Proster Digital Vernier Caliper, 200mm/8-inch with 32 Feeler Gauges

For checking a component’s dimensions at the workbench or measuring a gap during an automotive task, the Proster Digital Vernier Caliper brings several measuring options together in one set. It covers internal, external, depth and step measurements, with a separate feeler gauge for checking clearances.

The caliper measures from 0 to 200mm or 0 to 8 inches. Its large LCD presents readings clearly, and you can switch between inch, metric and fraction modes to work in the format that suits the job.

Need to measure both a part’s diameter and a narrow gap? The caliper and 32-blade gauge give you tools for both tasks in the same set.

Highlights

The caliper has hardened stainless steel construction, with measuring jaws for internal and external dimensions and a depth blade for reaching into recesses. It can also measure step dimensions, making it useful for comparing a component’s different surfaces without changing to a separate measuring tool. The stated accuracy is 0.001 inch/0.02mm, with a resolution of 0.0005 inch, 1/128 inch or 0.01mm.

The LCD is designed for easy reading, while the conversion chart on the back provides a handy reference. Choose between inches, metric measurements and fractions to keep readings in a familiar format, whether you are working with a drawing or checking an existing part.

The set also includes 32 feeler gauge blades made from hardened tempered steel. Their measurement range is 0.0015 inch/0.04mm to 0.035 inch/0.88mm, giving you a way to check clearances alongside the caliper’s dimensional measurements. A lubricating oil coating helps protect the blades against pitting and corrosion.

How to use it

Select the display format that suits your task, then use the caliper jaws for outside or inside measurements. For depth measurements, use the blade, the caliper can also check step dimensions. The feeler gauge is suited to assessing a gap or clearance: choose a blade within its stated range and use it to check the space between surfaces.

For example, when inspecting a part, you can measure its external width with the caliper and then use a feeler blade to assess a nearby clearance. The included case provides a place to store the measuring tools together between jobs. The set contains the digital caliper, feeler gauge, case, battery, extra LR44 battery, mini screwdriver and user manual.

Who it’s for

This set suits workshop users, DIYers and people carrying out automotive or general industrial measuring tasks who want to check more than one type of dimension. The combination of internal, external, depth and step measurements is useful when a component has several surfaces to assess, the feeler gauge adds a separate way to check narrow gaps.

If you are choosing between a caliper on its own and a measuring set with clearance gauges, this Proster option brings both functions together. Its inch, metric and fraction displays are practical when measurements need to be read in different formats. It suits you if you want one stored set for checking part dimensions and clearances across a range of jobs.

Final verdict

With a 0–200mm/0–8-inch range, a clear LCD and three measurement formats, this digital caliper is set up for versatile dimensional checks. The 32-blade feeler gauge extends the set to clearance measuring, making it a useful fit for workbenches and automotive tasks where both kinds of measurement matter.
