| The
Shaw automatic dewpoint meter makes spot moisture checks of air and
gases with ease not possible before. Other instruments typically require
purging and delays as long as several hours before reading. Automatic
drydown of the dewpoint meter takes a few minutes: 5 to 10 in most
cases. Thus, the instrument is always left ready for the next test.
SPEED
Quickly shows on the dial the exact amount of moisture in
"dry" air or gas.
AUTOMATIC MEASUREMENT
Self extending head takes up to 20 liters a minute for clearing pipe
work without wetting the test chamber. Flow rate has no effect.
AUTOMATIC DRYDOWN
The world patent automatic drydown between tests can save hours or
even days at a time.
It cannot be copied, so only the shaw automatic dewpoint meter is always
ready to check dryness down to less that one part per million of water
vapor.
AUTOMATIC CALIBRATION
Adjust for full scale reading while sensing room air moisture. Contact
us for details
RELIABLE
The long term stability of the unique, world patented, Shaw 10
micron, gold sensor element, which has taken twenty years to perfect, is
the reason why no correction or adjustment knobs are used. Average life
of sensing devise is ten years.
SIMPLE
Unscientific staff are happy with the absense of knobs, cooling
calibrating and servicing, as needed by other methods, Not sensitive
to flow rate. No purging needed. Results are 100% repeatable.
PORTABLE
The batteries (six C size) last more than a year in this easy to
carry and use anywhere portable hygrometer.
