A guide to UNIOR measuring tools: digital and vernier calipers accurate to 0.02 mm, micrometers, tape measures, standard and magnetic spirit levels, squares and feeler gauges.
A wrong measurement means a ruined part. UNIOR has measuring tools for the workshop and the site.
Precision measuring
| Tool | Accuracy | Use |
|---|---|---|
| Digital caliper | 0.02 mm | Direct reading on the display, inside and outside diameter and depth |
| Vernier caliper | 0.02 mm | No battery, suitable for workshops |
| Outside micrometer | More accurate than a caliper | Shafts, bearings and lathe parts |
Caliper or micrometer? A caliper is fast and measures several ways (inside, outside and depth). A micrometer only measures outside dimensions but is more accurate, so you need it when fractions of a millimetre matter.
Feeler gauges
- Feeler gauge 13 and 20 blades: for measuring the clearance between parts, such as engine valves and spark plug gaps.
- Metric and inch thread pitch gauge: to find the thread pitch of a bolt.
Tape measures
- Tape measure 2-10 m and 2-8 m.
- Folding rule 2 m: for carpenters.
- Long tape 50 m: for measuring land and long distances.
Spirit levels
| Level | Length |
|---|---|
| Spirit level | 120-2000 mm |
| Magnetic spirit level | 120-1000 mm |
| Industrial level | 1500 mm |
| Long industrial level | 2000-4000 mm |
A magnetic level sticks to steel, pipes and frames, so your hands stay free while you adjust.
Marking and squares
- Industrial squares: 150-300 mm, 150-300 mm, and 300-500 mm.
- Industrial aluminium straight edge 500-1000 mm.
- Scriber 150 mm and plumb bob 170 g.
Tips
- Zero the digital caliper before every measurement, and clean the jaws.
- Check the level: place it on a surface, then turn it 180 degrees. If the bubble is in the same place, the level is accurate.
Pros ✅
- 0.02 mm accuracy with the caliper
- Levels up to 4 m for sites
Cons ❌
- Precision measuring tools are affected by knocks and drops, so store them in their case
