Enables measurements with minimal error

Measurements are affected less by ambient temperature and sample temperature, enabling accurate measurements with less error.

Highly responsive temperature sensor

Helps to minimize fluctuations in measurement values due to delayed temperature compensation in the event of sudden changes in water temperature.

We provide equipment and sensor calibration services

Temperature sensor offset calibration is offered as well as transmitter and sensor combination calibration services. *Option

2-channel specification

Allowing measurement at 2 points, and capable of displaying salt removal rate.
