It was the cheapest combo meter I could find and I am sure it is worth every penny! I think the accuracy is good enough that I can compare readings to other meters and at least be in the ballpark. When comparing readings to itself I don't think there is any real concern, other than perhaps the durability/quality of the sensors. There are calibration screws for pH and ppm so if measurement accuracy is a concern you could buy or make up standard solutions to observe any drift.Yeah, I've seen it and have it on my wishlist cause I'm switching to coco DTW and plan to run an external 15gal res. Is it worth it? Have found it for ~80$ (70€) on e3ay but with mixed reviews. Some praise it, others complain about dry PH electrodes. What do you think about it? Are replacement electrodes available in case you need a new one. Looks like the EC electrode is not changable(at least without opening the case) but they usually last much longer.
When I did environmental work we used multi thousand dollar a ysi, or hach water quality meters, pH probes dried out when in long term storage. DO senors were the worst, trying to fill them and get the membrane on with no bubbles if fucking wyoming wind storm? GFL.
Did the company take care of the issue or did people have to buy a new probe? IIRC the ec and pH probe part nos. were listen on the porly translated instruction sheet. You can tell I didn't do a whole lot a research.
