RH1 Thermohygrometer

£30.00£520.00

The RH1 Thermohygrometer is an easy-to-use device for the rapid determination of the relative and absolute air humidity as the dew point temperature of the surrounding air.
In addition, the RH1 can be used to measure the equilibrium moisture content (EMC) and the water content in wood and paper. The RH1 will also display the current temperature –  in °C or °F – is displayed with each measurement.

The RH1 Thermohygrometer is an easy-to-use device for the rapid determination of the relative and absolute air humidity as the dew point temperature of the surrounding air.
In addition, the RH1 can be used to measure the equilibrium moisture content (EMC) and the water content in wood and paper. The RH1 will also display the current temperature –  in °C or °F – is displayed with each measurement.

The measuring range of the RH1 thermohygrometer is between 0 and 100% relative humidity at a resolution of 0.1%. The calibrated measurement range, in which the measurement is within the defined tolerance limits, ranges from 10% to 90% of the relative humidity, where an accuracy of ±1.5% of relative humidity (at 25 ° C) is achieved.

The temperature measurement range is from -10 to +60°C or 14 to 140°F, at a resolution of 0.1°C. The overall temperature accuracy is ± 0.4°C.

It possible to save the measurement readings manually or to save them automatically at defined intervals. The device can record up to 10,000 readings, which can be provided with additional information such as the location of measurement, batch number or supplier data.

Upon request, the device is also available with a USB data interface for connecting the RH1 to a PC. Using this interface, with the supplied USB cable and included PC software “LogMemorizer”, you can transfer your stored data values to the PC, where you can edit, analyze and store the data.

If you opt for the RH1 with the USB data interface, you can print stored measurements directly from the device on the available separate printer without needing to transfer the data to your PC.
