MK-21 Vibration meter for easy diagnostics
The Checkline MK-21 Vibrationmeter accurately monitors vibrations in all kinds of machinery as recommended by ISO 10816. This Vibrometer will be a great help to you as a monitoring system to indicate when maintenance or repair of your machinery is due.
In addition to standard approaches, the MK-21uniquely 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).
The attractive, ergonomic housing design is extremely compact, lightweight and rugged. It fits comfortably in the palm of your hand and incorporates a back light that illuminates the LCD in poorly lit areas.
- 5 selectable measuring modes: Diagnostic, Displacement, Velocity, Acceleration Peak and Acceleration, as required for a wide choice of vibration analysis techniques.
- Extremely compact, ergonomic and lightweight
- The simple menu setup makes this vibrometer very easy to use
- Powerful magnet-fitted sensor assures dependable mounting on vibrating steel surfaces
- 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.
- Selectable backlit display for dark, hard-to-read locations
