RH1 Paper/cardboard storage 0-100% humidity
Climatic humidity measuring instrument with data logger / very fast adjustment procedure / long-term stable humidity and temperature sensors / large selection of characteristic curves Measured value memory for 10,000 measured values / lifetime support
With the Humimeter RH1 Lager, we have developed a measuring device with innovative sensor technology that is ideal for quickly determining the relative and absolute humidity as well as the dew point temperature of the surrounding air. It is also suitable for determining the equilibrium humidity (Ugl.) or the water content of materials such as wood or paper.
The RH1 humidity meter is easy to use and simultaneously displays the current temperature in °C or °F for each measurement. The measuring range of the RH1 hygrometer is between 0% and 100% relative humidity, with a resolution of 0.1%. The calibrated measuring range extends from 10% to 90% relative humidity, with an accuracy of +/-1.5% relative humidity (at 25°C). Bearing
The Humimeter RH1 allows manual or automatic storage of the current measured values, whereby up to 10,000 measured values can be provided with additional information such as location of the measurement, batch number or supplier. Optionally, a USB interface and a data link cable can be supplied to read out, edit, archive, export and further process the values from the device with the associated software "LogMemorizer".
If you choose an RH1 with interface, you can also print out stored measurements directly from the instrument via a separately available printer without having to transfer the data to the PC first.
The Humimeter RH1 climate humidity meter with data logger is an outstanding solution for quickly measuring the relative and absolute humidity as well as the dew point temperature of the ambient air.
It is also suitable for determining the equilibrium moisture content (Ugl.) and the water content of materials such as wood or paper.
The RH1 humidity meter is easy to operate. The current temperature in °C or °F is displayed at the same time as each measurement. The measuring range extends from 0% to 100% relative humidity, with a resolution of 0.1%. The calibrated measuring range extends from 10% to 90% relative humidity, with an accuracy of +/-1.5% relative humidity (at 25°C). Bearing
The RH1 enables the manual or automatic storage of up to 10,000 measured values, which can be provided with additional information such as the measuring location, batch number or supplier. A USB interface and a data link cable are optionally available to read out, edit, archive, export and further process the data with the "LogMemorizer" software.
If you opt for the version with interface, you can print stored measurements directly from the device without having to transfer the data to the PC first. The RH1 is a reliable and versatile instrument for moisture measurement and data recording in various applications.
Application area
In addition, the RH1 offers optionally available accessories to perfectly adapt the device to your requirements.
