Local gravity calibration is available on all models. Gas Industry Models Standard testers in inH2O or cmH2O are calibrated reference water columns at 20°C (68°F) per ISA recommended practices. Calibration to reference water columns at 60°F per AGA standards is available. Exceptional Performance and Safety Built-In - Floating Ball Operation Self-Regulating Rugged Ceramic Measuring Ball Overhung Weight Carrier Non-Contaminating Test Fluid Closed Cover Operation Ball Valves for Inlet and Outlet Interchangeable Weights NIST Traceable PRODUCT DESCRIPTION The RK tester is a floating ball type, pneumatic deadweight tester. This model is engineered to offer user-friendly features, safe operation, and an optimal performance in the field or in the lab. Self-regulating pressure standard The AMETEK RK Pneumatic Deadweight Tester is a primary standard that produces a pressure by applying force (weight set) over area (the ceramic ball and nozzle). The RK tester is NIST traceable and accurate to ±0.015% using stainless steel weights calibrated to International standard gravity at 9.80665 m/s2 or local gravity as specified. The RK tester is self-regulating with accuracy independent of the operator. The tester utilizes a virtually frictionless ceramic ball floating on a layer of air within a stainless steel cylinder. The RK tester features a quick-leveling system for field or lab setup. The unit may also be mounted on an optional tripod for more convenient setup. The tester may be operated with the cover opened or closed. Weights are located in foam-protective slots in the case.

Model RK® Pneumatic Deadweight Tester FEATURES The following are some of the features and characteristics inherent to the AMETEK RK deadweight tester. Floating Ball While in operation, the RK tester’s ball and weights float freely, supported only by a thin film of air which is virtually frictionless. This eliminates the necessity to rotate the weights during testing and allows the user to concentrate on the instrument calibration. Rugged Ceramic Measuring Ball The floating ball is manufactured from aluminum oxide ceramic - a material with near-diamond hardness. The ball, unlike steel and...
