EM 890 is an instrument for measuring environmental conditions. The HVAC meter gives you an accurate measurement very quickly. Due to the small dimensions and the low weight, this HVAC 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 HVAC 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.
