PRODUCT DESCRIPTION
The TH-DYM3-1 is a portable, mercury-free aneroid barometer designed for high-altitude atmospheric pressure measurement. Its extended 500–1020 hPa range covers the low pressures encountered at plateau and mountain stations where standard barometers run out of scale.
The precision dial movement reads to 1 hPa with an attached thermometer for temperature correction, and the instrument works from -10 to +40°C with no power supply or consumables. Compact and easy to maintain, it is built for remote high-altitude fieldwork.
