Don't know much about the tester - i use the chemical test kits, but the seller has 100% good feedback, so less likely to be a rip-off merchant

Could be a bit expensive IMHO

The Ph pen meters do the job but require recallibration rather often so you need to be buying distilled water, but if you buy one, get a good model. We are going to be putting digital ones on our two big tanks, yet they are the one that has the screen that sits on top of the tank and the probe in the water permanently (not the pen model like you have linked). The one we are looking at are excellent. I would prefer a good digital Ph over chemical. Chemical testers we have found vary.

The electronic ones are the only ones that are pretty accurate provided you use them according to instructions and keep the probes clean. The price is pretty good for the accuracy claimed in the specs. In my view it would be a good product if you were concerned about knowing your pH with that accuracy--- which I am not. I have an accurate electronic thermometer which I use to establish temperature because most of the thermostats are not too accurate but I don't worry too much in Christchurch about pH when water changes are so easy and rainwater is so easy to collect.
