Fast PH Who determination

Because different devices are offered here, it should be mentioned that my review is from the pH meter by Mudder.
I live on a Spanish island and also run a pool. Always late February to early March they should change the pool from winter mode to the regular mode of operation due to the ever increasing temperatures here. The pool is made of cleaned sand filter for continuous operation and laid the first chlorine tablets into the skimmer. From now is forcing the water quality required to keep in mind. So far, I always use test strips which are briefly dipped into the water and half a minute are matched to a comparison scale. Easier and faster with this pH meter.
The unit is well protected in a small plastic box including manual and a calibration kit. The pH meter must be calibrated once before commissioning. For this purpose are ready 2 bags powder and a screwdriver in the package. The calibration is well explained and is done in a few minutes. Then the device is ready for operation. To measure the meter is simply held in the water. The PH value is displayed directly on the device.
The unit is well made, the manual is easy to understand. Overall I am very satisfied with the pH meter.
