Step 1.Remove protective cap.

Step 2.First rinse the electrode with distilled water and suck it with filter paper.

Step 3.Turn the meter on by pressing “ON/OFF” key.

Step 4.Immerse the pH meter electrode in the solution to be tested (should not be over the immersion line).

Step 5.Stir gently and wait around 30 seconds till the reading stabilizes.

Step 6.After finishing, clear the electrode with pure water, turn the meter off by pressing “ON/OFF” key.

Step 7.Always replace the protective cap after use.

1.Turn on PH meter

2.Disolve each buffer solution in 250ML of distilled water

3.Immerse the electrode into the PH 6.86 solution,(under the temperature of 25)

4.Press the “CAL”(calibration)button for 5 seconds and release

-Display will start flashing 6.86

-Wait until the display stops flashing.

Rinse the electrode with distilled water and dry it with filter paper.

5. Immerse the electrode in PH 4.00 solution,

-Press“CAL”button for 5 seconds,then press and release immediately second time

-Reading will start flashing 4.00

-Wait until display stops flashing

Rinse and dry the electrode with distilled water as before.

6.Place the meter back to the buffer solution to test calibration.If incorrect,please repeat the calibration

7.If approximate PH of your test solution is known to be above 7.0,calibrate the meter using 6.86 and 9.18 solution. To do this,please follow the calibration chart,The third step is the calibration method for 9.18 point.

TDS Meter

A TDS meter (aka ppm pen, nutrient tester, tds stick) is an inexpensive and convenient digital tool to instantly check your overall water quality. TDS = Total Dissolved Solids, which is any salt, metal or mineral in the water. With the push of a button, the TDS can tell you your overall water purity level,which will be displayed on the screen in ppm (parts per million). The lower the TDS level, the purer the water, with 0 ppm being pure H2O. The TDS is great for checking your tap water quality, or knowing when to change a filter. (The meter does not test for biological contaminants.) The TDS is a great tool for drinking water,water filtration and purification, colloidal silver, hydroponics (test your nutrients), aquariums, RO/DI systems, pools and spas, commercial and industrial applications and more. The TDS is a rugged model that includes a protective carrying case. This is the world's most popular handheld TDS meter for industry professionals. ts Ideal for Commercial Use Its Includes a Carrying Case with Belt Clip Hold Function: Saves Measurements for Convenient Reading and Recording Highly Efficient and Accurate Due to Its Advanced Microprocessor Technology Built-in Digital Thermometer, Display: Large and Easy-to-read LCD Screen.
