The JLHM-207 coulometric trace water measuring instrument is based on the single-chip microcomputer control and successfully integrates our understanding of the physical and chemical phenomena related to the measurement process. It has fast analysis speed, high precision, direct display of measurement results, and multiple analysis methods. It allows you to set freely, print records, and solidify the operation time. It is an effective, fully automatic precision analysis instrument.
Adopt 7-inch TFT true color LCD touch screen, Chinese menu, pictures and texts;
Using 32-bit microprocessor as the main control core, a new generation of intelligent operating system;
Using constant current polarization detection technology, good stability, high precision, fast measurement speed;
The dual-channel isolated power supply separates the electrolytic electrode from the measuring electrode, and the instrument can automatically remove various interferences, greatly improving the precision of the test results;
With automatic data query function, it is convenient to find test records and statistical data, and the results can be printed at any time;
The sample number and the total amount of the sample can be set, and the report is automatically calculated and generated, and the result can be printed at any time;
It has the automatic detection function of measuring electrode open circuit fault, short circuit fault, electrolyte over iodine, water and other instrument faults.
