HI123 high-precision measuring instrument Hana * has newly launched a large screen high-precision water quality comprehensive measuring instrument that can simultaneously measure acidity, ion concentration, and temperature. It can monitor electrode response and electrode usage status in real time (only dedicated electrodes with electrode serial number P have this function), identify erroneous or contaminated buffer solutions, whether the measured value is within the calibration range, and automatically issue warnings. This instrument has 7 built-in standard calibration values, allowing users to choose 1-5 calibration points according to their actual requirements, making the measurement more accurate.
