Rain gauge
This transparent, conical container
is made of a totally synthetic material,
and has a stand so that the
rain gauge can be placed on a pole
in the open air.
Graduation up to 40 mm / m²

Precision Hair Hygrometer
Hygrometer for measuring the
relative air humidity, consisting
of a round plastic housing with a
human hair as the measuring element.
The specially treated hair
exhibits an almost inertia free
response to changes in humid ity.
Wall mountable.
Measuring range: 0% – 100%
relative
humidity
Temperature range: - 35 °C –
+ 65 °C
Reading accuracy: ± 5%
Diameter: 100 mm

Demonstration Aneroid Barometer
Barometer for measuring air pressure and demonstrating how an aneroid
barometer operates. The measurement system consists of two flat, highlyevacuated
metal cans which deform in response to changes in the air pressure.
This deformation is indicated by a pointer. The pointer mechanism
and metal cans are situated behind a glass cover for easy observation.
By pumping the attached rubber ball the action caused by the air pressure
changes can be demonstrated.
Measuring ranges: 955 mbar up to 1070 mbar, scale division 1 mbar
715 mmHg up to 800 mmHg, scale division 1 mmHg
Scale diameter: 120 mm
Housing diameter: 130 mm
Weight:
650 g

Wireless Weather Station
Weather station with wireless detection of external temperatures from
up to three sensors situated at distances of up to 25 m. Display of internal
temperature and humidity. Features switchable °C/°F display, min/max
function, weather forecasting, trend displays for air pressure and radiocontrolled
clock with date function. Supplied with one external temperature
sensor, two 1.5-V AA batteries and two 1.5-V AAA batteries. Silver/grey
housing. Can be suspended or set up on a surface.
External temperatures: -30°C … +70°C
