Si-RV4 Wireless vacuum probe

For Si-RM350 and Si-RM450 manifolds

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.

A1 / A2L / A2 / A3 refrigerants compatible
Compatible with some B1 refrigerants, see list of refrigerants for details on which refrigerants are compatible. The device must not be used with ammoniac refrigerant (NH₃ / R717).
