The latest and best Bob Parker design and successor to the famous Dick Smith ESR.

Welcome our two newest distributors:  Main Electronics (USA & Canada) and Trans Electronic Services (Australia)

  The Blue ESR/Low Ohms Meter    Also see the companion Blue ring tester for FBT/LOPTs and Hi-Q inductors.

Shown with optional stand and croc clips.                                           Visit all of our Distributors of Blue ESR Meter 

Blue ESR/Low Ohms Kit battery not included $79.00    

Fully assembled, tested and aligned including 9 volt battery $119.00

Quality test leads with banana jacks and alligator clips included.  You can add the optional croc clips and/or probes or use your own

Easy access battery compartment.

The easiest assembly ever.  All components are on the solder masked pc board.

On board diagnostics to detect assembly errors

MkII firmware, Bob's latest.

Best battery lifetime, circuits function down to  battery voltage of 5.5 volts

This handy and affordable meter measures capacitor equivalent series resistance (ESR) in the circuit.  ESR is a very important characteristic of capacitors greater than 1 ufd.  This meter makes measurements which are often impossible to check with capacitance meters.  See the electrolytic cap ESR problem for more information on ESR.

Also great for measuring very low values of resistance.

Supplied in kit form with all components, hardware, PCB, case,  and full assembly, test and alignment instructions.  The unit has on board automatic problem sensing that will detect assembly errors.  

Accessories include custom stand, small and large croc clips, probes and battery.
