Features and Specs
  • Spot tests and diagnostic insulation tests
  • Simplicity and Ease of Use
  • User safety features
  • Unique rugged casing
  • Analogue and Analogue/Digital Displays
  • Wide range of test voltages

The traditional BM11 instrument became the industry standard 5 kV tester. It is battery-powered, housed in a rugged case and has a large, simple white-on-black scale. The series has been extended with three analogue/digital instruments; the BM11D, BM21 and BM25. These instruments show results and test options on a large, clear analogue/digital scale for both practicality and precision. A built-in timer makes both spot tests and PI testing easier to carry out. They are powered by a built-in rechargeable lead-acid battery which can be charged directly from any supply from 95 V to 265 V. All testers incorporate a guard terminal to allow surface leakage to be removed. Pre-set standard test voltages at 500 V, 1000 V, 2500 V and 5000 V are supplemented on the BM21 and BM25 units with a variable test voltage in 25 V steps. These top of the range units also allow measurement of resistance to 5 T½, leakage current to 0,01 nA and can display capacitance at the end of a test to 10 µF.
