The easy-to-read 5-inch dial indicates the temperature in a range of 20¡Æ to 120¡Æ Fahrenheit or 0¡Æ to 50¡Æ
Temperature/Humidity
Indicator
The Model HTAB-176 Hygrometer is certified to be accurate within ¡¾ 3%
RH and 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¡Æ to 230¡ÆF. The bi-metallic
thermometer is accurate to 1% of scale with a range of -20¡Æ to 100¡Æ
Centigrade and 0¡Æ to 210¡Æ Fahrenheit.
This humidity indicator has a 1-year guarantee and a 5-year warranty.
Temperature Indicator
The easy-to-read 5-inch dial indicates the temperature in a range of 20¡Æ
to 120¡Æ Fahrenheit or 0¡Æ to 50¡Æ Centigrade. The pointer actuated by a
bi-metallic strip reads with an accuracy of 1% of scale. Comes with a
one-year guarantee and five-year warranty.
Features
for Temperature/Humidity Indicator
Both
the humidity and temperature are directly read without any
calculations whatsoever
Solid
6-inch overall brass case drilled for wall mounting
Color
differentiated 5-inch dial with black letters and numbers
and a red pointer
Principle
of Hygrometer Operation
An
internal DUROTHERM element expands as humidity increases and
contracts as humidity decreases. This expansion and
contraction is mechanically linked through precision
bearings and gears to the humidity pointer. The unit is
completely self-contained.
Calibration:
A calibration screw is accessible through a slot in the case
for periodic calibration to a known humidity standard.
