Dead Weight Pressure Gauge Testers
Dead Weight Pressure Gauge Testers
Apex Dead Weight Pressure Gauge Testers are precision instruments for pressure measurement and for the calibration of pressure gauges and other pressure sensitive instruments. Apex testers are accurate, robust in construction, simple to operate, light-weight, and easy to carry to work site. The testers employ the piston gauge principle whereby calibrated weight is loaded on top of a vertically mounted piston of known effective area to balance the upward force of a hydraulic or pneumatic pressure. The tester is self contained and uses manually operated hydraulic pump for generating required pressure. These are available in various ranges 0.2-10/0.5-40/1-100/2.5-160/5-250/1-400/1-600/5-1000 kg/sq cm both in single and dual ranges. Other pressure and vacuum calibrating instruments are also available such as vacuum gauge testers, combined pressure and vacuum gauge testers, liquid column manometers, etc.
