For automatic Temperature Compensation, a temperature probe supplied by
istek
must be used. Temperature Compensation is automatically performed
while measuring.
Conductivity/TDS/Salinity/TEM P M eter
This model features to obtain a reliable data since its program is treated by setting in
detail about compensation factor(Temperature Compensation Coefficient, Cell
Constant, etc) for an accurate measurement.
This model displays Conductivity(
S, mS), TDS(mg/L), Salinity(ppt) and ATC(
C).
Conductivity
indicates conductivity of solution. (unit
S/cm and mS/cm)
TDS
indicates by converting the measured conductivity into concentration of the
total dissolved solid present solution from. (unit mg/L)
Salinity indicates by converting the measured conductivity into salinity of solution.
(unit ppt)

For automatic temperature compensation, a temperature probe supplied by
istek
must be used.
Temperature is automatically compensated on the base of Tref adjusted in
Setup. Tref indicates compensation temperature. Tref can be set with 25.0
℃
or 20.0
℃
for a basis.
815PDC
This meter features to measure pH, ISE, mV, ORP, DO, O2, Air, Conductivity, TDS,
Salinity and Temp, and automatically select a measuring mode by connection electrode.
If connecting pH electrode, the displays is shown as follows.
