Series 200 & 300 Durablock® Solid Plastic Stationary Gages, or draft gages,
Dwyer
are offered in inclined and vertical (well-type) styles for highly accurate laboratory
or general industrial service, for measurement of low range gas and air pressures,
positive, negative or differential. To assure the accuracy required in instruments of this
type, all machining of bores and wells is to the highest standards of precision backed
by Dwyer’s years of experience in the fabrications of acrylic instruments.
FEATURES/BENEFITS
• High-accuracy measurement of low range gas and air pressure suitable for laboratory
or general industry
• Precision built assures device meets the highest standards
• No moving parts mean no calibration or nothing to wear out
• Over-pressure trap prevents liquid from being expelled from gage, preventing
disruption of operation
APPLICATIONS
• Low pressure laboratory and industrial service applications
Exclusive Dwyer® over-pressure safety traps assure that over range
pressures whether gradual or a sudden surge will not force the liquid
out of the gage. Over-pressures simply raise the oat, force the O-ring
over the opening and seal the uid in the gage. When pressure is
reduced, the oat drops down releasing the O-ring safety trap which
allows the gage to continue operation.
