28142 Si-RT7 wireless temperature clamp by Sauermann
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.
Features
- High accuracy Pirani® sensor, 50 microns deep vacuum
- A1, A2L and A3 refrigerants compatible
- Quick & Strong wireless auto connection (100 m range)
- Real time readings on manifold and mobile app
- IP54 dust & rain proof probe
