Professional pH Tester, Automatic Calibration Function and 0.00-14.00 Measuring Range for Portable Water, Aquarium, Hydroponics, Swimming Pool Measurement Range

HIGH QUALITY & DURABLE: It is highly accurate for a pH measurement range of 0 to 14, with a resolution of 0.01 pH, and an operating temperature of 0℃~60℃. It measures and displays the pH result simultaneously on the LCD screen, providing reliable and fast readings. Fast and Accurate Readings: Simply turn it on, dip the liquid into the display, and read. No need to work with color charts or test strips; the large LCD screen makes it easy to read. Accurate: This meter provides fast and accurate results with a resolution of 0.01 pH and high precision (0.01), measuring the full pH range of 0-14! WIDE APPLICATION: This pocket-sized pH meter is the ideal testing kit for both home and laboratory use. Ideal for testing water, swimming pools, aquariums, spas, hydroponics, food, wine, beer making, and more.

Auto Calibration: Requires no adjustment screwdriver, simply complete the calibration with the auto calibration button and includes buffer powders. 

This digital pH meter pen is an ideal instrument for any aquarium, fishing industry, swimming pools, school laboratories, food and beverage, etc. Measure and display pH result simultaneously with LCD display, reading reliable and fast. Pocket size for easy transport.

The pH meter could be used widely: test the pH value and quality of drinking water, aquariums, swimming pools, spas, tap water, well water, aquaculture, food processing, chemical experiment, ionized water, etc.

Features:

- Materials: High quality ABS

-Screen: Digital LCD

Probe type: precision glass bulb electrode

-Calibration method: automatic calibration

- Measuring range: 0.00 - 14.00 pH - Resolution: 0.01 pH - Accuracy: 0.01 pH - Batteries: 2 x 1.5V (AG-13 button cell not included) - Operating temperature: 0-60°C - Battery life: approx. 500 hours - Dimensions: 15.3 x 2.9 x 1.6 cm - Weight: 52g How to use: 1. Remove the protective cover. 2. Rinse the electrode with distilled water and dry it with filter paper. 3. Turn on the instrument; the electrode should be immersed in the test solution. 4. Stir gently until a stable reading is obtained. 5. Turn off the meter, rinse the electrode, and dry it with filter paper. Calibration Method: 1. Press the on/off button to turn on the power. 2. Dissolve each buffer solution in 250 ml of distilled water. 3. Immerse the electrode in the pH 6.86 solution (at a temperature of 25°C). - Press and hold the "CAL" button for 5 seconds and release. - The display will start flashing 6.86 - The display will stop flashing and show "End" - Rinse the electrode with distilled water and dry it with filter paper. 4. Immerse the electrode in the pH 4.01 solution (at a temperature of 25°C). - Press the "CAL" button for 5 seconds, then press and release it immediately a second time. - The display will start flashing 4.01. - The display will stop flashing and show "End". - Rinse the electrode with distilled water and dry it with filter paper. (The 2-point calibration is complete) 5. Once the calibration is complete, place it in the solution of known value to be detected. If the displayed value is within the error range, this means the calibration is accurate and can be used normally. If there is an error, repeat the calibration. 6. If you know that the approximate pH of the test solution is greater than 7.0, calibrate the tool using solutions 6.86 and 9.18. To do this, please follow the calibration table. The third step is the 9.18-point calibration method. Package Contents: 1 pH Meter CAUTIONS: ✔ Clean the electrode with distilled water before and after each use. ✔ Be careful with the glass probe as it can be somewhat fragile during use. ✔ Remember to gently wipe it with a soft, clean cloth when finished before covering it. ✔ Opening the battery compartment or replacing the battery will require recalibrating the meter.
