main features

Double row digital display simultaneously shows μ g/L/pNa/mV and temperature. Microcomputerization: Using high-performance CPU chips, high-precision AD conversion technology, and SMT surface mount technology, it completes multi parameter measurement, temperature compensation, high accuracy, and good repeatability. High reliability: Single board structure, touch sensitive buttons, no switch knob. Input impedance>10¹²Ω. High sensitivity: 0.2ppb (8pNa) can be detected in static water samples. Long stable time with a very stable reading. 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.
