Introduction Extech HD500 Psychrometer with InfraRed Thermometer

Extech HD500 is a versatile instrument designed for measuring various environmental parameters, particularly focusing on humidity, temperature, and infrared (IR) temperature measurements. It’s commonly known as a “psychrometer” due to its ability to measure the relative humidity of the air, a key factor in understanding human comfort and various industrial processes. The addition of an infrared thermometer adds the capability to measure non-contact surface temperatures, expanding its functionality.

The HD500 allows you to measure relative humidity (RH) using a built-in humidity sensor. Relative humidity is the amount of water vapor present in the air compared to the maximum amount the air could hold at a particular temperature. This measurement is important in various applications, such as HVAC systems, agriculture, and industrial processes.

The instrument measures ambient air temperature using a built-in temperature sensor. This is crucial for understanding the thermal comfort of a given environment. Additionally, the IR thermometer feature enables non-contact surface temperature measurements, which can be useful for checking the temperature of objects that are difficult to access or are at a distance.

The psychrometer is capable of calculating the dew point temperature, which is the temperature at which air becomes saturated with moisture and condensation begins to form. This measurement is essential in situations where preventing condensation is important, such as in electronics or industrial processes.

The wet bulb temperature is the lowest temperature that can be reached by evaporating water into the air at constant pressure. It’s a key parameter in calculating various heat and humidity indices. The HD500 can calculate this value based on its measurements.
