Extech RH300 Hygro-Thermometer Psychrometer

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.

product overview

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.

function Extech RH300 Hygro-Thermometer Psychrometer

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.
