Grade Tester

Automatic grade testing of high precision

Overview

OKK's Grade Tester is developed to solve issues such as a variation in test results, caused by manually turning a handle with individual differences in operation speed or strength.
Only need to make settings of test conditions to perform the loading and testing.
Contributes to simplified operation and improved quality control.

Features

Grade testing based on JIS Standards

With this automatic testing device based on JISR6240 of Japan Industrial Standards, you can make various settings such as the measurement bit rotation speed, the load, or other items, which makes it outstandingly high- precision than other devices in the market.

The automatic operation will conduct the testing based on standards or conditions without individual variation.
