Featuring a three-point calibration method with simple calibration procedures, the Dr.meter pH testing device can automatically identify the calibration liquid to give you the pH reading almost in a flash.
  • ▶ 【Convenient pH Value Reading】: Get the job done with ease. Ready to read the pH value? Just know the liquid quality with one-button lock reading function. It really is that easy.
  • ▶ 【utomatic Temperature Compensation】: With automatic temperature compensation function (ATC), the Dr.meter pH meter can solve possible inaccuracy caused by the change of liquid temperature, making the pH more accurate.
  • ▶ 【High Accuracy】: Have you ever seen a digital pH meter designed with premium accuracy together with fast response? You can do now with Dr.meter pH tester. Equipped with high-quality and high-accuracy algorithm chip and electrode, the Dr.meter pH tester is the perfect choice for solution quality testing.
  • ▶ 【Warm Tips】: After each use, please confirm whether the sponge in the electrode protective cover is wet. If not, please drop in an appropriate amount of pH 4.0 solution in time. If you have not used the pH meter for a long time and forget to add PH4.0 buffer to the sponge, please put the composite electrode into the pH4.0 buffer or tap water for more than 24H before use, and then calibrate and use it.

Product Description

ph meter
ph pen

The Dr.meter pH meter uses a 3-point calibration method, calibrating the electrode to solutions of pH 6.86, pH 4.00, and pH 9.18.

How to Calibrate the pH Meter

1. Before calibration, prepare a beaker containing a pH 4.00 solution, a beaker with pH 6.86 solution, and a beaker pH 9.18 solution. Make sure that each solution is 250ml and at a stable temperature of 25℃

2. Prepare 3 separate beakers with distilled water.

3. Press the ON/OFF button to turn on the meter.

4. Remove the cap and immerse the electrode into the PH6.86 buffer solution. Stir gently and wait for the value to stabilize.

5. Press and hold the CAL button for 3 seconds. Hold the electrode into the solution until the LCD screen displays a value of pH 6.86.

6. Rinse the electrode with distilled water and blot dry. Repeat steps 4, 5, and 6 for the pH 4.00 and pH 9.18 solutions.

1.Remove the protective cap from the handheld pH meter. Put the composite electrode into distilled water, and slowly stir it for 5-10 seconds, then take out the pH meter and spin-dry it.

2.Press the ON/OFF button to turn on the unit. Dip the electrode in the target solution, making sure the whole electrode is submerged.

3. Stir the solution gently and wait for the value to stabilize. The LCD screen will display both the temperature and pH.

It shows different values of the same solution. After ...
It shows different values of the same solution. After recalibration there is the same situation, several times measured the same solution and each time it showed different value of pH. Returned it and bought cheap one what does it job perfectly!p.s. I change my review with one star to four stars, because I was contacted by the customer support and offered another meter.I calibrated the meter twice. Now its reading close but still is not reliable. There is not definitely 0.01 accuracy! At the same time I cannot claim that another meter is high accuracy also.In general, I got the idea about my pH meters and will still looking for much more reliable meter.
