testo-915i-thermometer

The Testo 915i combines a Bluetooth thermometer handle with plug-in Type K probes for air, surface, immersion, or flexible-probe measurements. TruTech Tools carries the 0563 4915 flexible-probe version; other variants include dedicated probes or a three-probe kit.

Handle and Probe Measurement Ranges

The handle covers -76 to 1,832 °F (-60 to 1,000 °C) with accuracy of ±(0.9 °F / 0.5 °C + 0.3% of reading), ±1 digit. The measuring range and system accuracy depend on the attached probe. Flexible, air, and immersion/penetration probes cover -58 to 752 °F (-50 to 400 °C); the surface probe covers -58 to 662 °F (-50 to 350 °C). The specification table lists the probe-specific accuracy bands.

measureQuick Wireless Integration

The 915i connects directly to measureQuick over Bluetooth, sending temperature readings into the test record with no hand transcription. The datasheet specifies a wireless range of up to 328 ft (100 m).

Build and Field Readiness

The IP30 handle accepts the locking Testo probes and other common plug-in Type K probes. Three AAA batteries provide about 150 hours at 77 °F (25 °C) with a one-second measurement cycle. The flexible-probe version includes an 800 mm (2.6 ft) fiberglass cable; the temperature kit includes air, immersion/penetration, and surface probes with a carrying case.
