Radio telescopes. Pulsars radiate most strongly in the radio spectrum so that is the best frequency range to observe them.

This instrument is a balance.
An instrument that measures heat and cold is called a thermometer.
A calorimeter measures heat. In contrast, a thermometer measures temperature.A thermometer bolometer - an instrument that measures heat radiation; extremely sensitive calorimeter - a measuring instrument that determines quantities of heatHeat is measured with a ThermometerThermometerThermometer or calorimeterThermometerthermometerHeat is measured with a thermometer.
An anemometer is the instrument that measures wind direction using a wind vane.
The instrument you’re referring to is a psychrometer. It consists of two thermometers: one measures the air temperature (dry bulb), while the other has a wet wick and measures the temperature of evaporation (wet bulb). This setup allows for the determination of relative humidity and moisture content in the air by comparing the two temperature readings.
A thermometer is used to measure the temperature of air, indicating whether it is hot or cold. Temperature readings are typically displayed in degrees Celsius or Fahrenheit.
A thermometer measures molecular energy.
