The Dwyer 201 Durablock Manometer Solid Plastic Stationary Gauge excels in accurately assessing low-range gas and air pressures, whether in laboratory or industrial settings. To assure the accuracy of this instrument, 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. Notable features include integrated over-pressure traps that prevent liquid discharge, thus maintaining seamless operations. Absence of moving components eliminates recalibration and maintenance needs. This gauge features exclusive Dwyer over-pressure safety traps to assure that a sudden surge 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. Tailored to low-pressure applications, it ensures precise measurements, making the Dwyer 201 Durablock Gauge an indispensable asset for your measurement requisites.
