I believe the product that was mentioned a couple of days ago was
Mercoquant test strips for peroxide
 
They are available from
Merk KGaA
64271 Darmstadt
Germany
Tel (06151)720
 
They work  in the range of 0.5 - 25 mg per litre of H2O2 (Hydrogen
peroxide)
 
I assume the person requiring these  wants to test the natural
peroxide in honey.  These strips should work  in honey although the
stickyness may be a bit  disconccerting.
 
The strips work on a colour change reaction  to peroxide.
 
They are easy to use and reliable
 
Hope  all goes well
