ok so the directions say to set the probe in a phosphate buffer solution with a steady PH. well i dont have nor know where to get phosphate buffer solution so my question is........ is there any other solution with a known constant ph that i can use as a buffer solution?????? i do have the ph strips and the ph up and down kit< but i got this bad ass digital ph reader a while ago and i would like to eventually put it to use.. any info from the worlds greatest minds would be appreciated..
You need buffer solution. Check where you bought the probe, or you can find it online or at a hydro store. Possibly a specialized nursery/garden center (but not at Home Depot, Lowes, etc). While there might be home brew DIY buffer recipes, I would stick with what the mfgr provides/recommends -- you are, after all, trying to accurately calibrate a precision instrument.
good point. i might as well wait the 5-7 days for the solution, the meter has been in my closet for almost a year. whats another week.. thanks toasty...stay frosty>>>
yea man definetly pick up some buffer ph solution. worth the wait. general hydroponics makes a good one. comes in lil satchels. one time users. pretty conveniant good luck man
