It highlights the automatic temperature compensation feature and explains how to switch between Celsius and Fahrenheit by long-pressing the HOLD/TEMP button. Illustrations of thermometers indicate automatic heating and cooling to reach a reasonable temperature.

• To switch the temperature unit between Celsius (°C) and Fahrenheit (°F), long-press the Przycisk HOLD/TEMP. The display will change accordingly.
• The device features automatic temperature compensation (ATC) within its operating range of 0-60°C (32-140°F), ensuring accurate readings regardless of sample temperature fluctuations.

Kalibrowanie

Regular calibration ensures the accuracy of your meter. pH calibration is critical and should be performed using standard buffer solutions.

pH Calibration Procedure:

The meter supports 3-point pH calibration (pH 4.00, pH 6.86, pH 9.18). Use the provided pH buffer powders to prepare calibration solutions.

Opis obrazu: The main product image showing the 5-in-1 water quality tester immersed in a glass of water, alongside three packets of pH buffer powder (pH 6.86, pH 9.18, pH 4.00) and three LR44 batteries. This illustrates the components used for pH calibration.

1. Przygotuj roztwory buforowe: Dissolve each pH buffer powder (4.00, 6.86, 9.18) separately in 250ml of distilled water. Stir until fully dissolved.
2. Power On and Select pH Mode: Turn on the meter and switch to pH measurement mode.
3. Wejście w tryb kalibracji: Naciśnij i przytrzymaj Mode/CAL Button until "CAL" appears on the display.
4. Calibrate pH 6.86:
   • Rinse the probe with distilled water and immerse it into the pH 6.86 buffer solution.
   • Wait for the reading to stabilize. The meter will automatically recognize the buffer and calibrate.
   • Once calibrated, the display will show "PASS" or a similar confirmation, then return to measurement mode.
5. Calibrate pH 4.00:
   • Przepłucz sondę wodą destylowaną.
   • Zanurz sondę w roztworze buforowym o pH 4.00.
   • Naciśnij i przytrzymaj Mode/CAL Button again to enter calibration mode.
   • Wait for the reading to stabilize and for the meter to confirm calibration.
6. Calibrate pH 9.18 (Optional, for alkaline range):
   • Przepłucz sondę wodą destylowaną.
   • Zanurz sondę w roztworze buforowym o pH 9.18.
   • Naciśnij i przytrzymaj Mode/CAL Button wejść w tryb kalibracji.
   • Wait for the reading to stabilize and for the meter to confirm calibration.
7. Exit Calibration: After completing calibration, rinse the probe and store it.

Opis obrazu: This image visually demonstrates the pH calibration process. Three separate meters are shown, each immersed in a different pH buffer solution (pH 6.86, pH 4.00, and pH 9.18), with their displays showing the corresponding calibrated values. This illustrates the 3-point calibration method.

Notatka: TDS, EC, and Salinity measurements are typically factory calibrated and do not require user calibration. If readings appear inaccurate, ensure the probe is clean and consider recalibrating pH first, as it can influence other readings.

Understanding Water Quality Parameters

pH Levels:

pH measures the acidity or alkalinity of water on a scale from 0 to 14. A pH of 7 is neutral, below 7 is acidic, and above 7 is alkaline (basic).

Opis obrazu: A visual pH scale ranging from 0 (acidic) to 14 (alkaline), with 7 as neutral. Various common substances like battery acid, vinegar, orange juice, black coffee, water, seawater, baking soda, ammonia solution, bleach, and drain cleaner are plotted on the scale to illustrate their typical pH values. The water quality tester is shown alongside a glass of water, indicating its function in measuring pH.

• Drinking Water: EPA standards suggest a pH range of 6.5-8.5. Proper pH aids in mineral absorption.
• Hydroponics/Plants: Optimal pH levels are crucial for nutrient solubility and plant uptake.
• Akwaria: Maintaining specific pH levels is vital for the health and survival of aquatic organisms.

TDS (Total Dissolved Solids) and EC (Electrical Conductivity):

TDS measures the total concentration of dissolved substances in water, while EC measures the water's ability to conduct electricity, which is directly related to the concentration of ionized solids. Higher EC generally means higher TDS.

Opis obrazu: This image explains that conductivity is the total amount of dissolved solids and ions in water, reflecting water quality. It contrasts "Poor quality water" (depicted with unhealthy organs and skin) with "Quality water" (depicted with healthy organs and skin), implying the impact of water quality on health. The water quality tester is shown measuring a glass of water, with its display indicating a reading of 6.01 and 25.9°C. The measuring range for conductivity (0-10000uS/cm, 10.01-19.99ms, 20.1-400mS/CM) is also listed.

• Drinking Water: EPA recommends TDS below 500 mg/L (500 ppm). TDS levels between 50-500 ppm are generally considered suitable.
• Hydroponics/Plants: Specific TDS/EC ranges are required for different plants to ensure proper nutrient absorption.

Zasolenie:

Salinity measures the amount of salt dissolved in water.

• Totalizator piłkarski: Ideal salt levels for saltwater pools are typically between 2700-3400 ppm (3.2 ppt optimal).
• Akwaria: Essential for marine aquariums to replicate natural habitats.

Opis obrazu: A central image of the water quality tester surrounded by six circular icons depicting its various applications: Drinking Water, Hydroponic, Pool & SPA Water, Aquarium Water, Well Water, and Tap Water. This visually summarizes the versatility of the device.

Konserwacja

• Czyszczenie sondy: Always rinse the electrode probe with distilled water after each use to prevent contamination and residue buildup. Gently blot dry with a clean, soft cloth or tissue. Do not rub the electrode vigorously.
• Składowanie: Replace the protective cap after each use. Store the meter in a cool, dry place. For prolonged storage, ensure the electrode is kept moist (e.g., with a few drops of pH storage solution or distilled water in the cap, if recommended by manufacturer, otherwise keep dry).
• Wymiana baterii: Replace batteries when the low battery indicator appears on the display or when the device fails to power on.
• Unikaj silnych środków chemicznych: Do not use abrasive cleaners or harsh chemicals on the meter or probe, as this can damage the sensors.
