Online industrial pH meter

ORP detectorPrecautions for use:

1. The limited service life of the PH electrode is one year. Within one year after the electrode leaves the factory, regardless of whether it is used or not, the electrode performance will be affected and should be replaced in a timely manner;

2. When the electrode leaves the factory, there is a protective cap on the electrode head, which contains a special protective solution to maintain the moisture of the sensitive film. The protective cap should be removed before use;

When installing electrodes, do not collide with the composite electrode ball film to avoid damage;

4. The electrode cannot directly contact oily substances. If there is dirt on the glass ball, it can be cleaned with 0.1N hydrochloric acid and then immersed in KCL solution for activation. It cannot be touched by hand;

5. The electrode cable connector must be kept clean and free from moisture or water ingress; It is also not allowed to use other wires to extend the length.

6. The pH meter must be regularly calibrated after a period of use or when replacing the pH electrode, with a calibration cycle of generally 3 months.

7. The scroll symbol "⊕" is displayed in the lower right corner of the instrument, indicating that the instrument CPU is in working state.

ORP detectorUsage scenario:

Widely applicable for online measurement of pH value in high-purity water and water production equipment in industries such as electronics, chemical, environmental protection, pharmaceuticals, and food. Equipped with pipeline connected composite electrodes, it has the advantages of easy use, accurate readings, and stable numerical values.
