vacuum gauges for measuring pressure differential across the filter media are conveniently mounted in a control box on the units handle along with a power toggle switch, fuse protection, and a resettable electronic elapsed timer. 

HI-Q's MCV-260 maintains a constant flow of ±5 of the operator pre-set flow rate (up to the maximum capacity of the pump).

The flow rate can be viewed by incorporating one of the HI-Q's optional "V-FLO-XX" venturi flow measurement units.
