Key Details
| Detail | Product information and buyer relevance |
|---|---|
| Brand | DaierTek. Useful for matching the exact gauge line. |
| Product type | Digital voltmeter gauge. This is a voltage display for DC battery monitoring. |
| Measuring range | DC 8-48V. Compare this with the voltage range you need to monitor. |
| Stated use | Widely used with 12V and 24V DC systems. Check that your application matches the intended voltage setup. |
| Display | Blue LED digital display with a 3-bit readout. |
| Accuracy | 0.1V accuracy is stated. This matters if you want a finer voltage readout. |
| Mounting | 1 1/8 inch hole with a nylon retaining nut. Confirm the opening size before choosing an offer. |
| Water resistance | Waterproof design is stated. If moisture exposure matters, compare the exact installation setting and sealing needs. |
What to Compare Before Buying
- Voltage range: The meter is stated for DC 8-48V. Make sure the system you want to monitor falls within that range.
- Mounting hole size: The required opening is 1 1/8 inch. Check your panel cutout before purchase.
- Display style: This model uses a blue LED digital display. Compare that with your preference for visibility and panel layout.
- Installation space: The gauge is panel-mounted, so the front opening and rear space both matter.
- Intended system: It is described for car, boat, marine, motorcycle, truck, ATV, UTV, auto, camper and caravan use. Match it to your own DC setup.
What Else You May Need
A correctly sized panel opening is needed for installation. If your panel does not already have a 1 1/8 inch cutout, you will need a suitable mounting location prepared for the gauge.
Before You Decide
Confirm the DC voltage range, the 1 1/8 inch mounting hole size, and the blue LED display style before choosing an offer. If moisture exposure matters in your setup, review the stated waterproof design against the way you plan to mount it.
