Item Description
  • BEFORE USE: Put the included potassium chloride powder into 20ml of pure water and mix well. Then put the probe into the solution for 24 hours, take it out and clean the residual solution on the surface of the sensitive bulb. Now, you can start to calibrate. (Note: If the sponge is wet enough, please skip this step.)
  • DURING USE: If there is inaccurate calibration, repeat the step of 'Before Use'. If using your own potassium chloride powder, prepare the solution by adding 61.5g of KCL into 250ml of water. Then, put the probe into the solution for 24 hours, take it out and clean the residual solution on the surface of the sensitive bulb. Now, you can start to calibrate.
  • AFTER USE: To ensure the activity of the sensitive bulb, add a drop of newly prepared potassium chloride solution into the sponge inside the probe cover. Also, to better maintain the activity of the sensitive bulb, add the solution to the sponge every two months.
  • ▶ 【Notification】Calibrate once per week if you often test solution of PH 10, or once per half month for neutral solutions. The 250ml calibration solution for multiple uses (10ml or so each time). Then rinse the electrode with pure water before next test. Rinse and rest 3-5 min before conversing from strong acid to strong alkaline and vice versa.
  • ▶ 【Clear Digital Display with Alerts】 Tired of squinting at a small screen to get your readings? Enjoy this PH meter's large, backlit LCD screen that displays the information in an intuitive layout so you can still see even in low visibility situations. When the PH value is lower than 3.5 or higher than 12.5, the white digital display will change to red and flash to alert you.
  • ▶ 【Automatic Calibration】 We make your job faster and easier than ever with this convenient PH tester! With the 3-point calibration procedures, your PH testing device will automatically identify the calibration solutions to give you your reading in a snap.
  • ▶ 【Automatic Temperature Compensation】 Temperature can affect reading levels, our PH meter's automatic temperature compensation can ensure that you're getting the best possible reading. Unlike other PH meters that only have a range of 0-50 degree, ours has a even better range of 0-70 degree, so you can test with confidence in any environment.
  • ▶ 【User Friendly】 You can easily replace the 2 AAA batteries when it's time, and you can also activate the 15-minute auto-off functionality to save battery. Plus, it even comes with a storage case to keep it safe and protected when you're on the go.

1.Prepare 3 beakers separately containing pH4.00, pH6.86 and pH9.18 solution, and each solution is 250ml at a stable temperature of 25 Celsius.
3.Immerse the electrode into the PH4.00 buffer solution. Stir gently and wait for the value to stabilize.
4.Press and hold the CAL button for 5 seconds until the LCD screen displays pH 4.00.
5.Rinse the electrode with distilled water and blot dry. Repeat step 3, 4, 5 for the pH 6.86 and pH 9.18 solutions.
The glass probe is blown in shape at a high temperature above 1000 Celsius degree. Covered with the glass-sensitive film with low resistance, it's quick and easy to respond with H+ in the solution, which greatly increases the sensitivity and accuracy up to 0.01.
Before turning on the device, press and hold the ON/OFF button and backlight button simultaneously and the LCD display will show Celsius or Fahrenheit. Press the ON/OFF button to select your desired unit; after that, press and hold the ON/OFF button to save the selection.
