High-Accuracy Digital pH Meter: Your Essential Tool for Precise pH Measurement
Ensure the health and quality of your liquids and certain foods with the Digital pH Meter. Designed for high precision and ease of use, this pocket-sized pH tester provides accurate and stable readings in just a few seconds, making it an indispensable tool for a wide range of applications.
Unparalleled Accuracy and Reliability
The pH meter boasts a high precision pH accuracy of ±0.01 pH and a resolution of 0.01 pH across its full 0.00-14.00 pH measuring range. This ensures highly reliable results for critical measurements. A key feature is its Automatic Temperature Compensation (ATC), which intelligently adjusts for temperature variations, eliminating the need for manual temperature considerations and further enhancing measurement accuracy.
Effortless Auto-Calibration for Consistent Performance
Regular calibration is vital for any pH meter to maintain accuracy, as electrodes can change over time. The meter simplifies this process with its user-friendly auto-calibration mode.
Calibration Steps:
• Prepare individual solutions using the included calibration buffer powders (pH 6.86, pH 4.0, and pH 9.18). Distilled water is essential for mixing these buffers and for rinsing the electrode.
• Power on the meter.
• Immerse the electrode (without submerging past the immersion line) into the first buffer solution.
• Press and hold the CAL button for 5 seconds to enter calibration mode. The meter will flash and automatically recognise the buffer, completing the calibration point.
• Rinse the electrode thoroughly with distilled water and gently pat dry with a lint-free tissue between each buffer.
• Repeat the process for the remaining buffer solutions as indicated by your meter, following any specific button press sequences required.
• Once all calibration points are complete and the display stabilises, your meter is ready for use, ensuring its readings are adjusted to any changes in the electrode.
Wide-Ranging Applications
This versatile pH tester is an essential tool for maintaining optimal pH levels in various settings:
• Water Quality Testing: Ideal for drinking water, swimming pools, aquariums, RO systems, and spas.
• Hydroponics: Crucial for managing nutrient solutions and plant growth environments.
• Food and Beverages: Perfect for testing the pH of fruit juice, chili sauce, seasoning sauce, syrups, honey, jam, canned goods, sourdough bread dough, cheeses, and yogurt.
• Personal Care: Useful for checking the pH of homemade toothpaste and face cream.
• General Use: Applicable in scientific research, environmental monitoring, and healthcare, and for ensuring the safety of aquatic pet water sources.
Designed for Convenience and Durability
The Digital pH Meter is designed for portability and ease of handling. It comes with a protective carrying case and pre-installed LR44 batteries, allowing you to start testing right away. Its compact, pocket-sized design makes it easy to transport and use anywhere.
Care and Maintenance for Extended Life
To ensure the longevity and continued accuracy of your pH meter:
• Always rinse the electrode with distilled water after each use and gently blot it dry. It is recommended to keep the pH probe moist when storing, often in a storage solution or by not drying the probe itself before capping.
• Replace the protective cap and store the meter in its case when not in use.
• Avoid exposing the meter to extreme temperatures or submerging it past the immersion line.
• Replace calibration solutions regularly, especially if they show any signs of contamination like mold or film.
