The thermo-hygrometer's reading of the humidity in the concrete slab will tell you how much excess moisture is present deep in the slab that might evaporate up through the surface. This can tell you if the concrete is likely to damage the materials above it or suffer other problems.

It is important to measure and record the temperature inside the concrete during the curing process. For this purpose, we have to insert thermocouples into the concrete and take the measurements using different types of instruments. This article gives a brief of different methods for measuring the temperature inside concrete at various points.

Jul 05, 2016 · This is an involved, time-consuming process, but it’s the best way to check the moisture conditions deep in the slab. When you need reliable information about the humidity conditions deep in a concrete slab so you can guarantee your work, use a thermo-hygrometer from a trusted manufacturer that knows the demands of the ASTM standard for concrete.

Just like our skin is sensitive to air that’s too dry or wet, plants need a careful balance of humidity for optimal health. Air that’s too arid can dry out plants. Air that’s too humid can lead to mold and plant fungus. The optimal relative humidity for a greenhouse will vary with the seasons. A hygrometer can help track the humidity.

A hygrometer is an instrument used to measure the amount of water vapor in air, in soil, or in confined spaces. Humidity measurement instruments usually rely on measurements of some other quantities such as temperature, pressure, mass, a mechanical or electrical change in a substance as moisture is absorbed. By calibration and calculation

Dec 02, 2018 · To fully understand how to use a hygrometer, it helps to know when and where you can use it.A hygrometer is an essential instrument in meteorological science. It has numerous commercial uses, but the primary purpose of the device is to measure the amount of water vapor (humidity) in the air.

Mar 09, 2017 · In simple terms, a hygrometer is a device that uses a range of different variables to measure the humidity of the air, the first rough hygrometer being invented by Leonardo da Vinci in 1480. For example, some hygrometers use the current temperature and an electric current monitor to accurately calculate the current humidity.
