 Details:
Unique dual optical path, dual detector turbidity measurement system
· LED (light emitting diode) light source than traditional tungsten lamp (Tungsten) longer lamp life (up to 100,000 hours), no need to replace the light source, the light source varies with temperature, better stability, higher accuracy, shorter warm-up time (about 1 second), good shock resistance
· 90 ° scattered light detection
Dual optical path, dual detector design, by measuring the beam and the reference beam to determine the ratio of the turbidity of the samples were colored and effective compensation
System designed to meet a number of turbidity testing standards
· Also comply with EPA 180.1 and ISO 7027 standard turbidity measurement
· Peers uniquely meets American Brewing Association (ASBS) and the European Brewing Association (EBC) turbidity test specification products
Excellent low turbidity measurement techniques
· 0 - 40 NTU low turbidity measurement complies with EPA GLI 2 Number Standard Methods
"Average" average calculation function, to ensure the lake with particulate matter and water turbidity measurement reliability of the results
