Hi, I have went through 4 ph meters, mostly cheap ones and a Hanna HI98103. I am never sure which to trust because I can calibrate them and then I get 4 different readings when I use them. I was going to buy another Hanna (same one) but realized I can just buy a replacement probe. Well I can buy the whole meter cheaper than just the probe! Kinda silly. I am in Canada and the cheapest price for the replacement is $35 (CDN) but after tax and shipping its $60…I can buy the whole meter on Amazon for $50 (all in).
Am i missing something? Time to buy a different brand? It seems like a lot of meters have replaceable probes but they seem hard to find.
Any thoughts or tips or suggestions would be greatly appreciated.
