On this side of the pond they were made by Anatek until the owner was killed in an accident, then the series (now called the Blue ESR) is made by Alltronics and sold by dealers such as I. These all use Bob's licensed code, just different box and PCB layouts.

The only caveat is to discharge the capacitor first before testing. The
meter does not like anything over 50VDC across the probes...tends to let
the smoke out.
You can use the Blue ESR meter to check the internal resistance of
batteries - I suspect one could use that info to build a chart of
remaining life in a lead acid battery or ni-cad, but I never tried that.
