main features

Double row digital tube: displays conductivity and temperature values separately. Microcomputerization: Using high-performance CPU chips, high-precision AD conversion technology, and SMT surface mount technology, it completes multi parameter measurement, temperature compensation, and automatic range conversion with high accuracy and good repeatability. High reliability: Single board structure, touch sensitive buttons, no switch knob or potentiometer. Automatic conversion of measurement frequency: avoids electrode polarization and improves measurement accuracy. 25 ℃ conversion: Temperature compensation manual input (DDS-11A without temperature compensation). Waterproof and anti-corrosion design. Network function: RS232 bidirectional communication, compatible with printer or TLab1.0 communication and data processing software. Industrial control watchdog: ensures that the instrument does not crash and can measure high-purity water: DDS-11D with titanium alloy electrode and sealed measuring cell with electrode constant of 0.01cm-1. Automatically prompt the measurement endpoint.

TLab1.0 software displays instrument parameters, measured values, and curves

The difference among the three is the range of electrode constants.

DDS-11A does not have temperature compensation.

DDS-11A single row digital display.
