This portable digital milli-ohmmeter is a practical instrument for low resistance measurement, ideal for use in multiple industries workshop, field\n or test labs.
\n
This milli-ohmmeter is of rugged construction contained in a sturdy plastic case. The Series 4000 has many advanced features, including auto ranging,\n forward and reverse current measurement with auto average, true current zero, protection up to 415 volts rms, digital calibration and long scale\n length, 4000 count and auto power down to maximise battery life.
\n
The Series 4000 milli-ohmmeters are supplied ready for immediate use with batteries and measuring leads, no extras are normally necessary.
\n
\n
\n
Fast response hand held True 4-terminal measurement ohmmeter
The model 4001 includes temperature compensation, with preset coefficients for copper and aluminium plus user settable coefficients for other materials.\n Temperature measurement over the range -50...+800 deg. C is also available.
