SKYWATCH® atmos Temperature & RH Anemometer

From Instruments Direct, the new and improved Skywatch Atmos anemometer, is a user-friendly, multi-functional meter designed for measuring wind speed, temperature and humidity. The comprehensive meter provides balanced instant readings without compromising on performance. Constructed from high-quality lightweight plastics the Skywatch Atmos anemometer floats even if accidentally dropped into the water. Easy to use, this extremely accurate instrument is ideal for farming, agriculture and any avid outdoor enthusiast.

Robust in design, the Skywatch Atmos uses a multi-directional rotating turbine to deliver precise readings according to Swiss standards, even at low speeds. The innovatively designed turbine allows exact measurements to be collected even without being pointed directly into the wind. An aluminium bottom plate allows the Atmos anemometer to be mounted onto a tripod for even more versatility.

With only 4 control keys the Atmos anemometer is extremely easy to use. Simply select from one of the 3 functions, wind speed, temperature or humidity and select the mode you wish the data to be displayed. The modes are then displayed in specific units of measurement. For wind speed, km/h, mph, m/s, fps, knots and bft. For Temperature measurement, °C, °F, °C perceived and °F perceived. For humidity %rH. With an LCD display and backlight function, all recordings are clearly shown on the front screen, even in low light conditions.

Rotating vane anemometers are used to measure environmental conditions quickly and accurately. The information and data they provide are vital in a wide range of applications and environments. They are essential for reporting, forecasting and planning and more importantly health and safety. Some of the more common are

• Farming – indicating weather conditions before crop spraying
• Sailing, boating and windsurfing – determine wind speed, wind direction and gust
• Weather stations and meteorological studies – atmospheric conditions


Q - Is there a recommended replacement battery?
A - Yes, the Atmos Handheld anemometer uses a 3V CR2032 lithium battery for its power supply. See RS part number 866-0672

Supplied with

Protective cap for the impeller and carry pouch.
