hey Yo my new friends. Am thinkn bout going ahead and pull trigger for a higher end ph pen. (as haven't mixed nutes or ph up/down enough times to know off hand.)
Whats the.. (well best is subjective) but most used and trusted PH Pen?
three im thinking on:
Blueslab ph pen $120
Apera Instruments AI209 $49
AC infinity (most thinkn on as my setup is AC I.) $80.. or might do $150 for pro 4in1 tester
there are a hundreds of threads on this. just do a search. i personally use apera 60 series ec and ph meters.
top brands to look for are blue lab, hanna, h/m, and apera. they all build professional lab quality level meters. make sure you get a higher end model with probe ends that are removable, the ph meter bulbs can break and it's far cheaper to replace the end than the whole probe.
stay away from the all-in-one ec+ph probes. the ends are triple the price if you break the ph bulb. it's only ever the ph bulb that breaks. get a separate dedicated ph, and a dedicated ec meter.
apera will often come with it's own storage case and accessories which is super nice.
