Thanks for the info Shed , now i also know i need to store this Ph pen correctly . Damn and i am not really using it for myself at the time (until things change) After reading some on it also can >>. Always keep your pH electrode moist. We recommend that you store your electrode in a solution of 4 M KCl. If 4 M KCl is not available, use a pH 4 or 7 buffer solution. DO NOT store electrode in distilled or deionized water—this will cause ions to leach out of the glass bulb and render your electrode useless.Jul 21, 2021 From Google ..Yeah maybe i can put this bad soil where i don't want grass to grow in my yard LOL
