Propellers for wind mills
Sturdy plastic propellers originally designed for model
aircrafts, but when mounted on 12V motor/generator,
2025.00, they will act as Wind Mills. They do not provide
much power, but sufficient for student measurements.

Solar measuring instruments
Pyranometer
4890.00 This instrument is intended for the measurement of the
direct solar irradiance. The output signal is temperature
compensated, and each instrument is individually cali-
brated. The output signal is directly proportional to the
global solar irradiance in watt per square meter. An out-
put signal of about 160 millivolts corresponds to an ir -
radiance of 1000 W/m
2
. All components are weather pro-
tected so that the instrument is suitable for mounting
outdoors. Size: 10 x 10 x 2.5 cm.
Output signal: 0 - 200 mV
