The Testo 915i Smart Probe with surface probe is your go-to for quick, wireless temperature checks on the job, especially handy for those awkward uneven surfaces. It links straight to your smartphone or tablet via Bluetooth, making data logging and reporting simple, even when you're on a hot rooftop with a dozen other tasks on the go.

This kit features a fast-response Type K surface probe, perfect for pipes, plenums, or cabinet walls. It's built tough for Aussie conditions and works with the Testo Smart App for easy data management.

Best For

• HVAC/R service and maintenance technicians
• Refrigeration apprentices learning temperature diagnostics
• Anyone needing fast, accurate surface temperature readings on varied surfaces

Compatibility

The Testo 915i system is highly versatile. It's compatible with all standard Type K thermocouple probes, meaning you can swap out probes for air, immersion, or clamp applications as needed. The unit connects wirelessly to your smartphone or tablet (iOS 13.0+, Android 8.0+ with Bluetooth 4.2) and integrates with other Testo measuring instruments like the Testo 400 or Testo 550s.

If you're running a different model, check fittings and specs before ordering.

Features

• Fast-response Type K surface probe with a sprung thermocouple strip to adapt to uneven surfaces like pipes.
• Wide measuring range from -50 °C to +350 °C, suitable for most HVAC/R applications.
• Automatic Bluetooth connection to the Testo Smart App or compatible Testo instruments with up to 100 m range.
• Innovative locking mechanism for secure attachment of Testo plug-in probes.
• System calibration from the factory ensures high measurement accuracy up to ±1.0 °C.

Technical Specifications

What's in the Box

• Testo 915i Smart Probe Bluetooth handle
• Surface probe (TC Type K)
• 3 x AAA batteries
• Calibration protocol

Using It on the Job

1. Install the 3 x AAA batteries into the Testo 915i handle and attach the surface probe securely using the locking mechanism.
2. Download and open the free Testo Smart App on your compatible smartphone or tablet.
3. Power on the 915i; it will automatically connect via Bluetooth. Confirm connection in the app.
4. Ensure the surface you're measuring is clean and dry. Apply the sprung thermocouple strip firmly to the surface for optimal contact.
5. Read the temperature in the app, where you can also view graphical temperature curves, log data, and create reports for clients.
6. After use, power off the probe. Clean the probe tip if necessary and store the unit in a protective case to prevent damage.

Limitations & Safety Notes

• Rated for IP20 protection; avoid exposure to water or excessive dust.
• Always ensure the probe is clean and properly seated for accurate readings.
• Do not use on live electrical components without proper insulation and verification.
• Follow all Australian Safe Work practices when performing temperature measurements on HVAC/R systems.
• Only for the temperature ranges and applications specified in the technical data.

When you're trying to get a pipe temperature, don't just 'touch it on'. Use a bit of thermal paste or even a dab of Blu Tack to ensure solid contact with the sprung strip. It'll make a huge difference to your accuracy, especially on older, rougher pipework.

Pair With

For comprehensive system checks, pair the Testo 915i with other Testo Smart Probes like a Testo 550s digital manifold and a quality vacuum gauge. Don't forget a sturdy Testo Smart Case for keeping your gear organised on the ute.
