Dead weight pressure gauge tester

Apex Control Instruments, from Delhi, offers dead weight pressure gauge testers that are precision instruments for pressure measurement and for calibration of pressure gauges and other pressure sensitive instruments. Apex testers are accurate and robust in construction, simple to operate, light in weight and easy to carry to sites. These testers employ the piston gauge principle whereby weight of known mass 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 a manually operated hydraulic pump for generating required pressure. These are available in various ranges such as 0.2-10, 0.5-40, 1-100, 2.5-160, 5-250, 1-400, 1-600 and 5-1000 kg/sq cm, both in single and dual ranges. Other pressure and vacuum calibrating instruments such as vacuum gauge testers (700 mm Hg - 0), combined pressure and vacuum gauge testers (100 Kg/sq.cm, 0-700 mm Hg), low pressure dead weight testers (50 mbar to 1000 mbar), comparison test pumps (various ranges upto 1500 Kg/sq.cm) and oxytester attachment (upto 400 Kg/sq.cm.) are also available.
