The Extech RH520B humidity and temperature chart recorder provides simultaneous numerical and graphical display of relative humidity, temperature and dew point readings, and shows date and time and min/max values. The detachable, replaceable probe extends up to one meter for measurements in closed environments and does not require recalibration.

The RH520B features programmable audible and visual high and low alarm limits for humidity and temperature. The RH520B's large LCD displays dual graphs with adjustable vertical and horizontal TAC resolution and allows scrolling to display the selected data recorded. The LCD also shows the percentage of memory remaining and a 5-segment battery life indicator.

The datalogger's internal memory records up to 49,000 data points and can be transferred to a PC for further data analysis. Free software is available for graphing of relative humidity, temperature, dew point, wet bulb, and GPP (grains per pound) or g/kg. The RH520B can be desk- or wall-mounted.
