Customer: 
Dear Sir or Madam, we have a BWT system. Now we need the pH probe and the redox probe, but unfortunately we don't know which ones we need. 
 
 
 
Thank you for the super fast response. I will talk to my husband briefly and then get back to you. 
I spoke to my husband and he told me to order the probes. As I saw, I can do that through the links you sent me. I also wish you a nice day. 
Hello again, I wanted to place an order, but I'm having trouble with the free shipping, the button is inactive. 
I selected it, but it only works for shipping with shipping costs. 
No, it only works with costs and delivery to a pickup station. 
Preferably on invoice if possible. 
Correct. 
Okay, got it. Thank you.
