I did look at these but my view is that as you don't need to know how much chlorine is present, just whether there is any these are a bit of overkill.
So I use the DPD 4 tablets per Manky Sanke's method.

Basically dissolve a tablet in a water sample, any pink colour and you've got chlorine present. But it's important to do it as described -
