The Testo 915i Flexible Thermometer is a wireless Smart Probe designed for fast and reliable temperature measurement in locations where standard rigid probes cannot reach. Equipped with a flexible, fast-response Type K temperature sensor with an 800 mm fibreglass-coated cable, it easily passes through drill holes, gaps, and door seals to capture accurate temperature readings from otherwise inaccessible areas. With a measurement range of –50 to +400 °C, it is ideal for HVAC, refrigeration, and industrial applications.
The instrument connects automatically via Bluetooth® to the Testo Smart App or compatible Testo measuring instruments such as the testo 400 or testo 550s. The Smart App allows intuitive operation, graphical temperature curve display, on-site documentation, and export of PDF or CSV reports. The innovative locking mechanism ensures secure attachment of plug-in probes, and the handle is fully compatible with all standard Type K thermocouple probes.
Durable, lightweight, and exceptionally versatile, the Testo 915i offers greater flexibility, speed, and convenience for professional temperature measurement in demanding environments.
