Megger has been widely acknowledged for being the pioneer of insulating testing devices with over centuries of experience. Where today the qualities of electrical devices are seen degrading with little use in time, mostly due to insulation breakdown, it is for these testers that we tend to cope up with the failure. These testers apply a regulated DC voltage across the insulation and measure current flow through it applying ohm's law to calculate insulation resistance.

Megger has a considerable range of insulation test equipment of 5 &10 kV to choose from. All these Megger Insulation Testers provide the engineers and electricians versatility and quality like never before. And among such varieties of brilliantly crafted Insulation Testers, we bring you one such model of excellence - the Megger BM5200.

The Megger BM5200 tester is an instrument running on battery (Powered by eight 1.5 V IEC I.R6 (AA) cells), with both analogue and digital displays. The instrument works on three Insulation Resistance Test Modes, namely the Insulation mode, the Polarisation ...
... mode & the Variable Time Test modes. For capacitive test objects, the instrument is designed such that it automatically discharges through an internal resistor and indicate voltage across the terminals. The DC insulation tests are performed atfive effective test ranges namely 250V, 500V, 1000V, 2500V & 5000V.Also one has the choice of choosing between AC and DC (including frequency) voltmeter functions. Further a Guard terminal is provided to shunt surface leakage currents.

SOME FEATURES AND BENEFITS:

• Compact, rugged insulation tester
• Easy operation and voltage range selection.
• AC and DC voltmeter
• User settable IR test timer
• Soft carry case for instrument and leads
• Quick start and full user guide.
• Design safety features include high voltage warning indicator, external voltage display after IR test, automatic discharge of reactive loads and test leads.
