Online PH meter
Online PH meter is a new generation of microcomputer-based high-grade instruments with English display, English menu operation, full intelligence, multi-function, high measurement performance, strong environmental adaptability, etc., can accurately measure the pH value and temperature of the solution. It can be widely used for continuous monitoring of pH in solutions such as thermal power, chemical fertilizer, metallurgy, environmental protection, pharmaceutical, biochemical, food and tap water.
one set of pH secondary meter, one electrode, one pack of pH (4, 7, 9) standard buffer.
1. English LCD display, English menu operation, English notes
2. Micro computerization: High-performance CPU chip, high-precision AD conversion technology and SMT chip technology are used to complete multi-parameter measurement, temperature compensation and meter self-test, with high precision and good repeatability.
3. High reliability: single board structure, touch buttons, no switch knobs and potentiometers.
4. Waterproof and dustproof design: IP65 protection, suitable for outdoor use.
