Marfied Eco pH Duo pH Meter

This is the EcoPeeHaa Duo by Murphy.
It has only been used a few times and is generally in beautiful condition.
It makes aquarium management much easier by allowing you to easily and accurately measure pH, which is essential for water quality management.
Visual checks can easily lead to measurement errors, but it's very convenient because it displays numerical values digitally!
The power turns on without any issues.

I am selling it because I am retiring and no longer need it.
It has been used about 30 times.
It is still in good working condition, and has been calibrated with the included calibration solution, so you can use it right away.
If you are looking for one, please consider it!
