The Testo 115i pipe clamp thermometer measures the temperature of pipes in heating and cooling systems. It grips a pipe up to 1.5 inches in diameter while maintaining critical contact between probe and pipe surface to derive the best readings. You can used these in conjunction with the Testo 549i refrigeration pressure probe to calculate superheat and sub-cooling.

Users can read the measurements using the Testo Smart Probes App installed on their Android (4.3 or newer) or Apple (iOS 8.3 or newer) smart device from up to 60ft away.

The Testo Smart Probes App is a powerful and easy-to-use tool. It allows you to remotely read measurements from up to six Testo smart probes and easily document/report the results. All measurement data is displayed as instrument readings, tables, or graphs. The measurements can be quickly saved as PDF or Excel files. The App creates custom reports which can be saved and/or shared by email.
