The Longacre Air Cylinder Bump Stop Spring Tester - 4000 lb is air cylinder powered allowing for total control of the travel rate either fast or slow. Move fast with the macro valve to compress the spring quickly or use the micro adjustment valve to move very slow you can easily get to .001" for more accurate readings. This is NOT an "air over oil" style hydraulic tester. Those typically have no fine movement control and tend to be slow overall. Which makes for quicker tests and its easier on your arms too!
