Product Description

Developed for fast, reliable temperature checking in the hectic day-to-day food industry environment, the durable testo 104-IR BT is a waterproof (IP65) penetration thermometer combined with an infrared sensor for non-contact temperature measurement.

Used in conjunction with the testo Saveris quality management solution, this instrument helps food distributors improve the operational efficiency of food safety-related tasks and streamline data collection procedures by digitally recording temperature measurement values. Also recorded is a detailed account of when measurement was taken and by whom, in a centralized database.

Always there when it's needed

The testo 104-IR BT can be used to complete a variety of different tasks (such as incoming goods checks, storage temperature checks, hot/cold holding temperature checks, etc.) to help food distributors ensure they are meeting current regulatory monitoring standards.

The instrument’s infrared sensor carries out non-contact surface temperature measurements. For more precise readings, the hinged penetration probe provides fast internal temperature measurement. All readings can be easily sent via Bluetooth to the testo Saveris Tablet and Cloud. This saves the data and supports employees on site.
The instrument's penetration probe securely folds away when not in use. As soon as the probe is opened up, the display is activated, and the IR measurement starts at the touch of a button. Thanks to the large display, it is easy to read the measurement result.
Its few buttons are ergonomically placed and user friendly. No time-consuming measurements, no complicated handling, and no compromises. With the testo 104-IR BT, you can be sure all relevant quality procedures are under control.
