pH Color Standard

I've got the PS234S Test Kit and no pH color standard to match my pH test too... Anyone know where I can get one ?

Yes, order a K-1000 test kit from Taylor Technoligies. It is the same as originally came in your PS-234s. If you don't need the reagents then just order the 1000 comparator block, part number 9781. I don't know if Taylor sells them individually (they sell a six pack) but you can find them on the internet. Here is one place that sell them. Here is another.
