main features

Chinese LCD display, Chinese menu style, Chinese note taking. Microcomputerization: Using high-performance CPU chips, high-precision AD conversion technology, and SMT surface mount technology, it completes multi parameter measurement, temperature compensation, automatic range conversion, instrument self-test, 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. Phase sensitive detection design: eliminate the influence of wires on measurement. Electromagnetic compatibility (EMC/RFI) design: Designed and manufactured according to European standard EN50081/50082. There are two calibration methods: automatic calibration with 2.00%, 4.00%, 6.00%, and 8.00% options, and manual input of electrode coefficients. Waterproof and anti-corrosion design. Network function: RS232 bidirectional communication, compatible with printer or TLab1.0 communication and data processing software. Historical data: Store 3000 pieces of data. Notepad function: Record 200 pieces of information. Built in real-time clock: provides time benchmarks for various functions, etc. Industrial control watchdog: ensures that the instrument does not crash. Password management: Both parameter settings and maintenance are password protected.
