If salt crystals are formed in the electrode tip and protective cover due to the evaporation of electrolyte inside the electrode through the dialysis membrane, it does not affect the normal use of the electrode, indicating that the electrode dialysis membrane is normal. Rinse it off with clean water. During transportation, bubbles may form inside the glass ball of the electrode head. In this case, gently shake the electrode like a common mercury thermometer to remove the bubbles. If the electrode glass induction membrane or dialysis membrane head is relatively dry, the electrode can be soaked in HI70300 electrode preservation solution for at least 1 hour to keep the dry glass induction membrane and dialysis membrane moist; Frequent soaking is beneficial for electrodes. Reminder: Do not use distilled water or deionized water to store or soak electrodes, as this will cause electrode sensor failure

HI7051

Hana's unique soil preparation solution is an electrolyte solution used to measure soil pH. The acidity pH or conductivity of soil is usually measured as a slurry or electrolyte slurry, where a fixed ratio of soil: solvent (solvent is water or electrolyte solution) is selected. The commonly used ratios for acidity pH or conductivity are 1:1, 1:2, or 1:5, where more solvents are used when the soil to be analyzed contains a large amount of organic matter or clay. It is usually preferred to use electrolyte solutions because they are less affected by soil electrolyte concentration and provide more consistent measurements for soils where salt content may fluctuate due to seasonal conditions or crop residues. Using HI7051 solution before measurement can more accurately read the acidity pH or conductivity values of soil samples. Made with high-purity chemical reagents and high-quality deionized water, carefully prepared using rigorously certified measuring tools and containers in a constant temperature and humidity environment that meets requirements, and traceable to NIST standard reference materials (SRM); The soil preparation solution is formulated with a special formula and sealed with a unique tamper proof setting to ensure the quality and freshness of the acidic soil preparation solution.

HI721319

HI721319 customized soil pre-treatment loosening drill rod makes soil testing simple. When starting the measurement, first use a customized soil pre-treatment loose drill rod to drill the soil to a depth of about 20 centimeters or deeper to expose the pure soil and obtain a more accurate sample. Characteristics: Ideal partner for soil measurement; The conical tip is easy to penetrate the topsoil; High quality plastic material is easy to use and clean. Suitable for soil measuring instruments such as HI99121 and HI98168
