Product Description

  • A robust metal folding joint, a rubber-coated anti-slip surface, a long and precise temperature sensor – and waterproof into the bargain! The testo 104 waterproof food thermometer comes with a whole host of practical features and benefits for use in the food industry.
    The food probe thermometer for the food industry
    Temperature checks play a vital role in quality assurance, cold chain documentation and hygiene regulations. The testo 104 waterproof food thermometer allows you to carry out quick and easy spot checks during the production, storage and processing of food. The food probe thermometer measures the core temperature of liquid, semi-solid and viscous media.
    The sleek thermometer with rugged sensor tip leaves virtually no trace when inserted. The thermometer can also measure the core temperature of food when the probe has been folded out at an angle of only 30°. This allows you to carry out reliable checks in difficult-to-reach places.
    The testo 104 is the only folding waterproof food thermometer which can be cleaned under running water after carrying out meassurements. The probe’s rugged metal joint allows it to be folded away and kept in its protective case until you need it again.
    And here’s another practical feature: the testo 104 waterproof food thermometer comes with a set of adhesive color strips which you can attachto the individual meters when more than one of the same model are being used.
    The testo 104 food probe thermometer is not only HACCP compliant and EN 13485 certified but also splash water protected making it ideal for use in the food sector.

Estimating wood’s moisture content: 

The amount of moisture in stored timber products will determine how they are used and processed going forward. When wood is installed with the incorrect moisture content, mechanical deformations (contracting and swelling) can occur at the location where the material is later employed, which can lead to damage to individual furniture pieces or entire supporting systems in buildings. Therefore, the appropriateness of the wood must be evaluated by measuring the moisture content before being manufactured into furniture or used as a supporting material by a craftsman.
A routine task for chimney sweeps and flue gas inspectors is to check the moisture content of fuels, such as firewood. A fuel with a high moisture content wastes resources and loses energy. All Testo wood and construction moisture measuring equipment calculates the amount of moisture in the material as a percentage of the dry mass (dry weight).
Other options for measuring resistance include using the material’s electrical conductivity or the magnetic flux leakage method, which gauges resistance using the electrical field within the material.
The testo 606-1 is a portable, highly useful tool for testing the moisture content of materials. Through the use of stored material characteristic curves for wood, the material moisture is directly presented in percentage weight. For assessing wood moisture in beech, fir, larch, oak, pine, and maple wood, characteristic curves are available. Five additional features are saved in the instrument. Two electrodes that have been driven into the material are used by the measuring device to take readings. The testo 606-2 detects ambient temperature and humidity in addition to material wetness. In this approach, it is possible to swiftly and accurately evaluate the conditions of drying on the spot.
