This fine German made instrument features barometric pressure (inHg and mbar), temperature (degF) and humidity (%).

The dials feature a bezel made of stainless steel, with a mineral glass cover.

About the Human Hair Hygrometer:: This instrument measures the relative humidity of the atmosphere with high precision (These are 3%, to get to 1% costs more than $1,500). Relative humidity is a crucial factor in weather analysis and forecasting and human comfort. The data are also crucial to the safe storage of many products and instruments.

This purely mechanical instrument has been a prized product of the Fischer Precision Instrument Company for more than 60 years. It has no electronic components. The sensor element is human hair whose length is sensitive to the humidity in the air. For a given tension on the fiber bundle, the length increases with increasing relative humidity. Changes in its length are then magnified with precision gears to display the relative humidity of the air.

Installation: Relative humidity is closely correlated to and dependent upon air temperature, so it provides best data when not exposed to rapidly changing temperatures. For the best measure of the humidity, avoid placing the instrument in direct sunlight or in line with strong breezes. Locate the instrument in a place that best represents the average temperature of the local environment. Avoid outside walls that might be cooler than average, and avoid direct exposure to heat sources that would be warmer than average.

Healthy room environment: It is often considered that 40% to 60% is a healthy and comfortable relative humidity range, and with a hygrometer showing the actual value you may find that added moisture in the winter would be beneficial.

The barometer operates to about 3,000 feet altitude (do not order if you live above 3,000 feet).

High Elevation Barometers: We do not stock Fischer barometers which are adjusted/calibrated for elevations of 3,000+'. If you require a high elevation barometer call our sales staff 480 346 3380 option 1 and request a quote. High elevation barometers will be custom ordered, drop shipped from Germany and can not be returned unless defective.

About Fischer Instruments...

The Fischer factory for precision instruments was founded in 1945 by aircraft engineer Kurt Fischer, in a small village in the Erzgebirge called Drebach.

Still owned and operated by the Fischer family, the experienced engineers and craftsman have designed quality instruments for measuring weather and climate.

Precise instruments, well balanced, and well crafted to the finest detail.
