Megger BM21

SKU : 7128
In Stock : 1
Price: AUD$1400

Please note that this 5kV Megger does not come with a lid or accessories. One of the corners has a couple hairline cracks and one of the four lid hinge posts is broken - see photos.

The unit comes with two new internal batteries and is in good working order apart from the cosmetic issues.

"The series has been extended with three analog/digital instruments; the BM11D, BM21 and BM25. These instruments show results and test options on a large, clear analog/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 unit switch a variable test voltage in 25 V steps. These top of the range units also allow measurement of resistance to 5 TΩ,leakage current to 0,01 nA and can display capacitance at the end of a test to 10 µF."
