I provided a link that showed the one that I own. It says too make sure the soil is very wet with nuetral water to get a good reading or something?
AKickedBowl Reviewed by AKickedBowl on . PH meter questions I recently bought this pH meter and have some questions. Its the one thats electronic by Rapitest. 1. Does it need to be calibrated? I feel like that's a stupid question but I wanna makes sure I'm doing things properly. 2. If it does, I only have the ph 7.0 calibration fluid, is this sufficient? 3. How do I do this exactly? (I've researched a little bit but I'm still confused) 4. ANOTHER really dumb question I have is does it have an on off button/function? Rating: 5
