Product Description

Fischer Humidity and Temperature - Dial w/ Black Face.

The Durable Fischer HTAB-169 Hygrometer is certified to be accurate within ±3% RH (30 ... 95%), + 1 scale division.

The dial indicates the complete range of 0 to 100% relative humidity. Each instrument has been tested for accuracy at 3 points on the scale for high, medium and low readings. 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.

Gradations are 1% RH and 2° Fahrenheit.

  • Gleaming finish, housing is solid brass, polished and lacquered.
  • Overall diameter 6"
  • Dial 5"
  • Case drilled for wall mounting
  • Black dial with white numbers and letters
  • Manufactured and tested under ISO-9001
  • Accuracy ±3% RH + 1 scale division
Because these are mechanical instruments, they will not hold the ± 3% accuracy on the far ends of the scale (below 20% and above 95%). The measurement of the temperature and relative humidity remains correct if the pressure goes up or down. This is confirmed for the pressure range of 600 … 1200 hPa (mbar) = 8.7 … 17.4 PSI.
