Description
Measurement is the first honest language a workshop speaks. A caliper that reads half a tenth of a millimetre in one place and something else in another is worse than no caliper at all, because it manufactures false confidence. The Zero Point is built the other way round: a hardened stainless-steel beam and jaws, a fixed glass grid read by a capacitive transducer, and a repeatable resolution of 0.01 mm (0.0005 in) on a 3 V CR2032 cell that runs beyond a year of daily use.
Four measurements, one instrument. Outside diameter, inside diameter, step and depth are all handled by the same tool, so a turned shaft, a bored hole, a shoulder and a blind recess do not each need a different gauge. Model 5110 is offered in 0-150 mm, 0-200 mm and 0-300 mm ranges, supplied in a protective case, with data output for recording readings to a PC and IP54 protection against workshop dust and splash.
The details that decide whether a caliper survives the bench. Hardened stainless resists the jaw wear that quietly ruins cheap instruments. A knurled locking screw holds a reading while you steady the part. A glass fixed grid does not drift with humidity the way a foil scale can, and a zero-set button means the reference is always yours to establish. CE and RoHS conformity, a one-year warranty, and one practical note we would rather state plainly than leave to discovery: units shipped from our warehouse arrive without the battery.
*A number you can trust is worth more than ten you cannot.*

Where It Belongs
This is the caliper that lives on the bench rather than in a drawer. Machinists use it for first-off checks on turned and milled parts. Brewers and fabricators measure wall thickness, tube bore and flange steps before welding. Woodworkers set blade and router depths to a tenth of a millimetre instead of guessing at a rule mark. Restorers, model engineers and electronics builders reach for the four-way jaws because one tool answers inside, outside, step and depth without a changeover. Buy the 0-150 mm range for general bench work, step up to 0-200 mm when larger assemblies come through, and choose 0-300 mm where frames, castings and long shafts are routine.
Frequently Asked Questions
Q: Does the caliper come with a battery?
A: Parcels shipped from our warehouse arrive without the battery. The instrument uses one 3 V CR2032 lithium cell, which is a standard item you can source locally.
Q: What do the 0-150, 0-200 and 0-300 options mean?
A: They are the maximum measuring ranges of the three models in the series, and they are the reason for the three price steps. Choose the smallest range that comfortably covers the largest part you measure, because shorter-range calipers read more accurately.
Q: How accurate is it?
A: The supplier specifies ±0.02 mm for the 0-150 mm model and ±0.03 mm for the 0-200 mm model, at a resolution of 0.01 mm (0.0005 in).
Q: Can it measure depth as well as diameter?
A: Yes. The jaws cover outside diameter, inside diameter and step measurement, and the extending rod covers depth.
Q: Is it waterproof?
A: It is rated IP54, which protects against dust and water splash. It is not intended for immersion, and it should be wiped dry before being returned to its case.
Q: Does it need calibration?
A: The hardened stainless construction and glass fixed grid are designed for stable, repeatable readings, and the unit can be zeroed at any point. For certified inspection work, have the caliper verified against your own reference standard.
Q: What is the data output for?
A: The output port lets readings be recorded to a PC for logging and inspection records, rather than written down by hand.
