Temperature
compensation

Temperature element

Platinum resistor: 1 kΩ (0℃)

Temperature compensation

• Temperature characteristic of NaCl (reference temperature: 5℃ to 95 ℃)

• Arbitrary temperature coefficient input (reference temperature: 5℃ to 95 ℃; temperature coefficient: ±3％/℃)

• No temperature compensation
  One of the three ways of compensation is selectable.
  (In the de-ionized water area, the temperature compensation for pure water is automatically performed in both NaCl and arbitrary temperature coefficient compensation settings.)

Temperature compensation
range

0 ℃ to 100 ℃(However, the compensation calculation is extended lower than 0℃ or higher than 100℃.)

Temperature calibration

1 point calibration comparing to reference thermometer

Calibration

Conductivity

Based on parameter input of coefficient for the sensor cell constant.

TDS conversion

Conversion by user-defined coefficient value (TDS calculation is 0.30 to 1.00 times of sample conductivity by μS/cm.)

Self-check
