In the multimeters electrical testers aisle, an insulation resistance tester-also called a megohmmeter-checks the health of wire, motor, and cable insulation by applying a set voltage and reading the resistance. The choice here is familiar: a brand-new budget tester with multiple test voltages versus a used, Fluke-branded unit. The BTMETER Digital Megohmmeter takes the budget side, while the Fluke 1503 Insulation Resistance Tester takes the used, model-specific side.
Quick verdict
If you need a working insulation tester without a large outlay, the BTMETER is the straightforward pick. If the Fluke 1503 is the unit you need, the higher price may be worth it.
At a glance
| Product | Listed price | Price bar | Condition | Key details |
|---|---|---|---|---|
| BTMETER Digital Megohmmeter Insulation Resistance Tester | $39.89 | New | 250V/500V/1000V test voltages; insulation to 2000MΩ; AC voltage 0-750V | |
| Fluke 1503 Insulation Resistance Tester | $199.99 | Used | Model 1503; includes factory cords and attachments; light cosmetic wear |
Where each product wins
The BTMETER wins on price. For a first megohmmeter or occasional use, its lower list price makes it an easy yes. The Fluke 1503 wins on model specificity and tested functionality. For a technician whose work order names a Fluke 1503, that tested status carries more weight than the budget difference.
Product notes
BTMETER Digital Megohmmeter Insulation Resistance Tester
At $39.89, this tester keeps the price low while covering the three insulation test voltages of 250V, 500V, and 1000V. It measures insulation resistance up to 2000MΩ, handles AC voltage from 0 to 750V, and reads frequency in the 40Hz to 400Hz range. The backlit LCD makes values readable in darker areas, and the lock function lets you keep the test button engaged hands-free. A shoulder strap is included for carrying the meter outside. Because it is a manual-range unit, you select the test voltage yourself, so you need to know the right setting before pressing the test button. It is described as new, which avoids the wear-and-tear questions that come with used equipment. For a budget-minded shopper in the multimeters electrical testers category, it is the simpler, lower-risk financial choice.
Fluke 1503 Insulation Resistance Tester
The Fluke 1503 is listed at $199.99, a significant jump from the BTMETER. What that extra money buys is a specific model with a 93% condition rating and a description that says it has been tested and is fully functional. It also includes the factory cords, cables, and attachments, so you can measure right away without rounding up accessories. The trade-offs are visible: the description mentions normal cosmetic wear, light scuffs and scratches, and the original box may or may not be included. If your work calls for a Fluke 1503, the model number and tested working status carry real weight. For someone who only needs insulation readings now and then, the used-unit uncertainties are harder to justify.
Final choice by use case
Choose the BTMETER if you want a new tester that fits a modest budget. Choose the Fluke 1503 if the model designation matters for your work and you can accept the higher list price.
