The Si-RT7 is a wireless temperature probe designed for precise measurement of superheat and subcooling in refrigeration, air conditioning, and heat pump systems. With its wide measuring range from -20 to 85 °C and a sensitive NTC sensor, it delivers fast and accurate results, making commissioning and servicing both simple and reliable.

The parrot-shaped clamp ensures perfect contact on pipes with diameters from 6 to 42 mm, guaranteeing stable and precise measurements. The Si-RT7 connects automatically and wirelessly to the Si-RM350 and Si-RM450 manifolds as well as to the Sauermann Pilot mobile app, where data is displayed in real time.

Features and benefits

• Wireless temperature clamp for pipes from 6 to 42 mm
• Measuring range: -20 to 85 °C
• Precise NTC sensor for fast response and accurate measurements
• Enables calculation of superheat and subcooling
• IP54 dust- and rainproof design for outdoor use
• Automatic wireless connection to Si-RM350/450 manifolds and Sauermann Pilot mobile app
• Supplied with 3xAAA batteries, cardboard packaging

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.

Features and benefits

• Wireless vacuum probe with measuring range from 50 to 25,000 microns
• Measures absolute pressure for optimal and safe system evacuation
• Compatible with A1 / A2L / A2 / A3 refrigerants
• IP54 dust- and rainproof construction – robust for outdoor use
• Automatic wireless connection to Si-RM350/450 manifolds and Sauermann “Pilot” mobile app

Kimo/Sauermann Si-RS1 Smart Refrigerant Scale is a robust and precise digital refrigerant scale with a wired remote control and a large, easy-to-read display. It is designed for professional HVAC technicians who require accurate measurements and reliable performance in daily use.

With a measuring capacity of up to 110 kg, the scale can be used with all common refrigerants. Through wireless connection, the Si-RS1 integrates directly with the Si-RM350/450 smart manifold and Kimo/Sauermann’s Pilot mobile app, providing maximum flexibility and efficiency on the job.

The strong aluminum base and non-slip platform ensure stability even under demanding conditions, and the scale is supplied in a hard plastic case for optimal protection and easy transport.

Features and Benefits

• Digital refrigerant scale with wired remote control and large display
• Measuring range up to 110 kg
• Wireless connection to Si-RM350/450 manifold and Kimo/Sauermann mobile app
• Robust construction with strong aluminum base and non-slip platform
• Supplied in a hard plastic case for safe storage and transport

Kimo Sauermann has launched a new generation of digital manifolds – Si-RM350 and Si-RM450 – designed for precise and efficient handling of refrigerant installations such as heat pumps, air conditioning and industrial systems. With a robust design, IP54 protection and a clear anti-reflective display, they ensure reliable operation even under demanding conditions. The manifolds support all refrigerant types, including flammable ones, and combine advanced measurement technology with long battery life and integrated data logging (600,000 points).

Through the Sauermann Pilot app, users can easily control, log and share measurement reports, making the series a modern and future-proof tool for HVACR technicians.

The unit also connects wirelessly to the Sauermann Pilot app, the Si-RS1 refrigerant scale and wireless probes.

The kit includes:

• 1x Si-RM450 4-way manifold (4 ports), measuring range: -1 to 60 bar (-14 to 870 psi)
• 2x Si-RT7 wireless temperature clamps for pipes Ø 6–42 mm with NTC sensor, measuring range: -20 to 85 °C (-4 to 185 °F)
• 1x set of 3 refrigerant charging hoses, 1/4'' SAE, length 1 m (39”)
• 1x vacuum hose 3/8'' SAE, length 1.5 m (59”)
• Batteries (4xAA)
• Calibration certificate
• Durable hard plastic case
