Catalog excerpts

CODA-500-1

*1 Channel-based compatibility with the former CODA-200 series products is available (standard). *2 Within ±5% F.S. in case options (2 points measurements, 2 ranges, line cleaning by reagent etc) are added, and when using cleaning function of CODA-500C. *3 If tap water is used, first perform flushing for about 30 minutes and then send tap water to the CODA-500. For the version using a tank, use pure water of 10 mS/m (=1.0 • S/cm) maximum.
