Products/Services for Assmann Psychrometer
-
Hygrometers and Humidity Measurement Instruments - (604 companies)...or impedance style sensors, a material absorbs moisture, which changes its resistivity or impedance. In strain gage instruments, a material absorbs water, expands and is measured with a strain gage. Psychrometers, often called wet/dry bulbs, measure...Form FactorVariables MeasuredCompensation -
Weather Instruments - (328 companies)Weather instruments are designed to measure one or multiple components of weather including wind speed and direction, rain or snow fall, solar radiation, temperature, pressure and humidity. -
Hall Effect Proximity Sensors - (131 companies)Hall effect proximity sensors are used to detect the proximity, presence or absence of a magnetic object using a critical distance. -
Thermistors - (331 companies)Thermistors are thermally-sensitive devices whose electrical resistance varies with temperature. Unlike RTDs and thermocouples, thermistors do not have standards associated with their resistance vs. temperature characteristics or curves. -
Humidity Controllers - (128 companies)Humidity controllers monitor and maintain proper humidity levels in environmental test applications, food storage areas, and electronic equipment rooms. -
Humidity Transmitters - (203 companies)...a desiccant. Infrared (IR) instruments use the infrared spectrum to measure the absorption of moisture. With microwave-based devices, the amplitude and phase of a microwave signal is affected directly by the amount of moisture in a material. Psychrometers...
-
Moisture Meters - (874 companies)Moisture meters are used to measure the moisture content in bulk solids, liquids and gases.

Standard psychrometers: a matter of (p)references
The present work gives the results of comparisons between a standard mirror dew-point meter and several psychrometers of different types. amongst which the WMO referenceand the Assmann psychrometer .

The present‐day accuracy of meteorological instruments
Realizing this, Holtzrnann made many experiments to dis- cover how much a single reading (of an Assmann psychrometer ) might be expected to differ from the mean of forty readings at five- second intervals.
-
An oscillating psychrometer for micro-meteorological purposes
As no constant humidity room was available, the psychrometric differences obtained with the oscillating meter and an Assmann psychro- meter were compared in unconditioned air.
-
A portable temperature‐gradient indicator
SIMPLESTTYPEOF INDICATOR The simplest method of obtaining differences of temperature is, of course, by means of two Assmann psychrometers or sling psychrometers.

A NOTE ON THE CLIMATE INSIDE A MEDIAEV AL CHAPEL
Every three or four weeks the instruments were carefully calibrated against Assmann psychrometers .

FIELD STUDIES OF MOUNTAIN WEATHER IN SNOWDONIA
Experiments need to be made, over different types of ground and in both sunny and cloudy weather, to compare readings from a whirling psychrometer with those from the shielded thermometer of an Assmann psychrometer .) .

What is the primary difference between a sling psy- chrometer and Assmann psychrometer ?
-
Perry's Chemical Engineers' Handbook, Eighth Edition > PSYCHROMETRY
For an Assmann psychrometer at near-ambient conditions, this is approximately 10 percent.

Instruments for micro‐meteorology
Calibration in full sunlight against an Assmann psychrometer showed that the shield was adequate except when a low sun shone into the end of the unit, or when ventilation was below 1 m/sec.
