I tried searching and found several suggestions, but all were dead links. Maybe time for some updates?
Something like the ≈$50ish Apera would be great, but not so budget friendly.
I’d like to find a reliable set for less than just the Apera TDS/EC, if possible, but don’t want to scrape the bottom of the barrel and end up with inaccurate meters.
All suggestions are welcome. Thank you in advance.
