Wouldn't you know, I lost the damn manual... Checker by Hanna PH meter
Found the calibration instructions, But it says I need a PH 4.0 in adition to the PH 7.0 solution, and it only came with the PH 7.0....
There aren't any hydroponic shops around here.. However there is an aquarium store... do you think they would sell it? dunno what to do...
I know what you mean.I have the hanna checker and on the box it has a web address,HANNA instruments® Worldwide you can go there and most likely find the manual.It seens I cant fine my manual.So I will be doing the same. Here's the place I got my checker from Sunstone Herbals - Natural Remedies for the New Millennium and they have the pH solutions too.I got the packets for a $1.50 each,you need both the 4.01 and 7.01 solution to calibrate with.Oh you are in luck I found some of the manual thers a 1-800-426-6287 for technical support or [email protected] there you go,hope that helps.PEACE

Does anyone know if you can use the 7.01 buffer solution for a storage solution as well?
