Control 4000

The Control 4000 is a microprocessor-based, photometric converter with an advanced modular design that enables precision process monitoring and control. This flexible converter is designed for use with the manufacturer’s ultraviolet (UV), visible (VIS), near-infrared (NIR) absorption-based and scattered-light-based sensors. The new high-contrast graphic display shows 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. An additional feature for scattered light sensors is a factory zero point; a secondary zero for additional offset and slope adjustment has also been added to the design. 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, which are easily transferred to a PC.
