Relative Humidity (RH) Moisture Meters for Concrete
Set concrete cannot be easily penetrated by a pin meter, and it wouldn't allow for measuring in the core of the slab anyway. Therefore it’s often best to measure concrete with an thermo-hygrometer (RH meter). These devices comply with the global measurement ‘gold’ standard known as ASTM F-2170-11.

Moisture Testing: How to Care for Your Thermo-Hygrometer
Thermo-hygrometers, or relative humidity (RH) meters, are powerful instruments used on large construction materials like concrete to measure the presence of moisture.By measuring RH and temperature, thermo-hygrometers enable contractors and craftsmen to know when a material is ready.
How to Use a Hygrometer and How Does It Work? | ThermoPro
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.
What You REALLY Should Know About Concrete Moisture Meters
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.
What is a hygrometer and how to measure relative humidity ...
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.
A digital thermo-hygrometer is an electronic instrument that can measure and display the current temperature and relative humidity. It is small enough to be portable or hand-held, and it typically uses batteries for power. The components measure temperature and humidity with changes in electrical ...
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.
Jul 27, 2020 · The thermo-hygrometer will read the relative humidity and temperature in the air and based on those number, calculate a dew point temperature. With that temperature, you can go around to areas in your house that are showing signs of condensation and use the IR thermometer to measure surface temperature.

Digital Thermometer and Hygrometer | Konga Online Shopping
With the help of thermo-hygrometer devices, these conditions can easily be displayed and moreover controlled. If the air humidity is too high, you can for example open a window. If it is too low, an air humidifier can be used. Thermo-Hygrometers can be used to measure moisture content in various materials including wood, concrete, plaster and ...
Understanding Relative Humidity and the Hygrometer
Calibrating your hygrometer depends on your model. In some, a small screwdriver is used on the back panel's set screw to change the indicator reading. In other models, the entire hygrometer movement is rotated until the dial reads appropriately. Manufacturer's instructions for other configurations would apply. Testing hygrometer accuracy.
The 5 Best Hygrometers and Humidity Moisture Meters Reviewed ...
Thermal hygrometers measure the change in the thermal conductivity of the air due to humidity. This type of thermo hygrometer measures absolute humidity as opposed to relative humidity. Gravimetric hygrometers measure the mass of an air sample and compare it to the same volume of dry air.
A thermo-hygrometer measures humidity and temperature. A psychrometer has two thermometers (one wet and the other dry) that measures temperatures and can be used to calculate humidity. The property of the air is called the equilibrium moisture content (EMC) and it is numerically equal to the MC that wood will achieve during drying if you wait ...
In our continuing effort to respond to industry demands, Delmhorst is proud to introduce the HT-4000, a versatile thermo-hygrometer for flooring installers and restoration contractors alike. The HT-4000 s detachable RH sensor makes it ideal for ASTM F2170 concrete slab testing or for monitoring the relative humidity of the air in a structure.
Hygrometers are used to measure the amount of water vapor or humidity in the atmosphere, soil, or other spaces. Instruments that measure humidity typically also measure temperature, pressure, mass, or even a mechanical or electrical change in a substance that absorbs moisture because those factors can also affect humidity.
