The Optek Control 4000 Photometric Converters advanced modular design enables precision process monitoring and control. The flexible C4000 is designed for Optek ultraviolet (UV), visible (VIS), near-infrared (NIR) absorption-based and scattered-light based sensors.

The menu-based software is easy to use and configure and is available in German, English, French, Dutch, Spanish, Russian and Portuguese. The high contrast white display is easy to read and remains configurable. The graphic display can show absorbance, transmittance, and concentration in real time and in any unit of measure such as CU, ppm, EBC, FTU, and g/l. These measurements may also be displayed as text, bar graphs or trend values.

The C4000 software includes adjustable signal damping, 16 linearization tables, and advanced calculation capabilities. As an additional feature for scattered light sensors a factory zero point is implemented.

A secondary zero for additional offset as well as a slope adjustment is included. This manual adjustment can be used to compensate for long-term process related disturbances.

An integrated data logger captures vital process information for quality assurance and plant control records. This data is easily transferred to a PC via an RS232 port.

The C4000 series converters provide multiple analog and relay outputs for direct measurement and control. An optional remote card allows process functions such as product switching, ranging, remote zeroing, and hold to be triggered remotely from other process control instruments or systems. Some models are capable of multiplexing up to four Optek inline sensors and/or probes.
