ABBEON HYGROMETERS
The dial indicates the complete range of 0 to 100% relative humidity. Each instrument has been tested at three different positions of the dial at temperatures ranging from 32° to 230°F. The calibration and certification are done under ISO-9001 control.
The bimetallic thermometer on the model HTAB-169 is accurate to±1% of scale and has a range of -10° to 190°F. Graduations are 1% RH and 2° Fahrenheit.
Because these are mechanical instruments, they will not hold the ± 3% accuracy on the far ends of the scale (below 20% and above 80%).
