Testo 915i Smart Probe Temperature Kit

The Testo 915i Smart Probe Temperature Kit gives you a solid setup for quick, accurate temperature checks on the job. It's built for HVAC/R techs who need to measure air, liquid, and surface temperatures fast, and then log results easily through their phone.

Out on a hot Aussie roof, you need reliable readings without fuss. This kit uses wireless probes and Bluetooth, so you can get into tight spots or keep an eye on temps from a distance, making those tricky coil or pipe measurements a lot smoother.

Best For

This kit is ideal for:

• HVAC/R technicians doing system commissioning and maintenance.
• Refrigeration mechanics checking evaporator and condenser temps.
• Service teams troubleshooting airflow or heating issues.
• Competent DIYers maintaining their own air conditioning systems.

Compatibility

The Testo 915i handle works with all standard Type K thermocouple probes, not just the ones in this kit. It connects automatically via Bluetooth to the free Testo Smart App on your smartphone or tablet (iOS 12.0+ or Android 6.0+ required with Bluetooth 4.0). It can also link up with other Testo measuring instruments like the Testo 400 or Testo 550s.

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

Features

• Wireless Smart Probe System: Measure temperatures without cable clutter, perfect for tight spaces or monitoring from a distance up to 100 metres via Bluetooth.
• Three Included Probes: Comes with an air probe, an immersion/penetration probe, and a surface probe, all robust TC Type K, Class 1 for various applications.
• Universal Type K Compatibility: The 915i handle accepts all standard Type K thermocouple probes, expanding your measurement options.
• Testo Smart App Integration: Easily view readings, visualise temperature curves, create on-site documentation, and send reports as PDF or CSV files directly from your smartphone.
• High Accuracy: Delivers reliable measurements with accuracy up to ±1.0 °C, ensured by ex-works system calibration.
• Secure Probe Locking: Features an innovative locking mechanism on the handle for quick, secure attachment and detachment of probes.

Using It on the Job

1. Power Up & Connect: Insert the supplied AAA batteries into the 915i handle. Turn on the unit, then open the Testo Smart App on your mobile device. The probe should connect automatically via Bluetooth within range.
2. Select & Attach Probe: Choose the appropriate probe for your measurement (air, immersion, or surface). Use the innovative locking mechanism on the handle to securely attach the probe.
3. Measure Temperature: Position the probe at the measurement point. For surface temps, ensure good contact. For immersion, fully submerge the tip. Read the live data on your smartphone or compatible Testo instrument.
4. Document & Report: Use the Testo Smart App to log readings, view graphical trends, add customer details, and generate reports. You can email these directly from the app as PDF or CSV files.
5. Clean & Store: After use, clean probes thoroughly, especially the immersion/penetration probe. Store all components in the supplied Testo Smart Case to protect them from damage and dust.

Limitations & Safety Notes

• Always operate within the specified temperature ranges for each probe to prevent damage and ensure accurate readings.
• Ensure the Testo Smart App is updated to the latest version for full functionality and compatibility with your mobile device.
• While versatile, this kit is specifically for temperature measurement; do not use it for pressure, vacuum, or electrical tests.
• Follow all site-specific safety procedures and use appropriate PPE when taking measurements, especially in industrial or potentially hazardous environments.

Tradie Pro Tip

Keep a spare set of AAA batteries in your kit bag, especially for long days on site. There's nothing worse than a dead battery when you're halfway through logging critical temperature data for a fault report.

Pair With

For a more comprehensive diagnostic setup, pair this Testo 915i kit with a set of Testo digital manifold gauges and a quality clamp meter from the HVAC Shop range. This gives you all the core data points you need for full system analysis.
