Product Description

The testo 104-IR BT penetration infrared thermometer was developed for fast, reliable temperature checking in hectic day-to-day practice. In combination with the testo 250 HACCP management system, this measuring instrument ultimately enables paperless performance and documentation of temperature measurements. This means it simplifies and optimizes adherence to food safety standards and directives.

Always there when it is needed

There are a wide range of measuring tasks associated with adherence to HACCP directives. However, the testo 104-IR BT is equal to them all – no matter whether in incoming goods, storage or the counter display. It carries out non-contact surface temperature measurements with its infrared sensor. In order to achieve even more precise readings or to check for any violations of limit values, the hinged penetration probe also enables fast core temperature measurement. All readings are automatically sent via Bluetooth to the HACCP Check App on the testo 250 Tablet. This saves the data and supports employees on site, including when there are violations of limit values, using stored corrective measures.

The compact instrument's penetration probe is always securely stowed away on the instrument itself. As soon as it is opened up, the display automatically switches on. And IR measurement starts at the touch of a button. Thanks to the large illuminated display, it is really easy to read the measurement result.

There are just a few buttons which are self-explanatory and any user will find it really easy to operate them. No time-consuming measurements, no complicated handling, no compromises. You've got all temperature measurements in the food sector under control with the testo 104-IR BT.
