1、采用气压方式输送油样，保持磨粒原始状态。
1. The oil sample is transported by air pressure to maintain the original state of abrasive particles.
2、输送油样的流量可在10-30ml/h内任意选择并设有快速挡。
2. The flow rate of transporting oil sample can be selected arbitrarily within 10-30 ml/h and has a fast stop.
3、铁谱片与磁铁表面的夾角可调，以满足不同粒度磨粒油样的选用。
3. The angle between the ferrographic plate and the surface of the magnet can be adjusted to meet the selection of abrasive oil samples with different particle sizes.
4、双色显微镜具有透射、反射及偏振光照明，并配有多种滤色片。采用平场消色差物镜和平场目镜使光学系统成象清晰，观察舒适。亦可进行显微攝影。
4. The dual-color microscope has transmission, reflection and polarization illumination, and is equipped with a variety of color filters. Flat field achromatic objective and flat field eyepiece are used to make the optical system image clear and observe comfortably. Microscopic photography is also available.
