Si-RM450 4-Way Digital Manifold | Sauermann HVAC/R Manifold Gauge

The Sauermann Si-RM450 is a high-performance 4-way digital manifold gauge designed for precise, rapid commissioning and servicing of all HVAC/R systems. Built for air conditioning, refrigeration, heat pumps, and industrial cooling applications, it combines advanced diagnostics, a smart digital assistant, wireless connectivity, and a rugged IP54 construction. Supporting A1, A2L, A2, A3, and selected B1 refrigerants (excluding NH₃/R717), the Si-RM450 ensures reliable, accurate, and versatile performance for both domestic and industrial use.

Features:

  • Compatible with A1, A2L, A2, A3 and selected B1 refrigerants (not for NH₃/R717).
  • 4-way manifold with 3× 1/4" MFL + 1× 3/8" MFL pressure connectors.
  • High-speed NTC temperature sensors for fast temperature measurement.
  • Durable anti-reflective display for clear visibility in any environment.
  • Rugged IP54 housing suitable for harsh jobsite conditions.
  • Wireless connectivity for data logging and mobile diagnostics.
  • Works with the Sauermann Pilot smart assistant app.
  • Wide pressure measuring range: –1 to 60 bar (–14 to 870 PSI).
  • Supports units: PSI, kPa, bar, MPa.
  • Long 300-hour battery life using 4× AA batteries, plus USB-C power option.
  • Ideal for AC, refrigeration, heat pumps, and industrial HVAC/R systems.
  • Large refrigerant database covering 100+ refrigerants.
