Vacuum Coating Thickness Meter

As an Authorized dealer we are engaged in providing the broad assortment of "Coating Thickness" instruments for various applications.

The transmittance of the material (optical density) and the thickness of the coating to a certain proportion of the relationship. This is achieved by monitoring the optical transmittance of the material (optical density) to achieve the purpose of monitoring the uniformity of the material, the thickness of the coating. As long as it is light can be transmitted the material, you can monitor the transmission rate to monitor the quality of products. Such as winding vacuum coating, glass coating, glass production line and so on.

Vacuum coating online thickness monitor provides dual RS485communication interface, the standard MODBUS communication protocol, convenient for communications with PLC, human-machine interface and computer. Coatingmachine can directly communicate with instrument to get optical density data torealize the automatic control (closed-loop control).
