Two-step operation for quick, reliable pH readings - Why you need it: get fast, stable pH values for a variety of liquids with minimal setup. Regular electrode care helps maintain accuracy and prolongs the life of the instrument. - Key benefits - Clear, stable readings once the value stops changing - Simple cleaning procedure to keep measurements trustworthy - Protective cover protects the electrode when not in use - Compact, easy-to-use design suitable for general purpose pH testing - How to use Step 1: Remove the protective cover, rinse the electrode with distilled water, and blot away moisture from the electrode and surrounding area with filter paper. Step 2: Press ON/OFF to power on, insert the instrument into the test solution, and submerge the electrode. Gently shake the instrument to drive away bubbles and read the value after it stabilizes. After testing, press ON/OFF to power off, rinse the electrode with clean water, and replace the protective cover. - Important attributes - Function: pH measurement - Performance: rapid stabilization for reliable readings - Maintenance: simple rinse and blot to preserve electrode condition - Design: protective cover included for storage and protection - Practical use scenarios - Hydroponics or nutrient solution: monitor pH to ensure optimal plant growth - Aquarium or pond water: maintain stable living conditions for aquatic life - Home beverages, cooking, or small-scale experiments: verify pH levels in liquids to support quality and consistency
