Devices of SPECTRO-3 series are designed to detect “true-color” (human color reception). Sensors can be used in AC or DC modes, with internal or external light source.

The sensors of the COAST Series (COlor And STructure) are hybrid sensors that comprises two sensors that only are synchronized by the LED ring light but otherwise operate independently of each other. Both sensors can be connected to a PLC or to a PC.

COMET Cloud is an Internet data storage designed for recording measured values from selected COMET measuring instruments. The data is accessible after the user's connection to the Internet and is displayed in a web browser in the form of a table or graph. Users can be notified by e-mail of all alarm conditions reported by the device. After purchasing a device that supports connection to the COMET Cloud, you can register the device in the COMET Cloud. Each user has access only to their account, which is password protected. If you run a large number of devices in the COMET Cloud, you can clearly organize them into groups and assign new users to them, who can have an overview of the group of devices. Different rights for data display and administration can be set for individual users.

Notification app for Android or iOS
