Suitable for HI2000, HI2020 tester. Applied to hydrocarbon, paint, solvent, seawater, strong acid and base, high conductivity sample, tris buffer solution and other sample measurement

When using new power, remove the top protective cover and check the whole power. If it is found that salt crystals are formed in the electrode and protective cover due to the evaporation of electrolyte in the electrodialysis film, it will not affect the normal use of electricity, indicating that the electrodialysis film is normal, and can be washed away with clean water. In transit, bubbles may form inside the bulb of the head, which can be removed by a gentle jolt of electricity, like a common mercury thermometer. If the electric glass induction film or dialysis film head is dry, can be soaked in HI70300 electric preservation solution for at least 1 hour, so as to keep the dry glass induction film and dialysis film moist; Frequent soaking is good for electricity.
