Quick Verdict
When you're comparing multimeters and electrical testers for insulation resistance work, the choice comes down to a new, lower-priced model with specified ranges versus a used unit from a specific series. For most shoppers, the BTMETER Digital Megohmmeter is the pick because it is new and costs less. If the exact Megger MJ459 model matters more to you, the Megger unit lets you match that model, but it costs about USD 20 more.

Where the BTMETER Wins
The BTMETER Digital Megohmmeter wins for shoppers who want a new meter at a lower price. It lists test voltages, an insulation resistance range, and AC and DC voltage ranges, so you know what you are working with before you buy. It also includes a manual range setting and 1999 counts, which can be helpful for hands-on insulation checks. If you are deciding based on price and a fully specified product, this is the stronger choice.
Where the Megger MJ459 Wins
The Megger MJ459 wins when the exact model number matters. This unit is specifically an MJ459, so it can match a replacement need or a test setup that already calls for that model. It is described as used and in good working order, which is worth weighing against the higher price. If you are looking for an MJ459 and not just any insulation resistance tester, the Megger side is the one to choose.
Product Notes
BTMETER Digital Megohmmeter Insulation Resistance Tester for Advanced Industrial 2000MΩ
This new BTMETER unit is priced at USD 39.89 and is the lower-cost option here. It has a stated test voltage set of 250V/500V/1000V and an insulation resistance range of 200MΩ to 2000MΩ, along with AC voltage measurement from 0V to 750V and DC voltage from 0V to 1000V. The product also lists manual range and 1999 counts, a backlit display, data hold, and a lock function for continuous measurement. Choose it when you want a new meter with clearly laid-out ranges. The limitation is that this is a BTMETER megohmmeter, not a Megger MJ459, so it cannot satisfy a shopper who needs that exact model.
Megger MJ459 Insulation Resistance Tester
The Megger MJ459 is a used unit with an MPN of MJ459, listed at USD 59.99. Its description says it is in good working order. Choose this one if you specifically want a Megger MJ459 and are willing to accept a used tester. The advantage of the higher price is model specificity: you are buying the MJ459 rather than a generic digital megohmmeter. The trade-off is the used condition and the price gap of about USD 20 over the BTMETER. That makes it a better fit for someone who prioritizes the exact MJ459 model over a new meter.
Final Choice by Use Case
- Choose the BTMETER Digital Megohmmeter for a new insulation resistance tester with a lower listed price and a clearly specified set of ranges.
- Choose the Megger MJ459 when you need the exact MJ459 model and are comfortable with a used unit described as in good working order.
