  • Whirling Hygrometer


    Whirling Hygrometer - Overview

    The whirling hygrometer also known as a sling psychrometer is made out of two thermometers mounted on a frame which rotates around a handle, so it can be whirled in the air by hand. One thermometer is covered with a tight-fitting muslin sock which is kept wet by distilled water. This type of thermometer is known as the wet-bulb thermometer. The other is the dry-bulb thermometer as it is exposed to the atmosphere directly. In air with less than 100 per cent relative humidity, the wet bulb will display a lower temperature than the dry bulb and is known as wet-bulb depression. A special chart is used to convert the wet-bulb depression to relative humidity or the relative humidity can be determined by correlating the readings with those on a simple slide rule, which is supplied with each instrument.

    Whirling Hygrometer - Features

    • Made in accordance with BS2842
    • Housed in a yellow plastic case with folding handle
    • Available in Red Spirit
    • Supplied with Hygrometric tables, spare wick and instructions
    • No electronics and therefore great for us in mines

    The HP22 is a versatile hand-held indicator that displays relative humidity, temperature and a variety of calculated parameters such as dew or frost point based on the measurements of a HygroClip2 plug-in probe.

    Probe selection is based on the application. Depending on the HygroClip2 probe model, the measuring range is within 0 to 100 %RH and -100 to 200°C (-148 to 392°F). The HygroClip2 probes feature durable sensors and consistent performance. All HygroClip2 probes can be hot-swapped to facilitate routine calibrations.

    The HP22 indicator offers extensive settings and functions that can be enabled and configured by the user either directly from the keypad or with the ROTRONIC HW4 software.
