SJ2210 Small Angle Calibration Instrument

SJ2210 Small Angle Calibration Instrument is a high-precision small angle measuring instrument used to calibrate and verify the angle indication errors of frame level, bar level, composite level, electronic level, autocollimator and other instruments.

This instrument uses a high-precision imported grating as the main component and a high-precision length meter as the measurement reference, replacing the original measurement method that uses gauge blocks as the measurement reference, reducing external factors that affect the measurement results. It is easy and fast to operate, and users only need to input the relevant information of the tested instrument and press "start calibration". The instrument will automatically generate a standard angle according to the regulations, perform simple operations on the tested level, and then input the reading error or error data of the tested meter on the touch screen interface. The instrument will automatically calculate the calibration data and judge the calibration result according to the regulations. The verification process is simple and the verification efficiency is significantly improved.
