The pH meter is perfect device for testing the acidity or alkalinity of liquids. It is very easy to use - just immerse the electrode to get accurate, fast readings. Specification • Resolution: 0.1pH • Range: 0.0 - 14.0pH • Accuracy: ± 0.1pH(at 20°C/ 68°F) • ATC (Automatic Temperature Compensation) can measure pH accurate in fluctuating temperatures between 0~50℃ • Typical EMC DEV: ± 0.2pH • Batteries: 3 x 1.5V (AG-13 Button Battery) • Life: approx. 700hours of use • Environment: 0°C ~ 50°C(32°F - 122°F) • Relative Humidity: • Size: 15 cm x 2.9cm x 2cm • Trimming: by potentiometer • Weight: 51g • pH calibration solution is not included Package include: 1 x PH Meter 1 x Screwdriver (for calibration) 1 x 4.00 Buffer Powder (sachets can be used with distilled or tap water) 1 x 6.86 Buffer Powder (sachets can be used with distilled or tap water) 1 x User's manual Note: *The meter was calibrated before off the factory. Do not need to calibrate the meter when first use. *The glass electrode is fragile, treat it carefully. Don't touch it by hard tools or fingers. *Please do not immerse the meter into the solution over the "warning line", to avoid damage to the circuit board. *If the "cal'(calibration) button is pressed and electrode exposed to air for a long time,calibration is required.
