Anyone have instructions for Hannah Ph meter?

[headshake]

Lol! I'm not sure if I qualify as a big timer, but big timers such as myself... we tend to lose our own numbers pretty frequently... betcha that if he's big, and you manage to find that number, by the time you find it it will give you this message:
"We're sorry, but the TracFone number you are trying to reach is no longer in service"...

Good luck with this, and future, crappy meters! :jointsmile:

LMAO!

edit: the pen type or the mounted, possibly EC, TDM, PH type? which one is better/preferred?

So i took my newly purchased, used digital ph/ppm meter up to the local hydro shop so i could get it calibrated. Well the guy didn't know shit about hannah meters and after messing with it for a bit, he gave up. I did buy 7.0, 4.0 and ppm calibration solution. My question is: Why does it say while calibrating ph, "use 6.86"? it use to say use 7.01. then it goes to use 4.01. So I do all of that, using 7.0 where it says 6.86. Still reads funny. maybe i need a new electrode? Any info on the Rating: 5

ive been using my red pen hannah for a long time and havent had an issue.guess i got the only working one on the market.whats the issues that people are facing with there products? im honestly querious,i wonder if its on her last leg...so i dont mean to hi jack this thread but i thought it would be better than making another one on the same issue. so with that sed,what are the problems people are facing, i wonder how many people have jumped on the screw hannah band wagon.first hand info would be really nice to know and just might persued me to switch for better results.

shit...i just bought the red pen hannah the other day!! as im waitin for it to come in the mail i come across this damn thread....as i was scrolling down i was seeing nothing but negative comments about it til yours disrupt. i hope mine works

[disrupt86]

just be gentle with it. watch the glass probe and try not to knock it into anything,don't throw it around the room and you should be fine. but if you notice not a single person has sed any sort of realistic response or first hand response on what the issues are with it.

The calibration sucks, I cant get it down enough because thats as far as the little screw will go.

well i finally made the piece of crap get on the 7.01 calibration mode, and switched from 7.01 solution to 4.01 solution. The reason why mines a pos is it takes forever to stabalize, it will keep going up or down and sometimes it gives false readings. I've seen it show 7.5 on 6.5 water and after putting it in the 7.0 solution, and getting a steady 6.95-7.2 out of it, it will show 6.5 in the water, right where my test strips are showing. I think its fairly acurate but it needs to stay in the 7.0 solution before testing water.

Yup- the main problems are, that I've hear of or seen:
-Too delicate for growroom conditions
-Long stabilization time
-Inability to read low ionic strength solutions accurately- this is the most important.

Remind me to post a pH electrode maintenance sticky one of these days, lol... There are ways to slap a slow electrode back into shape.

can today be that day! just a friendly reminder God I love you stinky, always helping you're boys out!
