Si-RV4

This wireless vacuum probe accurately measures absolute pressure, to ensure optimal refrigerant system evacuation down to deep vacuum in air conditioning, refrigeration and heat pump installations.

The Si-RV4 allows all types of refrigerant-based installations to be serviced quickly and safely. It connects easily to the Si-RM350 and Si-RM450 manifolds and to the mobile application Sauermann Pilot.
