testo Sonda de temperatura -20 a +50 °C con conexión Bluetooth® al smartphone, sonda flexible (0563 4915)

Monitoring temperature in hard-to-reach or mobile environments often means being tied to a bulky handheld meter. This Bluetooth® temperature probe from Testo frees you from that constraint by streaming measurements directly to your smartphone or tablet. The flexible probe reaches into tight spaces, while the free Testo Smart App turns your mobile device into a live display and data logger.

Who is it for

HVAC technicians, food safety inspectors, laboratory staff, and field service engineers who need quick, accurate temperature checks without carrying a dedicated display unit. It is especially useful for spot checks in refrigeration, air conditioning, and process control where mobility and simplicity matter.

Tips

For the fastest response, immerse the probe tip at least 50 mm into the medium. The flexible shaft can be bent to reach awkward spots, but avoid kinking it sharply. Keep the instrument within Bluetooth range of your phone for reliable data transmission, and replace all three AAA batteries at the same time to maintain performance.
