High Precision Universal Metroscope
The base is high quality cast iron and is aging for long time by nature so as to have good stability.
The measuring main axis adopts optimum square design to assure the stability of moving performance.
It has powerful optional accessories to satisfy different measuring requirements
The grating illuminating system adopts infrared illuminating device with low voltage, small current and long life as light sources.
The instrument adopt high precision measuring system, which conforms to the Abbe principle and has high measuring precision.
JD36H imported grating system and subdivision card have high precision and reliable stability.
JD36H 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 find reversal point.
