Measur ing Ins t rument s
Precision Hair Hygrometer
Hygrometer for measuring the
relative air humidity, consisting
of a round plastic housing with a
human hair as the measuring ele-
ment. The specially treated hair
exhibits an almost inertia free
response to changes in humidity.
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, highly-evacuated metal cans which deform in response to changes in the air pres-
sure. 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

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 radio-controlled clock with date function. Supplied with one external tempera-
ture 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
Internal temperatures: 0°C … +60°C
