I bought the PH80 from them @ R875, and it is very accurate.
I suppose you get what you pay for.

 

Spraytech in Cape Town sell Milwaukee ones - they are laboratory quality and VERY accurate - buy the 3 buffer solutions also - you have to have the buffer solutions to calibrate the pen regularly.
I have the pH and temp together model. Overnight courier gets them to Jhb fast. They are not cheap but you cannot afford to buy cheap when buying electronic meters !!!

 

Same with the PH80 and PH200 from Design Water.
You get pH buffers for 4.0, 7.0 and 10.0, which are needed to calibrate the devices.
A good idea is to also get the Electrode storage solution, that keeps the electrode moist when in storage.

I had my PH80 tested against laboratory grade equipment, and the pH was accurate to within 0.1 points, while the thermometer was also accurate to within 0.1°C.
Not bad for a digital pen that cost about R1000.

My very cheap one works very well.

May just calibrate to make sure

 

I find the HTH test kit to be more accurate reading on the color chart one gets
