Impeller anemometer with backlit / 10 cm diameter impeller / for measuring various parameters / parameters / extreme value measurement / HOLD function / auto power off / Low battery warning indicator 
 
The impeller anemometer is a measuring instrument for various wind related parameters. It has got an impeller diameter of ten centimeters. Moreover, if required, it is possible to order a set of flow hoods which provide a fast and reliable method which helps to use the 100 mm large impeller head optimally. The flow hoods can be ordered only as a set which consists of one round and one square flow hood. The round flow hood comes with a diameter of 210 mm and the square flow hood has the dimensions of 346 x 346 mm. This allows checking ventilation systems, air conditioning systems or similar with the help of the flow anemometer. For that purpose the flow hood is mounted on the impeller anemometer and then the whole construction is placed on the air source to be tested. The rubber at the end of the flow hood ensures that the checked chambers are closed. 
 
The impeller anemometer PCE-VA 20 allows measurements of wind speed, flow, temperature, relative humidity, dew point and wet bulb temperature. This is a versatile environmental meter, which provides extensive measuring results. The impeller anemometer also provides extensive features such as an extreme value measurement, HOLD function, backlight, automatic power off and a low battery charge warning function. It all makes it and as much easy and comfortable as possible for the user.
