Manometer Series 200 Durablock Solid Plastic Stationary Gauge, Range: .10-0-1.0" w.c.
The Dwyer 200.5 is a solid plastic stationery gage or draft gage with .10-0-1.0" w.c. range. It offers an inclined style 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 fabrication of acrylic instruments.
The Dwyer 200.5 offers a solid block 1" thick acrylic plastic body, which is virtually unbreakable, stable, and free of the danger of distortion. It has adjustable reflective polished aluminum scales with thumbscrew locking for easy zeroing. The M202 also features over-pressure safety traps that prevent loss of fluid due to over-range pressures or surges in pressure. The heavy gauge steel mounting panel is a gray Hammarlund finish. Precision-built assures the device meets the highest standards.
Exclusive Dwyer over-pressure safety traps assure that over-range pressures, whether gradual or sudden surges, will not force the liquid out of the gage. Over-pressures simply raise the float, force the O-ring over the opening and seal the fluid in the gage. When pressure is reduced, the float drops down, releasing the O-ring safety trap, which allows the gage to continue operation.
