Si-RP4 Wireless pressure probe

For Si-RM350 and Si-RM450 manifolds

This wireless pressure probe provides accurate high and low-pressure measurements for air conditioning, refrigeration and heat pump installations.

The Si-RP4 allows all types of refrigerant-based installations to be serviced quickly and safely. It connects easily to the mobile application Sauermann Pilot via a low-power wireless communication protocol.

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).

Designation: Si-RP4 Sales reference: 28144

From -20 to 50°C (-4 to 122°F) This wireless probe provides accurate temperature measurement to enable the calculation of superheat and subcooling values in air conditioning, refrigeration and heat pump installations. Its parrot-shaped clamp ensures perfect contact with pipes from 6 to 42 mm. The Si-RT7 allows all types of refrigerant-based installations to be serviced quickly, thanks to the excellent responsiveness of its NTC sensor.
