Hi,
I'm finishing my first grow and have used the GH drops to measure the pH, take a long time to hit the pH with drops and the test is not correct... I hate the drops, sometimes I need more than 10 tests to get the pH between 5.5 and 7.0 so I decided to buy a digital meter for my second grow but it is not easy to find a consensus between the various models...
I'll probably buy it at ebay because they seem to be much cheaper but have a preference for European sellers, the models that I've been seeing are:
Adwa AD100 - 35 euros on Ebay (EU)
Adwa Waterproof AD11 - 38 euros on Ebay (EU)
Hanna 98107 - 43 euros on Ebay (US and EU)
Milwaukee pH600 - 45 euros in European stores, 29 euros on Ebay (US)
Milwaukee PH55 - 52 euros on Ebay (UK), is the only model which is cheaper in the European ebay
Hanna hi 98103 - 53 euros on Ebay (EU), 39 euros on Ebay (US)
(prices already with delivery)
Which of these models is the best? ... Why?
I do not mind having to calibrate it 3 in 3 months...
