Product Information
Full details
The Hilka 150mm Vernier Caliper is an essential precision tool for engineers, woodworkers, and DIY enthusiasts who require highly accurate measurements for internal, external, depth, and step dimensions. Featuring a durable stainless steel construction and dual-scale graduations, this tool offers professional-grade reliability for projects up to 150mm (6 inches). While it is an incredibly precise mechanical instrument, users should be aware that it requires manual reading of the vernier scale, which may present a steeper learning curve compared to digital alternatives.

FAQs
What is the maximum measuring range of this caliper?
The Hilka vernier caliper has a maximum measuring capacity of 150mm, which is equivalent to 6 inches.
Does this tool require batteries?
No, this is a traditional mechanical vernier caliper and does not require batteries or electronic components.
Can this be used to measure the depth of a hole?
Yes, the tool features a depth rod that extends from the end of the beam, allowing you to measure the depth of holes or slots.
What is the accuracy level of this device?
The caliper provides an accuracy of +/- 0.02mm.
Is the stainless steel body rust-proof?
While the stainless steel construction is highly resistant to corrosion, it should be wiped clean and stored in its case to prevent any surface rust in humid environments.
Can I use this for measuring internal diameters?
Yes, the smaller stepped jaws at the top of the device are specifically designed for measuring internal dimensions of tubes and holes.
Troubleshooting
Measurements seem inconsistent.
Check the measuring surfaces for burrs or dirt. Ensure the beam is clean and the jaw slides smoothly without binding.
The jaw is loose even when the locking screw is tightened.
Verify that the locking thumb screw is fully engaged and not cross-threaded; do not overtighten, as this can damage the locking mechanism.
Difficulty reading the small vernier scale.
Ensure you are viewing the scale directly from above to avoid parallax errors. Using a small magnifying glass can assist in reading the precise line alignment.

Setup, Compatibility & Care
Before your first use, wipe the jaws and the beam with a clean, lint-free cloth to remove any protective oils or debris. To maintain accuracy, always ensure the measuring surfaces are perfectly clean before placing them against your workpiece. Avoid applying excessive force when tightening the locking thumb screw, as this can cause unnecessary wear on the screw threads. After use, retract the jaws slightly and place the caliper inside its padded case to prevent moisture buildup or accidental impacts that could misalign the jaws. Regularly inspect the instrument for any signs of surface rust; if found, apply a light coat of machine oil to protect the steel finish.
