R-TEK 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 R-TEK 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 R-TEK 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 R-TEK 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 R-TEK 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.
