    Testo 805i Bluetooth Infrared Surface Temperature Thermometer

    PLEASE NOTE: Not all infrared thermometers are suitable for accurately measuring body temperature or detecting fevers (such as those commonly associated with COVID-19 or Influenza).

    For applications such as these we recommend the 8836M Non-Contact Forehead Ir Thermometer or Extech IR200.

    If in doubt please contact our Sales Department at 0113 248 9966.


    The Testo 805i Bluetooth Infrared Surface Temperature Thermometer takes surface temperature measurements from -30 to +250℃ within an accuracy of ±1.5-2.5℃ (or ±1.5%) via its non-invasive infrared sensor. With this ample temperature range and high accuracy level, the Testo 805i is great for measuring surface temperature in walls and in components and fuses within air-conditioning systems. The emissivity level can be adjusted from 0.1 to 1.0 depending on the user’s needs.

    A multi-point laser circle shows the measurement point whilst the 10:1 distance-to-spot ratio allows the user to take surface temperature measurements from a safe distance. Another useful feature is the special menu on the Testo Smart Probes App which helps the user diagnose mould-friendly temperature conditions.  The lightweight design and 30-hour battery life make it practical for lengthy inspections over large sites whilst the 2/sec measurement rate gives handy, real-time results throughout system phases. These innovative features made the Testo 805i a winner at the AGSM Gas Safety Awards 2016.

    As part of the Testo Smart Probes range, the Testo 805i works with the free Testo Smart Probes App on Android and iOS to display surface temperature readings on smartphone and tablet screens and then analyse/collate results in an easy-to-use format including Excel and PDF files for further forwarding. Multiple instruments can connect via Bluetooth to a smartphone or tablet at any one time to give a comprehensive system picture on the tablet/smartphone's screen. As well as being a useful single instrument, the Testo 805i is also part of the Testo Smart Probes VAC Set and the Testo Smart Probes Heating Set.

    Testo Smart Probes App

    The Testo Smart Probes App can be downloaded for free from the App Store or Google Play and works with all instruments in the Testo Smart Probes range. The App displays real-time readings on screen for a whole range of variables. Up to six Smart Probes can work in tandem and information can be saved in Excel or as a .pdf report (including pictures). Advanced analysis is available and the Testo Smart Probes range represents a major advance in system inspection and evaluation.
