Φ8mm Extended Measuring Aperture
(accessory for NH310 colorimeter)
Extended measuring aperture can be used to not only measure the large surface, but also to perform color measurement on small surface, circular surface and concave surface.
In the past, whether the colorimeter is the hand-held, portable or desktop, imported or domestic,the colorimeter can only measure a large area; but to the concave parts, it is powerless. Therefore, I added a 3nh Φ8mm extended measuring aperture to solve the problem.
