PLEASE Read Before Making Homemade H2SO4 pH Down! Important Info You NEED To Know!

DJ,

Yeah, I suppose being color impaired would have a pretty whoppin' effect on trying to read a colored reagent test! And red-green to boot! Have you thought about using a digital! I love mine, when I haven't broken them of course . My better one (the one I broke) also reads TDS/EC, and compensates for temp. It totally spoiled me. I miss it big time.

I'm not sure I'm understanding this correctly (entirely possible), but, just in case, let me restate that I sincerely hope that you weren't offended. No ill will, scout's honor.

I see in your signature that you are a Disabled Vet. I too am a Disabled Vet. Navy. And proud.

The one you broke sounds like the Hanna one that I'm saving up to buy. I think the one I'm looking at also give the solution temp as well as compensating for the temp.

What I was trying to say is usually I'm not offended by someone challenging anything I post. I also try to remind readers frequently to be skeptical of anything they read, especially my posts, and if it doesn't make sense then check it out. About the only time I get offended is when someone can't give a source for their opinion and become obnoxious neither of which apply to your posts. Your posts are well thought out, documented and usually over my head and I'm at least average in general knowledge even though I just getting started learning about growing. Fortunately I worked on my grandparent's farm until I turned 18 and moved away, so that gives me a little bit of general growing knowledge and have some local old timers here in town that try to be very helpful, but unfortunately, most of them are outdoor stealth growers with little knowledge about hydro or some of the newer techniques. For example, none of them had even heard about autoflowering varieties.

I'm an Air Force vet myself and proud of serving my country but not particularly proud of having been in the Air Force -- in fact I frequently call it the Air Farce because the discipline was erratic at best and most of the crap we put up with came from drunk E-9s that couldn't hold a job anywhere else.

Not to worry, if I'm offended, you will know it. Oh another thing that lights my fire is when someone starts being obnoxious to some one else. My pet peeve is when people use the forums to visit with each other in the middleof a thread rather than using PM for visiting.

Good smoking!

Mine's the Hanna HI-98129 and, yes, it gives solution temp as well as automatically compensating for temp when measuring pH and EC/TDS, something they call "ATC." Plus, you can specify the conversion factor for the EC/TDS measurements from 0.45 to 1.00, and you can do the same for the temp compensation coefficient beta, selection range being from 0 to like 2.4 or 2.5. On top of that it holds programs for single, double, or triple point pH cal, and single or double EC/TDS cal. It's freakin' awesome! Like I said, it has totally spoiled me. You're gonna love yours!

Word of warning from the genius who broke his! The ion permeable glass they make the pH electrode from is extremely thin and fragile! (At least mine was) I was used to my older Hanna that had a really sturdy glass 'trode with a permeable ceramic plug in the end. It was pretty much idiot-proof. Not so with the new one! Thank God the electrode is a replaceable cartridge. My new rule will be, "Never touch the 'trode with anything but liquid, e.g. nutes, cleaner, cal solution, etc.

I hope to see you at the Coffee Table so we can chew the fat about this and that.
