pH/Ion meter SevenDirect SD50

I highly recommend this pH meter. It is easy to use and calibrate and also indispensable especially if you work with specific solutions. You can obtain reliable results. If you work with small volumes (3 ml) and if you use a magnet to homogenize your solution you can break the probe even if there is a protector, that’s why I highly recommend using it with high volumes.
