ATC Digital pH Meter Pen Model

Introduction

This product is a portable digital pH meter with an accuracy of 0.01.

It has the ability to be calibrated and comes with two calibration packages for pH 6.8 and 4 to calibrate the device.

Before use, the device sensor must be placed in distilled water for 24 hours to dry out.

After that, you can check the device and calibrate it if necessary.

After use, the device sensor must be washed and kept in distilled water in the off state.

The digital pH meter is one of the devices for determining the pH of liquids, or the measure of the acidity and alkalinity of water.

These devices are very necessary for aquariums and waters that need to be taken care of.

Turn on the device and immerse it in the solution to the specified amount until its electrode starts to detect correctly.

Usually, the number 7 is the healthiest for human consumption, and if the number is 2, 3, or 4, the water is acidic.

If the pH is above 8, the water is alkaline.

After use, turn off the pH meter.

If the measurement fluctuations are different, the electrode is dry or the battery is weak.

This device does not need to be calibrated or updated for 8 months to a year and as long as its accuracy has not decreased, and after this period, it must be recalibrated for accurate measurement.

For calibration, you can watch this video or perform the calibration according to this explanation:

Prepare the special solution and pour it into the purified water, then move the device slowly into it until the display is stable

Then use the special screwdriver inside the box to set the correction section to 6/9 or 7. Now the calibration is complete

If after a while, white crystals form on the lid of the pH meter, do not worry. This is normal for pH meter electrodes and will disappear when washed with purified water.

Use distilled or deionized water for cleaning.

Dear customer, please note that the presence of white crystals next to the electrode is normal because the device has been previously tested and calibrated.
