Customer reviews

Sarah Williams · Research Scientist
The Pocket Pen-Type Roundness Tester PenRound 100 is surprisingly capable for its size. I use it daily for quick checks on small precision components, and it's become indispensable for my research work. The measurement accuracy is impressive for a handheld device, and the touchscreen interface is very user-friendly. It's perfect for situations where bringing parts to a lab isn't practical.

Product Description

Product features:

This pen-type roundness tester adopts a micro inductive sensor, which is suitable for detecting small workpieces with a diameter of 5-50mm, meeting the detection needs of micro components. It has an ultra-lightweight design with a total weight of only 150g, which can be carried around, greatly improving the convenience of on-site detection. It supports one-key operation, no professional training is required, and ordinary operators can master the use method quickly. The 0.96-inch OLED screen displays measurement data in real time, and supports Bluetooth synchronization to the mobile phone APP for data analysis, which is convenient for sorting and recording detection results. It is powered by AAA batteries with a battery life of up to 30 hours, solving the power supply problem of temporary outdoor detection.
