Oxygen permeability of contact lenses is an important indicator of contact lenses. The oxygen permeability of contact lenses directly affects the comfort of the wearer when wearing the lenses. The contact lens oxygen permeability tester (TO-C2 isobaric oxygen permeability meter) is suitable for the oxygen permeability measurement of contact lenses. Product details are as follows: TOY-C2 Isobaric Film/Container Oxygen Permeator Contact lens oxygen permeability tester features Oxygen permeability Dk/t and oxygen permeability coefficient Dk can be measured Microcomputer control, LCD display test parameters, test results The host has test parameter settings; process data real-time printing function With test temperature and test gas humidity control function At the same time, it has the function of plastic diaphragm and finished container testing. The device is equipped with RS232 interface and is equipped with professional computer software. Unaffected by power failure, the test process can be automatically resumed after power-on Network transmission interface supports LAN data centralized management and Internet information transmission Quick calibration of the instrument with standard membranes Contact lens oxygen permeability tester test principle Oxygen flows on one side of the sample, high-purity nitrogen flows on the other side of the sample, oxygen molecules diffuse through the sample to the other side of the nitrogen, are carried by the flowing nitrogen to the oxygen analysis sensor, and are measured by the sensor The oxygen concentration is analyzed to calculate the oxygen permeability of the sample and the like. When the finished container is tested, nitrogen flows through the container, and air or high purity oxygen surrounds the outside of the container.
