Quadtech

MegOhm and MilliOhm Meters

Megohmmeters
QuadTech's high resistance megohmmeters include analog megohmmeters, digital megohmmeters and digital ohm meters used for making high resistance measurements or insulation resistance testing on wire & cable, components & materials.

Insulation Resistance Testers
An insulation resistance tester produces a quantifiable value of resistance for the whole of a component's insulation. A test voltage is applied similarily as a routine hipot test, but the insulation resistance tester uses DC or 'direct current.' The measured current and voltage values are used to calculate the components insulation's resistance.

Milliohmmeters
QuadTech's LR2000 milliohmmeter (low resistance ohm meters) are useful for measuring very small resistances. These ohm meters (also referred to as 'ohmmeter' and 'micro-ohmmeter') are used to achieve accurate low resistance measurement values.

On devices such as switches, relays connectors and printed circuit boards, a low resistance measurement ohmmeter or milliohmmeter is recommended as these values require precise data. Micro-ohmmeter and milliohmmeters are perfect for measuring low resistance or conductive characteristics of these components.
