Key benefits - Provides fast, stable pH readings of liquids with a simple handheld design. - Two-step operation and minimal maintenance for reliable everyday use. - Clean the electrode with distilled water and dry with filter paper to help prevent contamination. - Protective cover keeps the electrode protected between measurements and extends life. - Readings appear after the value stabilizes, reducing guesswork. How to use Step 1: Remove the protective cover, clean the electrode with distilled water, and use filter paper to absorb moisture from the electrode and surrounding area. Step 2: Turn on with ON/OFF, insert the instrument into the test solution, immerse the electrode, gently shake to drive away bubbles, and read the displayed number after it stabilizes. Step 3: After use, turn off with ON/OFF, rinse the electrode with clean water, and put on the protective cover. Key attributes - Function: handheld pH meter for liquid testing with a stabilized reading. - Performance: stabilizing readings reduce measurement variation; bubble removal improves accuracy. - Maintenance: simple cleaning with distilled water and protective-cap storage extend electrode life. - Usability: straightforward two-step procedure for quick measurements. Use scenarios - Hydroponics: monitor nutrient solution pH to support healthy plant growth. - Aquarium or pond care: keep water pH within safe ranges for fish and aquatic plants. - Home brewing or beverage prep: adjust pH to ensure flavor stability and quality.
