New delhi-based ravika engineers manufactures yantrika brand dead weight pressure gauge tester is manufactured by new delhi-based ravika engineers. This weight tester is of +/- 0.03 percent accuracy. Following are some of the technical features of these dead weight testers: these testers are provided with fine quality pistons, which are artificially aged, highly accurate and have frictionless rotation. Motorised rotation is also available. Weights are available in ss and phosphated ms. Sphated ms as per requirement. The weights are of annular ring design and are loaded on a carrier bell designed to lower the centre of gravity of weights, which leads to a much better performance levels. The ranges of the dead testers varies andvarious ranges are available up to 750 kg/cm2, and in any unit of calibration such as bar, kpa, mpa, psi. Top loading type testers of accuracies +/- 0.1 and +/- 0.06 percent, comparators and very fine master gauges of accuracies +/- 0.5 and +/- 0.25 percent are available. Electrical motor rotation for free-piston and weights at speeds of approximately 30 rpm are provided.
