| The Hand Held Anemometer is a three cup battery operated Anemometer with digital readout (LCD) . It is handy for measurement of wind speed at locations where wind installations are absent as well as for approximate calibration checks on installed field Anemometers. The digital reading is normally in Km/h. However if required knots or meters/sec direct reading can be provided. The unit comes with either dry cells or rechargeable battery pack i.e. nickel cadmium cells (option). If NiCad cells are used then a battery charger is also provided. This comes packed in a carrying case. |
