Feature(may vary by option.)
●【Aplication】As a tool to improve the quality of life. Can be used to test drinking water, swimming pools, PH balance in an aquarium, RO system, spa, or hydroponics. All the environments that need to test PH values can use this tester to get accurate data.
●【How to use calibration】Place the tester in a calibration solution. Press CAL for 3 seconds to enter the calibration mode, and press in turn to select the powders corresponding to 6.86, 4.00, and 9.18 to complete the calibration.
●【Easy to use】turn on the switch, place the probe into the water, and stir (make the small glass ball fully contact the liquid) and the value can be read when the value is stable.
●【Automatic Temperature Compensation-ATC】There is no need to care about the temperature of the liquid being measured. The PH meter has an automatic temperature compensation function.
●【Mini Size】The mini size of the pH meter allows you to easily put it in your pocket, so you can take measurements anytime, anywhere. It can help you to make a pH test anywhere, you just take it to the pool, on a trip, to the beach, camping, etc.

Description
Divolight provides you with premium water testing equipment as a microlab in your pocket.
You have to know!!!
You can use reliable, accurate digital equipment. Not necessary to use color strips, guessing looking at the color change.
You can accurately know your quality of life, by using Divolight combo testers for water.
The technical definition of pH is that it is a measure of the activity of the hydrogen ion (H+) and is reported as the reciprocal of the logarithm of the hydrogen ion activity. Therefore, water with a pH of 7 has 10-7 moles per liter of hydrogen ions, whereas a pH of 6 has 10-6 moles per liter. The pH scale ranges from 0 to 14.
How pH affects aquatic life
Changes in the pH value of water are important to many organisms. Most organisms have adapted to life in water of a specific pH and may die if it changes even slightly. This is especially true of aquatic macroinvertebrates and fish eggs and fry.
The pH is a critical factor determining the health of a waterway. The factors that control it are complicated. As with many environmental concerns, we need to be aware of the implications of any impacts we have upon the environment.
The pH of pure water (H20) is 7 at 25°C, but when exposed to the carbon dioxide in the atmosphere, this equilibrium results in a pH of approximately 5.2. Because of the association of pH with atmospheric gasses and temperature, it is strongly recommended that the water be tested as soon as possible. The pH of the water is not a measure of the strength of the acidic or basic solution and alone does not provide a complete picture of the characteristics or limitations of the water supply.
Use-related problems with PH testers:

|
|
|---|---|---|---|
|
• The value bounces erratically when the PH meter is turned on in the air, which is a common occurrence. It is impossible to utilize the value in the air as a reference |
• The water must be gently stirred (to remove the bubbles attached to the probe) and given time to stabilize before the PH meter can measure the water. During the test, it is common for the result to rise or fall abruptly. Do not simply insert it and start reading it right away. |
• A typical phenomenon of the PH electrode is the appearance of white crystalline salt around the electrode of the PH meter. Because measured solutions are drying, salt is deposited on the sensors surface. The electrode can be submerged in RO or distilled water for a few hours and cleaning it. Note, when you use the first time or resume use after a long time, it is recommended to make this procedure. |
· The electrode for the PH meter is made of fragile glass. Please dont touch it with your hands or drop it. Test the water only up to 50°C. Avoid testing the powerful acid and alkali because doing so will rupture the electrode glass. |

Calibration
There are three options for the calibration of the pH tester.
1. Calibration by one-point. In this case, the accuracy will be 0.5pH
2. Calibration by the two-point. In that case, the accuracy will be 0.2pH.
3. Calibration by the three-point. In that case, the accuracy will be 0.1pH.
1. The one-point calibration.
Create a 6.86 pH solution.
Take 250 ml of distilled or RO water.
Open the pack (6.86pH) and completely dissolve all powder. (There shouldnt be left powder in the pack and at the bottom of a glass)
1. Remove the protective cap.
2 First, rinse the electrode with distilled water, then suck it with filter paper.
3. Turn on the pH tester by pressing the "ON/OFF" button.
4. Immerse the pH tester in the solution (6.86pH) and wait for over 5 min. (CAN NOT BE OVER THE IMMERSION LINE)
5. Stir gently for ten seconds, and press "CAL" to see the displaying number going to 5, then release to find the 6.86pH calibration point.
6 The display starts flashing 6.86. You have to wait until the flashing stops before taking the tester out of the solution.
7. Calibration was ended. Dont forget to rinse the electrode with distilled water, then suck it with filter paper after calibration.
