HK-368U integrated acid/alkali concentration meter
Introduction: HK-368U integrated acid/alkali concentration meter uses a new detection technology, no zero drift, high sensitivity, good stability, waterproof and anticorrosive, simple installation and use, mainly used for ion exchange monitoring in the process of preparing high-purity water by ion exchange The concentration of the medium regenerated liquid is a necessary instrument for the production of high-purity water by the ion exchange method. It can be widely used in the electric power, chemical, metallurgical, food, pharmaceutical and other industries to increase the concentration of various HCl, NaCl, NaOH, H2SO4 and other strong electrolytes. Accurate and continuous monitoring. Features: 1. The non-contact detection method fundamentally eliminates the corrosion, pollution and polarization effects of strong corrosive media on the electrode; 2. Using variable frequency excitation power supply and resonance circuit and its unique signal sampling method instead of single frequency excitation method, the output voltage of the detection transformer is increased by hundreds of times, and the flow-through sensor does not need to be zeroed, which greatly improves the accuracy and sensitivity of the instrument to stabilize Sex; 3. The flow-through sensor adopts low-temperature magnetic structure and ferromagnetic shielding. The ferromagnetic material near the installation location will not affect the zero point of the scoring table, and there is no zero point drift in long-term use; 4. Using a microcontroller (MCU) and a dedicated interface integrated circuit, the output voltage of the detection transformer and the output current of the temperature sensor are fully digitally sampled, calculated and displayed. 5. It can realize high-precision temperature compensation, local display and remote output of concentration values; 6. It adopts imported all-plastic sealed shell, which can be used for a long time in extremely harsh environments such as humidity, dust and corrosiveness.
