Pinpoint pH 4.00 calibration solution

Do you carry pH 4.00 calibration packets for American Marine pH monitors? I see 7.00 and 10.00 but not 4.00. Thanks.

Hi,

We do not stock 4.00, but could special order it. The 4.00 and 10.00 do the exact same calibration though, so you can use 4 or 10 and get the same result, then of course the 7.00.

thanks
