PEAKMETER Digital Temperature and Humidity Meter LCD Thermo-Hygrometer Mini Thermometer Hygrometer Psychrometer Wet Bulb Dew Point Temperature Detector with Max/Min/Data Hold Mode

This is a portable meter for measuring relative humidity and temperature. It can display three types of temperatures around the sensor's air via several convenient procedures: the ambient temperature, the dew-point temperature and the wet bulb temperature.  

Features:
This digital thermometer hygrometer is a new type of digital temperature and humidity meter, which designed to combine the functions of humidity meter, temperature meter, wet bulb temperature and dew point temperature. And Dew point is a measure of how much water vapor actually in the air.
Dual display humidity and temperature with accurate measuring, easy to watch.
Digital humidity and temperature meter used for a high range of applications: HVAC, industry, agriculture, meteorology, medical, daily life, building engineer, paranormal investigator, in wine cellar, machine room and data storeroom.
Multiple Function: with data retention, data storage, unit conversion, backlight, low battery indicator, automatic shutdown, maximum and minimum functions.
LCD display with backlight with high accuracy sensor, LCD brighter in the darker places, auto power off, energy saving.
