Purpose: Dedicated for transformersCircumference rulerIt is used for on-site measurement of the average diameter and circumference of transformers.

Structure: It is mainly composed of a steel strip with a scale, with one side showing the circumference value and the other side showing the diameter value. Both ends have scales with a division value of 1mm.

Advantages: Two readings can be measured at once, and the diameter value corresponds to its circumference value, changing the previous practice of converting diameter to circumference and measuring circumference to diameter, greatly improving measurement efficiency. Convenient to carry and store.

usage method:

Outer diameter measurement:Transformer circumference rulerBy wrapping around the workpiece and applying a pulling force of _ with both hands, the average diameter and circumference of the tested object can be read. After the measurement is completed, roll up the ruler.
