Contact lens oxygen permeability measuring instrument

製品紹介：

Contact lens oxygen permeability measuring instrument （polarography） is designed for soft and hard contact lenses （contact lenses） or similar materials manufacturers and laboratories designed for oxygen permeability polarography test equipment, suitable for hydrogel, silicon hydrogel, high oxygen permeability materials and other lenses. Generally, a complete polarographic measurement scheme should include at least a host, an electrode assembly frame, an electrode, a central thickness gauge and a constant temperature and humidity box.
