4. Operation
4.10. Salinity (NaCl), TDS and Resistivity measurements
TC: linear, selectable between entre 0 to 5 % / ºC.
TRef: 25 ˚C / 20 ˚C / others
Factor (only for TDS measurements): 0.40 to 1.00
Measuring modes:
By stability.
In continuous.
By time.
Procedure for change measuring units:
4.10.1. Salinity measurements:
Salinity measurement with printer, See EC measurement with printer, page 12.
Important note:
It is not possible to measure salinity
with a TC=0 %/ ºC.
4.10.2. TDS measurements:
TDS measurement with printer, See EC measurement with printer, page 12.
