Product description
The WONDERSUNM digital caliper has a stainless steel body and measures across a 0-12" / 0-300 mm range. Its large LCD screen makes the reading easy to see while you work.
Switch between millimetres, inches and fractions on the display, and set zero at any position. That makes it straightforward to take a fresh measurement from a chosen reference point.
Use the caliper for inside, outside, depth and step measurements. The two sets of jaws and the depth probe support different checks with one tool, whether you are working on a DIY project or taking measurements for professional tasks.

The display conversion is useful when a project switches between metric and imperial measurements, or when a dimension is easier to read as a fraction. Rather than moving between separate tools for each format, you can take the measurement and select the unit that suits the task. The zero-setting function also lets you establish a reference point wherever it is useful for the measurement.
How to use it
Position the jaws around or inside the part for an outside or inside measurement. For depth, use the probe, the caliper also supports step measurements. Read the result on the LCD, then choose millimetres, inches or fractions as needed. Setting zero at a selected position provides a practical starting point for a new measurement.
For example, when checking a component during a home repair, you can measure its outside dimensions with the jaws, then use the depth probe for a recessed area. The large screen keeps the readout visible, while the range accommodates measurements up to 12" / 300 mm. For a workbench where measurements move between metric, decimal-inch and fractional-inch formats, this digital approach keeps those readings in one tool instead of requiring separate measuring tools for each unit.
In the box
The package includes the digital caliper and a battery. The caliper requires one LR44 battery.
Buyers commonly appreciate the readable measurements, unit options and usefulness for DIY tasks. Comments on overall build quality are mixed, so the clearest strengths to weigh are the documented measurement range, four measurement types and on-screen unit conversion.
Practical questions
What types of measurements can it take? It supports inside, outside, depth and step measurements, using the jaws and depth probe.
Can it show measurements in different formats? Yes. The display can convert between millimetres, inches and fractions, with resolutions of 0.01 mm, 0.0005" and 1/128".
What is the measurement range and accuracy? The range is 0-12" / 0-300 mm, and the stated accuracy is ±0.0015" / 0.04 mm.
Final verdict
This WONDERSUNM caliper suits a workbench that calls for more than one kind of dimensional check. Its stainless steel construction, large LCD, 0-12" / 0-300 mm range and metric, inch and fraction conversion bring the key measurements together in one tool for DIY projects and professional measuring tasks.
