Note: Some customers report that the product has data jumps, which is normal. (When using this product: After being placed in water, the data will always change slowly from the last decimal point, this is because the PH meter needs to adapt to the test environment. The data will be stable for about 1 minute when it is still, and this the final test data. In addition, if the water surface shakes, the data will also jump, so the test must ensure that the water surface is still.)
