---

Portable Vibration Meter for Machinery Diagnostics

---

Vibration monitoring in accordance with ISO 10816

---

Portable, Compact and Light Weight

---

The Checkline 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
