"Major" Megger Insulation Resistance Testers are the recognized standard in the industry.
"Major" Megger Insulation Resistance Testers are the recognized standard in the industry. The Major Meggers have proven so reliable and popular that they have been reintroduced, generation after generation, with circuitry upgraded to complement the familiar design.
True analog movement remains a popular feature, especially where diagnosis is involved. The trained eye can get much more than just a M¥Ø reading from an analog meter. Similarly, a guard terminal adds a valuable extra dimension when more than just pass/fail testing is desired. With commonly four test voltages, extra range to the resistance measurements, continuity and k¥Ø functions for proofing and troubleshooting, the Major Meggers address the widest range of applications and are the most general models.
Features
Model 212159 — The most basic hand-cranked tester. Dating back to its initial version, this has the longest history and is the most popular model ever on the market. The dependability of this self-contained generator remains unchallenged
Model 212359 — A dual source version, combining line operation and hand-crank, ease and dependability
Model 242459 — Operates on convenient throwaway batteries
Model 212559 — Battery rechargeable by internal charger and powered by 120 volt ac, 50/60 Hz line
Model 212160 — A lower-voltage, lower-range version of the 212159. With a 50 V output selection, it is the model of choice for testing sensitive equipment, subassemblies, and components
Model 210600 — Digital Autoranging Model — For those who prefer digital, this model includes all of the megger series standard capabilities
Model 210170 — High Resistance Model — Offers a greater range (by a power of 10) while providing accurate readings of exceptionally high resistance values. This unit is especially suited for long-term trending of new equipment.
