Testo 115i Wireless Pipe Clamp Thermometer — Superheat, Subcooling & Flow/Return Temperatures
The Testo 115i is a wireless pipe clamp thermometer from the Testo Smart Probes range, designed for measuring pipe temperatures in refrigeration and air conditioning systems. It connects to your smartphone or tablet via Bluetooth and the testo Smart Probes App, allowing you to monitor flow and return temperatures, calculate superheating and subcooling, and view graphical temperature change data — all from your mobile device.
The 115i is particularly useful when measuring temperatures at widely spaced points — the wireless connection means you don’t need to stand at the instrument to read the display. When used with the Testo 549i pressure measuring instrument, individual refrigeration system parameters can also be calculated in the app.
Confirm current testo Smart Probes App compatibility with your smartphone OS version before ordering. Confirm pipe diameter compatibility and all specifications against the Testo 115i datasheet for your specific application. Refrigerant system work requires appropriate trade qualifications — confirm licensing requirements in your state or territory.
