Applications

The Testo 104 can be used for temperature checks throughout the food supply chain, including:

• Food manufacturing and processing

• Restaurants and commercial kitchens

• Catering operations

• Bakeries and confectionery

• Meat and poultry processing

• Dairy and milk products

• Frozen and chilled foods

• Food storage facilities

Folding Probe Design

The folding probe is one of the key advantages of the Testo 104. The probe can be folded into the instrument for convenient transportation and protection.

The thermometer can also measure temperature with the probe opened at an angle of approximately 30°, making it easier to access difficult-to-reach measurement points.

Waterproof IP65 Construction

The Testo 104 has an IP65 protection rating and can be cleaned under running water after use. This is particularly useful in food-processing and kitchen environments where hygiene is essential.

Note: IP65 protection does not mean the thermometer should be submerged in water. It is designed for protection against water jets and cleaning under running water.

Thin Precision Probe

The stainless-steel penetration probe has a 3 mm shaft diameter and a 2.3 mm tip diameter. Its slim design allows temperature measurements with minimal disturbance to the food product.

The 102 mm probe shaft provides sufficient reach for checking the internal temperature of many food products and materials.

Temperature Monitoring Functions

Auto Hold

Automatically recognizes the final stable temperature value and holds it on the display.

Hold

Allows the user to manually freeze the displayed measurement.

Min./Max. Memory

Stores minimum and maximum temperature values, helping users monitor temperature variations during inspections.

Food Safety & Compliance

The Testo 104 is designed specifically for professional food-temperature monitoring and is HACCP compliant and EN 13485 certified. This makes it suitable for temperature checks associated with food hygiene, quality assurance and cold-chain processes.
