PRODUCT DESCRIPTION
The TH-DHM2 is a mechanical ventilated psychrometer for observing air temperature and humidity by the wet- and dry-bulb method. A hand-driven fan draws air over the bulbs at more than 2.5 m/s, the condition needed for accurate psychrometric readings, across 10–100%RH.
With no electronics or batteries, it remains a dependable reference instrument for meteorological observation and calibration checks.
