Blue ESR/Low Ohms Meter
This is the fully-assembled, cablibrated and tested Blue ESR/Low Ohms Meter
The latest and best Bob Parker design and successor to the famous Dick Smith ESR/Low Ohms Meter. 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.
