Question 1

How does the SATA GL91503 Vernier Caliper work and what can I measure with it?

Accepted Answer

The GL91503 is a precision vernier caliper made from stainless steel. It uses a main scale and a sliding vernier scale to give measurements with a resolution of 0.02 mm. It can measure external dimensions (outer diameter), internal dimensions (inner hole/diameter), and depth.

Question 2

What is the measurement range and the precision of this caliper?

Accepted Answer

It offers a 0–300 mm measuring range and reads down to 0.02 mm, with dual metric and imperial units for convenience.

Question 3

What materials and design features does the GL91503 have?

Accepted Answer

It is crafted from stainless steel for durability and rust resistance. It includes smooth sliding action, a built-in locking screw to secure measurements, clear large markings, and an ergonomic grip for comfortable use. It also ships in a protective ABS plastic box.

Question 4

How do I measure outer diameter, inner diameter, and depth with this caliper?

Accepted Answer

For outer diameter, use the external jaws on the caliper. For inner diameter, use the internal jaws. For depth measurement, extend the depth rod from the end of the caliper and place it into the hole or cavity you’re measuring, then read the scale.

Question 5

How do I switch between metric and imperial units on the GL91503?

Accepted Answer

This caliper supports both metric (mm) and imperial (in) readings. Read the scales printed on the tool in the units you need; there isn’t a separate button—simply use the appropriate scale on the main body and vernier for the measurement.

Question 6

How do I lock a measurement to prevent it from changing?

Accepted Answer

Use the built-in locking screw to fix the jaws in place after you obtain a measurement. This helps prevent any drift while you record the size.

Question 7

What are common use cases for this caliper?

Accepted Answer

It’s ideal for mechanical and engineering tasks: checking parts during assembly, quality control in manufacturing, woodworking fittings, automotive components, and hobbyist projects where precise dimensioning is needed.

Question 8

How should I care for and maintain the caliper to extend its life?

Accepted Answer

Wipe the scales after use to remove dust and residues, lightly oil the sliding surfaces if needed, avoid dropping or banging it, and store it in the included ABS box to prevent corrosion and damage.

Question 9

How does this caliper compare to other similar calipers on Fepy?

Accepted Answer

Compared to longer- or shorter-range variants, the GL91503 offers a solid 0–300 mm range with 0.02 mm resolution in a stainless steel body. For different ranges, you can check other Fepy options such as: GL91501 Vernier Caliper 0-150 mm (https://fepy.com/product/sata-gl91501-vernier-caliper-0-150mm) and GL91504 Vernier Caliper 0-400 mm (https://fepy.com/product/sata-gl91504-vernier-caliper-0-400mm). A mid-range option is GL91502 Vernier Caliper 0-200 mm (https://fepy.com/product/sata-gl91502-vernier-caliper-0-200mm).

Question 10

What are some practical use cases for this caliper in real-world projects?

Accepted Answer

Use it when assembling mechanical parts, verifying component tolerances, checking hydraulic or pneumatic fittings, inspecting instrument housings, or any task requiring precise dimension checks, from DIY projects to professional manufacturing.

Question 11

Are there any safety or handling guidelines I should follow when using this caliper?

Accepted Answer

Yes. Handle it gently to avoid bending the jaws, keep the scale clean to maintain reading accuracy, and use the locking screw to prevent slips during measurement. Don’t rely on a caliper for critical safety-related measurements without proper calibration, and store it in its case when not in use.

Question 12

Is this caliper good value compared to other options on Fepy, and what should I consider when deciding to buy?

Accepted Answer

If you need a robust, stainless-steel vernier caliper with a 0–300 mm range and 0.02 mm resolution, the GL91503 offers reliable performance and a protective case at a competitive price. Compare ranges (e.g., 0–150 mm or 0–400 mm variants) and consider whether you’ll frequently work with larger parts or need finer resolution.
