The MK-21 hand held vibration meter accurately measures machine vibration, as recommended by ISO 10816, to alert the user to know when to provide cost-effective machinery maintenance to avoid costly down time, now and in the future. In addition to standard approaches, the MK-21 uniquely checks machinery condition, in the Diagnostic mode, without reference to a chart … as easy as reading a, bb, ccc and dddd on the display - where a = Quite Good (Zone A), bb = Good (Zone B), ccc = Poor (Zone C) and dddd = Bad (Zone D). Condition Zones A,B,C & D cover those vibration velocity ranges noted in ISO 10816 Features
Five (5) measuring modes: Diagnostic, Displacement, Velocity, Acceleration Peak and Acceleration, as required for a wide choice of vibration analysis techniques Compact, ergonomic, lightweight design with simple button keypad and menu make for easy operation Selectable backlit display for dark, hard-to-read locations Four (4) Target Machinery Classes, per ISO 10816, in Diagnostic mode: Classes I, II, III and IV, for machines from less that 15 KW to Large Prime Movers, such as turbo generators and gas turbines with outputs greater than 10 MW Powerful magnet-fitted sensor assures dependable mounting on vibrating steel surfaces
