The KOBOLD turbidity meter LAT-N1 senses very weak to average turbidity values according to Formazin standard (FTU); EBC´s may also be used. The device operates according to DIN 38404/ISO 7027 with the 4-beam pulsating light technique, whereby soiling of optics as well as the effects of light from external sources and drift in electronic components are reliably compensated. The evaluating electronics and the fitting combine to make a compact robust instrument that can be easily installed. The process connection has been designed according to the hygienic standard for pipe screwings (DIN 11864). Thus the most stringent hygiene requirements are satisfied. Welded hexagon nipples and dairy connections according to DIN 11851 are also available. The device measuring range can be changed manually or with a digital signal. Thus the measurement accuracy across the entire turbidity range of 0.01 - 5 FTU to 0.01-1000 FTU is very high. The 4 - 20 mA output signal allows different evaluating devices such as digital indicators, limit value controllers or a PLC to be connected.
