Here is a quick guide for measuring tool selection.
For the purposes of simplicity, we will not include the range of measurement. Resolution refers to how fine the smallest unit of measurement is displayed on the product.
Length Measurement
This occurs when you are measuring a work piece horizontally or vertically.
| Resolution | Product |
| 1mm | Circometer (Pipe Measuring) , Measuring Tape , Laser Distance Tape |
| 0.5mm | Rulers |
| 0.01mm | Digital Caliper |
| 0.001mm | Digital Micrometer , Vernier Caliper (Special request) |
Depth Measurement
This is used to measure the depth of parts
| Resolution | Product |
| 0.05mm | Depth Gauge |
| 0.01mm | Thread Depth Gauge , Keyway Caliper |
| 0.001mm | Digital Dial Indicator , Depth Micrometer (Special Request) |
Tolerance measurement
This is used to measure the depth of parts or gaps between parts.
| Resolution | Product |
| 0.1mm | Feeler Gauges , Jet Gauge |
| 0.01mm | Dial Indicator , Digital Dial Indicator , Thickness Gauges |
| 0.001mm | Digital Dial Indicator |
Flatness tolerance can also be measured in conjunction with straight edges.
Internal Measurement
For measuring bores, and bore length tolerances as well as other internal measurements.
| Resolution | Product |
| 0.01mm | Bore Gauge , Digital Vernier Caliper (Grooves) (Request), Digital Caliper |
| 0.001mm |
Digital Dial Indicator with Bore Gauge (Request) , Telescopic Gauge |
Coating Thickness Measurement
This occurs when you are the thickness of a coating on an object. This can be powder coated materials, or painted materials. Also can apply to measuring the thickness of bare workpiece.
| Resolution | Product |
| 0.01mm | Ultrasonic Thickness Gauge |
| 0.001mm (1um) | Coating Thickness Gauge (good for powder coated materials) |
Thickness Measurement
This occurs when you are the thickness of a workpiece.
| Resolution | Product |
| 0.01mm | Quicktest Gauge |
| 0.01mm | Ultrasonic Thickness Gauge |
Angle Measurement
This is used to measure angles on 2 workpieces
| Resolution | Product |
| 0.1 degree | Protractor |
| 0.01 degree | Digital Protractor |
Rotation Speed Measurement
This is used to measure the speed and revolutions of mechanical rotating parts
| Resolution | Product |
| rotation / minute | Digital Tachometer |
Flatness Measurement (2 Axis)
This is used to make sure the plane that the machine is working on is stable and balanced. Measures both X and Y axis. These products can also measure inclination (or angle on a single piece)
| Resolution | Product |
| 0.01 degree | DWL 2000XY , DWL 3000XY |
| 0.001 degree | DWL 1500XY , DWL 3500XY , DWL 8500XY |
For this range the accuracy depends on the model and is often measured in mm/m. A product with 0.2mm/m is usually requested. We have products up to 0.005mm/m or about 5 arc second.
Surface Topography
This measures how to surface looks like and can cover multiple aspects.
| Measuring | Product |
| Roughness | Roughness Tester |
| Mapping of surfaces | DWL 8500XY (produce map on screen) |
