Hi all
I've just ordered new stuff for my drop checker because I was running out. I've ordered the 4dkh and the Refil for the JBL Permenant C02 test which is labelled bromothymol blue. I've added 3ml of 4dkh solution and 3 drops of bromothymol blue, but the solution turns a dark blue. I thought it was supposed to turn green? Am I doing something wrong?
Thanks all
