The relative humidity and temperature of the air environment are measured using geothermometers, which are psychrometers or thermometers. This gadget has an electrical module, a temperature sensor, and a humidity sensor.
Compact meters are great for field applications, and the RH300 is one of them. Displays ambient temperature, dew point, and relative humidity (10% to 90% RH) all at once. Utilizes optional probe (TP890) to determine T1-T2 difference (air temperature minus external probe temperature) and T2 minus dew point. built-in sensor cap protection. Data Hold, Auto Power Off, and MAX/MIN reading are additional functions. with two AAA batteries included.
The evaporation and cooling evaporation theories underlie how the psychrometer hygrothermometer gadget operates. Water vapor is transmitted to the humidity sensor in this gadget by placing a moist towel on it. The temperature and humidity are then measured simultaneously by the temperature and humidity sensors, and the results are shown on the digital screen.
