GENERAL DESCRIPTION pH is a pH meter specially designed to meet the needs of growers in greenhouses and hydroponic applications. It is equipped with a large LC display which make easy to read measurements from distance at any time. The housing has been completely sealed against vapors and humidity. The HI 1286 gel-filled pH electrode is interchangeable and the BNC connector is protected behind a waterproof sheath. The meter is also supplied with HI 1283 stainless steel probe to prevent potential grounding problems and thus ensuring longer life for your electrode, which has been designed for use in fertilizer solutions with high concentration of phosphate and nitrate. You can simply hang the meter right above the sample to be tested for continuous measurement, and it will run without interruption on 12 VDC power supply. Measurements are highly accurate and the meter can be calibrated at one or two points. 1. 10.

This is normal with pH electrodes and they dissolve when rinsed with water. When not in use, rinse the electrode with water to minimize contamination and store it with a few drops of storage (HI 70300) or pH7 (HI 7007) solution in the protective cap. Always replace the protective cap after use. DO NOT USE DISTILLED OR DEIONIZED WATER FOR STORAGE PURPOSES. If the electrode has been left dry, soak the tip in a storage (HI 70300) or pH7 (HI 7007) solution for at least one hour to reactivate it. To minimize clogging and provide longer life for the pH electrode, it is recommended to clean it monthly. Immerse the tip of the electrode in HI 7061 for one hour and then rinse it with tap water. CALIBRATION For the greatest accuracy, frequent calibration of the instrument is recommended. In addition, the instrument must be recalibrated whenever: a) The pH electrode is replaced. [. . . ] To avoid electrical shock, do not use this instrument when voltages at the measurement surface exceed 24 VAC or 60 VDC. To avoid damages or burns, do not perform any measurement in microwave ovens.
