The vernier caliper measures length by aligning the scales of the main scale and the vernier scale, and is used to measure the internal and external diameters and depths of objects. In the laboratory, it is used to inspect material dimensions and ensure machining accuracy.
Selection
When selecting a vernier caliper, consider the measurement range, accuracy grade, and material. Stainless steel material is durable, and digital displays facilitate easy reading. Determine the division value based on measurement needs and check the clarity of the scale.
Measurement range +/- 180 degrees, accuracy of 0.05 degrees, using sodium Illuminant and vernier reading, easy to operate, can quickly determine the optical rotation and calculate the material purity, concentration and specific rotation.
