Weather Meter
SKYWATCH GEOS 11

The SKYWATCH® Geos is specially designed for intensive use in harsh environments.
The SKYWATCH® Geos is a high performance professional instrument benefiting from our 25 years of experience in developing measuring devices. It uses only industry quality components and pressure, windspeed, humidity and temperature sensors that are made in Switzerland.
Functions and specifications
• Air speed measurements: current, average, maximum
• Temperature measurements: current, wind-chill, minimum, maximum
• Humidity measurements: current relative, minimum relative, maximum relative, dew point
• Pressure measurements: QNH (pressure at sea level), QFE,
Altitude (-1000m to +16’000m), Maximum altitude, Density Altitude, Height,
Flight level, Flight finesse, Variometer, Weather forecast
• Time measurements: Clock, Date, Chrono (0.1 sec to 999 h)
• Digital and analogical electronic compass, to the degree
• Data Recording, with time and date stamped: Manual, Historical (continuous recording, even when the instrument is turned off), Automatic (only recording when the device is turned on), Data download on the computer
• Magnetic field level, in µ Tesla unit • High efficient LED micro flashlight
• Backlight • Waterproof metal casing • Mineral glass
• Extra battery as spare included

*Response time for temperature and humidity is highly dependant of the air flow over the exposed sensors. With air flow, response time is within a few minutes to adjust to the ambient temperature and relative humidity. With no air flow, several minutes may be required to adjust properly.
