Sauermann Si-RT7 Wireless Temperature Clamp

The Sauermann Si-RT7 Wireless Temperature Clamp is designed for HVACR professionals who need reliable and accurate temperature measurements for calculations of superheat and subcooling values in air conditioning, refrigeration and heat pump installations. Featuring an innovative “parrot-shaped” clamp, the Si-RT7 provides a secure grip along with perfect contact on pipes ranging from 6 to 42 mm (0.2’’ to 1.7’’) in diameter, delivering consistent measurement accuracy in all types of refrigerant-based installations.

The Si-RT7 is equipped with a fast-response NTC sensor that delivers accurate and stable readings in real time. It integrates seamlessly with the Sauermann's Si-RM350 and Si-RM450 digital manifolds as well as the Sauermann's Pilot App (available on iOS and Android), automatically connecting at a distance of up to 100 m (328 ft). This allows technicians to be flexible and work efficiently on-site with manifold systems or monitor data remotely on a smartphone.

It also features an IP54-rated protection against dust and rain, making it suitable for demanding field conditions. The Si-RT7 offers a measurement range from -20 to 85°C (-4 to 185°F) and is powered by three LR03 AAA 1.5 V alkaline batteries, giving it a healthy battery life of 150 hours at 20°C (68°F).
