Product Description
The testo 104-IR food safety thermometer is ideal for carrying out temperature and food safety checks. And because it fits snugly in any pocket, it’s always there when you need it to carry out checks on incoming goods, spot checks during transport or food inspections in the retail industry.

Probe thermometer and infrared thermometer rolled into one
The testo 104-IR is equipped with a high-precision 2-point laser and 10:1 optics which show the exact measurement range and allow you to carry out quick and accurate non-contact surface temperature measurements. The 2-in-1 thermometer is especially useful for checking incoming goods and for scanning the surface temperature of individual food products as well as whole pallets.

The folding probe thermometer is used to measure the core temperature of food products like meat and sausage meat for example. It generally comes into play when the infrared surface measurements are not within the prescribed thresholds. The probe can be folded away when not in use to protect against breakage.

Quick and easy to use. Tried and tested in the field
The thermometer is immediately activated when the probe sensor is folded down. Simply press a key to start the infrared measurement. The results are presented on a large, easy-to-read display. Because the keys themselves are easy to understand, there is no need to instruct individuals on how to use the thermometer. Last but by no means least, the food safety infrared thermometer is waterproof and IP65 rated.

Areas of Application
It doesn’t matter whether the food in question is being delivered, is in transit or in storage – in all three cases it is imperative that the cold chain is maintained at all times. The testo 104-IR food safety thermometer is ideal for ensuring that the prescribed temperature is maintained at each point in the cold chain. And like all the testo temperature meters for the food industry the testo 104-IR is EN 13485 certified and HACCP compliant.

Long, pointed thermocouple probe: ideal for measurements in liquids, soft or powdery substances and in the air

The testo 905-T1 penetration thermometer enables reliable temperature measurements in liquids, soft or powdery substances and in the air. In doing so, it is the temperature measuring instrument's large measuring range and its short response time that make it stand out. Both advantages are due to the high-quality type K thermocouple probe.

Product Description:
The testo 905-T1 penetration thermometer has a large measuring range from -50 to +350 °C and can even measure up to +500 °C for a short time (1 to 2 minutes). Its permanently integrated type K thermocouple probe makes this possible. In addition, the penetration thermometer is characterized by its short response time. The thermocouple probe reacts very quickly, particularly in water (or other liquids). The penetration thermometer is therefore ideally suited for measurements in fluid substances in laboratory, chemical and pharmaceutical areas.
However, as well as immersion/penetration of the long, pointed probe shaft in liquids and soft or powdery substances being possible, you can also insert it in ventilation ducts to measure the temperature there. The penetration thermometer is also a winner when it comes to accuracy, because it achieves a higher level than typical comparable models.

A really user-friendly penetration thermometer
The testo 905-T1 penetration thermometer is easy to use and very user-friendly. The measuring values are shown very legibly on the display. The fact that the display can be pivoted also makes reading easier. This is particularly practical, since the measuring values can be read off perfectly from many different perspectives.
