The Testo 115i pipe clamp thermometer is a Bluetooth-enabled wireless probe designed for measuring pipe temperatures in heating and cooling systems. Its spring-loaded clamp securely grips pipes up to 1.5 inches in diameter, maintaining critical contact between the probe and pipe surface for optimal readings. This ensures accurate temperature measurement essential for system diagnostics.

Users can read measurements using the Testo Smart Probes App installed on Android (4.3 or newer) or Apple (iOS 8.3 or newer) smart devices from up to 60 feet away. The app can connect up to six Testo smart probes simultaneously, displaying data as instrument readings, tables, or graphs. When used in conjunction with the Testo 549i refrigeration pressure probe, the system automatically calculates superheat and sub-cooling, simplifying HVAC/R troubleshooting.

The Testo Smart Probes App is a powerful, easy-to-use tool that allows remote reading, documentation, and reporting of measurements. Results can be quickly saved as PDF or Excel files, and custom reports can be shared via email. The 115i's rugged design and 2-year warranty ensure long-term reliability in field applications.
