About Wiwanshop Digital PH Tester Meter Pocket Pen
This digital pen style pH meter is an ideal instrument for aquarium, fishing industry, swimming pool, school laboratory, food & beverage etc. Very excellent, accurate and durable. Note: The new digital tester shouldn't need to be adjusted. When you turn on the tester , you may find the measured value is not accurate and unstable, it's normal phenomenon. Put the digital tester in the liquid that you want to test about 1 minute and you can read the PH. If you find it not accurate, use the Calibration Adjustment Screwdriver (including) to adjust the adjustment trimmer.
