*CS51LC conductivity sensor (0. 1 constant) required for these ranges.
Conductivity/TDS
AQUASWITCH
II
Controllers require a sensor with a cell constant of 1.0. The Model CS51 is the
most commonly selected sensor due to its ease of use and low cost.
Resistivity
AQUASWITCH
II
Controllers require a sensor with a cell constant of 0.05. The Model CS10 is the most
common selected due to its ease of use and low cost.
NOTE: UNLESS ppm/NaCl is specified with order, TDS/ppm type conductivity instruments will be calibrated to the
Myron L "442™" Natural Water standard. For NaCl ppm/ppt add the letter "N" after the number, i.e. -114N.
