Kimo/Sauermann Si-RV4 wireless vacuum probe

The Kimo/Sauermann Si-RV4 is an advanced wireless vacuum probe that accurately measures absolute pressure to ensure optimal evacuation of refrigerant systems – down to deep vacuum – during service and commissioning of air conditioning, refrigeration, and heat pump installations.

With a wide measuring range from 50 to 25,000 microns and high measurement accuracy, the Si-RV4 enables fast and safe servicing of all types of refrigerant-based installations. The probe connects automatically and wirelessly to the Si-RM350 and Si-RM450 manifolds as well as to the Sauermann Pilot mobile app, where readings are displayed in real time.

The Si-RV4 is compatible with refrigerants in classes A1, A2L, A2 and A3. The probe must not be used with ammonia (NH3 / R717). With its IP54 protection, the unit is dust- and rainproof, making it well-suited for demanding outdoor use.
