Constant test voltage across measurement range
ensures accurate and realistic tests - True Megohmmeter®
Autoranging MΩ, kΩ and
Ω ranges
Designed for harsh environments: offshore, mining,
heavy-duty field, industrial, and military use
Extra rugged cast aluminum case; O-ring sealed
against rain, water and dust; aluminum lid
Compact, self-contained package; folding crank
Large direct-reading scale
600V test voltage range (safety check)
The Model 1210N is a compact, self-contained, hand-cranked
True Megohmmeter. This practical and dependable instrument is designed for a broad range
of plant and field service applications.
The easy hand-cranked operation provides a steady, rectified DC voltage output across the
entire range for consistently reliable readings. In addition, the Model 1210N also permits
resistance testing to 500kΩ and continuity testing to 100Ω.
The 600V test voltage range is to perform safety checks to confirm that the sample is
fully discharged and not connected to an energized circuit.
