Product Description

Fast, simple, and accurate differential pressure measurement is what the little measuring device testo 512-1, which measures pressures up to 200 hPa, is all about. It impresses in actual use thanks to its adaptability and range of uses. It is just as quick and accurate to inspect filters and measure with a Pitot tube in the ventilation duct as it is to check the gas pressure on burners by measuring gas flow pressure and static gas pressure. Measurement findings are trustworthy and extremely accurate thanks to the position-independent differential pressure sensor.

You are supported by the following features of the testo Smart App for tablets and smartphones:

  • Configure measuring instrument
  • Display graphical measured value curve
  • Save measurement data
  • Manage customers and measuring sites
  • Documentation on site
  • E-mail dispatch of the report

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.
