Review on 🌡️ Extech RHT510 Hygro Thermometer Psychrometer: Accurate Measurements for Humidity and Temperature by Sean Spence

Have you noticed that the day is nice when it's 50 degrees outside? If the thermometer in the house shows the same, it is cold there. Why is this? This is due to the different relative humidity. Weather dot gov actually has a special chart called "Heat Index" that compares temperature to relative humidity at a temperature that "feels like". This handy little device quickly determines temperature and relative humidity by pressing the "M" button. As you can see from the attached image, maintaining relative humidity here in Rochester, NY is not easy. While writing this review, I realized that my Honeywell Top Fill Cool Mist Humidifier, Black, has run out of water. In addition to temperature and relative humidity, this device can also measure dew point and wet-bulb thermometers (psychrometers) with the supplied probe.
