Application
High quality casting, after long term natural aging treatment, are selected for the base, with fine stability.
Optimized square design is adopted for the spindle to assure the stability of it's kinetic property under measurement.
Accessories with powerful and multiple functions may be selected to satisfy different requirement in measurement.
The infrared light-emitting component with low voltage, small current, small volume and long life are adopted as the light source in the grating lighting system.
The high precision measuring system is adopted for this instrument, which would be in conformity with the Abel Principle and with high precision in measurement.
The imported grating system has high precision and reliable stability; The main measuring axis adopts optimum square design so as to ensure the moving stability; The function is powerful by connecting to computer, which can rectify the measuring error caused by indicating value and temperature variation. And it has the function for automatically fin reversal point;
