optekis Haze Control 4000 photometric converter

The Haze Control 4000, from optekis, is a powerful, microprocessor-based converter. Its modular design has been specifically engineered for high-precision haze (turbidity) measurements.

The menu-based software is easy to use and configure and available in German, English, French, Dutch, Spanish, Russian and Portuguese. The software includes adjustable signal damping, 16 linearisation tables and calculation capabilities. 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 photometric converter is designed to operate with the optek DTF16 (11°/90° scattered light sensor) and additionally with AF16 or AS16 visible (VIS) or near-infrared (NIR) based sensors. The graphic display can show absorbance, turbidity and concentration in real time and in any unit of measurement, such as EBC, FTU, ppm (DE), NTU, ASBC and Helms. These measurements may also be displayed as text, bar graphs or trend values. A factory zero point is implemented for the scattered light sensors.

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