My apologies for asking, but, are they the same? The K-1000 comes with R-0014, and the small comparator that reads 6.8-8.2(6.8, 7.2, 7.5, 7.8, 8.2). The K-2006 comes with R-0004, and the large comparator that reads 7.0-8.0(7.0, 7.2, 7.4, 7.6, 7.8, 8.0). I thought (don't know why) that the R-0004 was stabilized for higher chlorine.
