Analog hygrometer 11101

for hyperbaric chamber

NIST certification available. The specially treated human hair of the Fischer hair hygrometer 111.01 is insensitive to temperature (temperature range -35 to +65 °C, -30 to 130°F ) and responds quickly to changes in humidity. Measuring range 0 to 100 % relative humidity Accuracy ± 3 % RH + 1 graduation Graduation 1 % RH Stainless steel case, diameter 4 in. In temperatures up to +80°C (176°F) only high relative humidity will be indicated. In medium to high relative humidity the accuracy of our hygrometers is ±3% + 1 graduation. In low humidity it is ±5% + 1 graduation after regeneration.
