Bestnify PH METER Specification: Measure range: 0.00- 16.00PH Resolution: 0.01PH Accuracy: ±2% Power Supply: 2*1.5V Operating Temperature: 0°C - 60°C / 32°F - 140°F Dimension: 155mm* 31mm * 18mm / 6.1" × 1.2" × 0.7" Weight: 50g / 1.76oz Calibration: 1. Dissolve PH buffer powder in 250ml of distilled water. 2. Turn on PH meter and clean the electrode in distilled water, then immerse the electrode in the PH standard solution. 3. Press “ CAL” button, wait until the reading is the same as the PH value of buffer powder and steady. 4. Clean electrode with distilled water and dry it. Packaging: - 1×Digital PH Meter - 1×Carrying Case - 1×User Manual - 3×PH buffer powder Tip: - Pls make the connecting shrapnel of the battery case orient towards the side of LCD display, when you install battery case into the PH meter, to avoid battery case that are got stuck in PH tester. - Pls recalibrate the PH tester after open the battery case or replace the battery. - Pls clean the electrode with distilled water before or after use it. - Pls don't drop distilled water in protection cap to maintain the agile grass probe of the PH meter, pls use storage solution or standard solution if needed.
- ☛AUTOMATIC CALIBRATION：Just one touch button can help you calibrate the digital pH tester. You can calibrate the digital pH meter with pressing the button ' CAL' and immersing the electrode into the solution. Give pH readings almost instantly.
- ☛CONVENIENCE USE: We've got covered all pH testing occasion you need. Suitable for testing pH balance of drinking water, pool, aquarium, RO system, Spa, or hydroponics; Appropriate for wide range of applications. Great for kids school science experiments.
- ☛AUTOMATIC TEMPERATURE COMPENSATION: No more need to take care about the temperature of testing liquid, as pH meter has built in( ATC) automatic temperature compensation, so that it can accurately determine pH value of the sample at any temperature in a range of 0°C - 80°C (32°F - 176°F).
- ☛FAST AND ACCURATE : Ensure your pool, general hydroponics pH or even drinking water has a perfect pH balance and safe for use with the Tester precision pH accuracy. The tester has a sensitive electrode sensor to read accurate pH levels.
