Semlos 0.01 Resolution Digital PH Meter

This is a decent quality budget PH meter and at the current Amazon price of just £11.99 I doubt if you will find a better.

There was no product box as such but the meter was supplied in a rigid plastic case. Along with the meter itself were six buffer powder packs and a well written and easy to read User Guide which I reproduce on the end of my unboxing video.

The device itself is similar to a large felt tip marker in size and has a pocket clip and removable top to protect the sensor. The LCD screen is large, easy to read and is backlit. Next to the screen are the two buttons, one to switch on and test and the other for calibration. The unit takes two 1.5V AG-13 replaceable button batteries and comes with batteries pre installed. It all seems well made and robust enough for regular use.

It has a measuring range from 0.00 -14.00 PH with a claimed accuracy of 0.01 pH 0.01 pH, which I have no reason to doubt. The unit comes factory calibrated but should it need to be re calibrated the set of six buffer powders can be used to do so. Replacement powders are available on Amazon and elsewhere should you need them.

Using the device could not be simpler. Just switch on and dip the testing head into the fluid to be tested and the reading will show on the screen. It is important to clean the head after using in distilled water and with a PH neutral cloth or paper. Failure to do so could lead to inaccurate readings later.

I have found the device works well and so far as I can tell is very accurate. The price is as good as you are going to get and the build quality is fine for all but heavy duty professional use.

If you need a good quality PH meter at a great price then this would be a great choice.
