     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 +0.05% using stainless steel weights calibrated to international standard gravity at 980.665 cm/sec2. +/-0.025% and +/-0.015% accuracy are also available.

     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 cast-metal base with a quick-leveling system for field or lab setup. The unit may also be mounted to 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.

 

Standard Delivery:

  • • RK Tester 
  • • Stainless Steel Weights, Range Specific
  • • Hard Carry Case 
  • • NIST Traceable Calibration Certificate (Data Optional)
  • • User manual
