PRODUCT DESCRIPTION
The TH-HM3 is an electric ventilated psychrometer that measures air temperature and humidity by the wet- and dry-bulb method, with a motor-driven fan holding ventilation at 2–3 m/s for repeatable readings. It covers −26 to 51°C with 0.2°C accuracy over 10–100% humidity.
Steady electric ventilation removes the reading variation of hand-aspirated instruments, suiting it to fixed observation points.
