Climate meter PCE-EM 890

Climate weather measuring device for recording various environmental data / Various measuring functions / MAX / MIN measurement / High accuracy

The climate meter PCE-EM 890 is an instrument for measuring environmental conditions. The climate meter gives you an accurate measurement very quickly. Due to the small dimensions and the low weight, this climate meter is an easy-to-use information system on the weather condition. It is possible to switch between the measuring functions with just one push of a button. Thus, this climate meter is ideal for technicians, sailors, farmers and many other people who are dependent on the weather or whose activities are significantly influenced by the weather.

With just one gauge, you can read wind speed, temperature, wind chill (sensed temperature), dew point, relative humidity, heat index, barometric pressure, and height above sea level. The anemometer offers you the functions of the individual measured value, minimum value, maximum value measurement.

Explanation of various environmental conditions:

Wind Chill
The wind chill describes the difference between the measured air temperature and the sensed temperature as a function of the wind speed. Some of our anemometers can record the wind chill and other parameters.

Air Pressure
The air pressure at any location in the Earth's atmosphere is the hydrostatic pressure of the air that prevails in that location. This pressure is consistent with the weight of the column of air that is on the surface of the earth or a body on it. The average atmospheric pressure of the atmosphere at sea level is 101325 Pa = 1013.25 hPa = 101.325 kPa and is thus part of the normal conditions.

Dew Point / Dew Point Temperature
Air can absorb more water vapor with increasing temperature. With decreasing temperature of a building material or the air, in which the relative humidity of 100% is reached, then the excess water vapor precipitates in the form of condensation. The boundary area is called dew point. Buildings should be designed so that the dew point temperature on the inside of the air tightness layer is not undershot. The formation of condensation and resulting structural damage or mold is thereby avoided. Particularly harmful are air currents through the air tightness layer. In this case, a fall below the dew point is always to be expected. The wet bulb temperature, which plays an important role in the air conditioning industry, for example, is a very important parameter in many other areas.
