Digital pH Meter, Professional pH Tester, Electric Digital Pocket pH Meter for Water, Hydroponics Tester, LCD Screen Pen, Automatic Calibration Function and 0.00-14.00 Measurement Range

Fast and accurate readings – simply turn it on, dip in liquid, and display the reading; no need to work with color charts or test strips; the large digital screen makes reading easy.

Automatic calibration – No screwdriver adjustments required; simply complete calibration with the automatic calibration button and the powder buffer is included.

ATC function – Due to the variability of factors, the temperature of the test objects may have been slightly different, which may result in an inaccurate reading.

The ATC function can automatically compensate for the temperature of the test objects, preventing inaccurate readings.

Portable Design – Compact pen-style pocket and carrying case make it easy to slip into your pocket or bag and take with you everywhere.

Application – Water analysis in swimming pools, ponds, spas, laboratory testing, food processing, hydroponics, aquaculture, and even home aquariums.

Product Description

pH Meter Calibration Methods:

1. Mix one packet of correction powder with 250 ml of water and stir gently. Insert the pen to detect the pH value of the solution; if the pen reads 6.8, the reading is accurate.

2. If the display deviates from 6.8, use a small screwdriver to adjust the calibration potentiometer (opening on the back) until the value of the reference buffer solution at room temperature is part of the pH value.

3. Do not correct when the probe is out of water!

Easy to use:

1. Remove the protective cap.

2. First, wash the electrode with distilled water and dry it with filter paper.

3. Turn on the pH meter using the "ON-OFF" switch on top of the battery compartment.

4. After use, close the pH meter, rinse the electrode with distilled water, and replace the protective cap.
