The HX-500 is a hand-held instrument for measuring moisture in cotton processing and textile production. Four calibration curves are selected according to the material: a pressure sensor for raw cotton, a 21 cm twin-needle probe for cotton bales, and a 2.5 cm or 21 cm twin-needle probe for cotton thread. The instrument is calibrated against the JIS L 0105 oven-drying method, so the readings shown are moisture percentages on a dry basis.
