The RH1 Thermohygrometer is a highly accurate portable handheld measuring instrument for measuring relative air humidity, absolute air humidity, dew point, equilibrium moisture content of wood using innovative sensor technology.  The measuring range of the RH1 thermo- hygrometer is between 0 and 100% RH 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 the accuracy of +/- 1.5% of relative humidity (at 25°C) is reached.  The temperature measurement range is from -10 to +60°C or 14 to 140°F, at a resolution of 0.1°C. The accuracy is +/- 0.4°C.
