OUTSIDE SPRING CALIPER 150MM RANGE 0-140MM

How to Use an Outside Spring Caliper:

1. Adjust the Legs: Place the caliper's legs around the outside of the object to be measured.
2. Fine-Tune the Measurement: Adjust the legs until they just make contact with the surface of the object, ensuring that the pressure is consistent but not excessive.
3. Lock the Position: Once the desired span is achieved, lock the caliper in place using the locking nut or screw.
4. Read or Transfer the Measurement: The span between the legs can be transferred to a ruler or compared to a standard to determine the object's dimension.

Key Features

1. Spring Mechanism:

   • Smooth Adjustment: The caliper features a strong spring mechanism that provides tension between the two legs. This spring allows for smooth and controlled adjustments when measuring.
   • Consistent Pressure: The spring ensures consistent pressure when measuring the outside of a workpiece, helping to improve measurement accuracy.

2. Curved Legs:

   • External Measurement: The two curved legs of the caliper are designed to measure the external dimensions of round objects, such as shafts, cylinders, and pipes. The legs are placed around the object, and the measurement is taken by adjusting the span.

3. Locking Nut or Screw:

   • Position Lock: Once the desired span is achieved, the caliper has a locking nut or screw that allows the user to lock the legs in place. This ensures that the measurement remains consistent and can be transferred or repeated easily.

4. Durable Construction:

   • Hardened Steel: Most outside spring calipers are made from hardened steel or other durable materials, making them resistant to wear and able to maintain precision over time.
   • Corrosion Resistant: The material is often treated to resist corrosion, making the caliper suitable for use in workshop environments where it may be exposed to oil, grease, or moisture.

5. Various Sizes:

   • Available in Different Ranges: Outside spring calipers come in various sizes, with different measuring ranges to accommodate small or large workpieces.
