Choosing between these two used power quality tools starts with one question: how will you take the measurement? In the power meters energy management category, one option is a dedicated power meter, and the other is a power quality meter that can read DC current. Their listed prices sit at opposite ends of the range: the Schneider Electric PM8240 comes in at USD 412.50, while the Fluke 345 is listed at USD 1,199.99. That makes the Schneider 66% below the Fluke in this comparison.
Quick Verdict
Choose the Schneider Electric PM8240 if you want a dedicated power meter at a lower listed price. Choose the Fluke 345 if you need its DC current measurement capability and can accept the higher listed price.
Comparison
| Product | Listed Price | Relative Price | Condition | Type | Key Capability |
|---|---|---|---|---|---|
| Schneider Electric PM8240 Power Quality Meter PowerLogic METSEPM8240 Used | USD 412.50 | Used | Power Meter / Power Monitoring Module | PowerLogic PM8000 model | |
| Fluke 345 Single Phase Power Quality Clamp Meter DC Current 2000A | USD 1,199.99 | Used | Clamp meter | Single phase, DC current up to 2000A |
Where Each Product Wins
- The Fluke 345 is the pick when you need the type of measurement this meter provides, and the DC current range is the headline reason.
- The Schneider Electric PM8240 is the pick when you want a power meter / power monitoring module and prefer the lower end of the price spread.
Product Notes
Schneider Electric PM8240 Power Quality Meter PowerLogic METSEPM8240 Used
This used Schneider Electric unit sits at the lower-priced end of the comparison, which is its main draw. It is a power meter / power monitoring module with a PowerLogic PM8000 model designation, so it fits projects that need a dedicated meter rather than a clamp-style tool. Both listings carry used condition, so the condition isn't what separates them; the price and the meter type do. The price difference gives this listing a clear advantage for buyers who don't need clamp-style readings. The limitation is that it is not a clamp meter, so it can't capture the clamp-style single-phase DC current reading that the Fluke 345 is built for. If you don't need that clamp function, this is the lower-priced route.
Fluke 345 Single Phase Power Quality Clamp Meter DC Current 2000A
The Fluke 345 earns its higher listed price through a very specific capability: it is a clamp meter that measures DC current up to 2000A in single-phase configurations. That makes it the right choice when you need to test power quality by clamping around a conductor rather than relying on a dedicated power meter. The clamp design is what separates it from the Schneider option. The trade-off is cost: this listing sits at the top of the price range and still carries used condition, so you're paying more for the clamp design and DC range. If those capabilities match the work you do, the higher price is easier to justify. The limitation, plainly, is that it costs significantly more than the Schneider option.
Final Choice by Use Case
Choose the Schneider Electric PM8240 for a dedicated power meter / power monitoring module at a lower listed price. Choose the Fluke 345 when you need a clamp meter with DC current capability up to 2000A and can work with the higher listed price.
