Choosing among multimeters electrical testers gets tricky when insulation resistance is the main job. The meters all look like handheld testers, but the prices are spread widely, and the differences show up in measurement ranges, included accessories, added functions, and whether a unit is sold new or pre-owned. The right pick depends on how much you want to spend and whether you need a simple megohmmeter or a broader electrical tester.
Quick Take
The BTMETER Digital Megohmmeter is the lowest-priced option with clearly stated insulation ranges. The Megger MJ459 is a low-cost Megger choice. The FLUKE 1503 sits in the middle of the pricing, while the Amprobe MegaTest 1 AMB-45 is the highest-priced unit and comes as a fuller bundle.

Product Notes
Megger MJ459 Insulation Resistance Tester
The Megger MJ459 is the second-lowest-priced option in this group and is sold in used, good working condition. It is a straightforward insulation resistance tester with MPN MJ459, and the lower price makes it appealing if you already know this model. The trade-off is the pre-owned condition, so you are accepting used gear instead of a factory-fresh unit. If you want a simple, low-cost used Megger for electrical work, this is the one to consider. If you prefer a new tester with explicitly stated ranges, the BTMETER Digital Megohmmeter is the lower-priced choice.
Digital Megohmmeter Insulation Resistance Tester for Advanced Industrial 2000MΩ
The BTMETER Digital Megohmmeter is the least expensive option here and the only new tester in the group. It offers 250V, 500V, and 1000V insulation test voltages, insulation measurements up to 2000MΩ at 1000V, AC voltage up to 750V, and DC voltage up to 1000V. The design includes a backlit LCD, data hold, a lock function for continuous measurement, and a shoulder strap. The main limitation is manual-range operation, so you choose the range instead of letting the meter switch automatically. For a new tester with clear ranges at the bottom of the price range, it is a direct answer to the low-price side of the decision.
Amprobe MegaTest 1 AMB-45 Insulation Resistance Tester Megohmmeter, Case & Leads
The Amprobe MegaTest 1 AMB-45 is the highest-priced unit in this group. The case and leads are part of the bundle, along with a carrying pouch, another cable, manual, and CD. This used megohmmeter is in good working condition with a crisp screen and minor handling smudges. Beyond insulation testing, it covers resistance, frequency, temperature, voltage, and capacitance, and includes true RMS, auto power off, and overrange protection. The main barrier is the price, which is significantly higher than every other tester in this group. Choose it when you want one unit with a broad set of functions and the accessories to go with it.
FLUKE INSULATION RESISTANCE TESTER 1503 (P22019407
The FLUKE 1503 sits in the middle of the price range. This used tester is tested and fully functional, with light scuffs and scratches from normal use and a condition rating of 93% very good. If you want a Fluke insulation resistance tester at a pre-owned price, this model is the middle-ground option. The limitation is the used condition and visible cosmetic wear; it is not a new meter. It sits between the low-priced BTMETER unit and the higher-priced Amprobe bundle, so the main question is whether the 1503's tested condition and middle price make sense for you.
Final Recommendation by Use Case
For a shopper who wants to spend the least and still get a new tester, the BTMETER Digital Megohmmeter is the straightforward pick. If you are comfortable with used gear and specifically want a Megger MJ459, that low-cost Megger option fits well. For a mid-priced Fluke model that is tested and functional, the FLUKE 1503 is the match. And if you want a complete kit with a broad feature set, the Amprobe MegaTest 1 AMB-45 is the one to buy. Match the tester to your budget and the kind of work you do, and the right choice becomes clear.
