Question regarding electromagnetic water conditioner

(Question received through email)

Dear sir/madam,

I am interested to know whether the electromagnetic water conditioners are certified by you/other bodies/institutions for use as anti-scale forming/scale-inhibiting  device/method  for routine domestic  use. Have  you conducted studies/ experiments/research to prove their effectiveness in preventing scale formation on tubes? If so, kindly share with me the relevant data you have so that I can purchase them with confidence.

I request an early and detailed reply.
