What is the difference between Redox Indicator and pH Indicator ?

Ph is the meassurement of acid or base.
5-6 is consider nutral solution.

Redon gas is a radioactive gas that is emitted from the ground. Mostly in the old lead mine area. If the house is in such area it can get filled up with Redon gas, so you need to vent the redon out, the kit will tell you the presence of the Redon. They do have a kit to detect it.

I believe you meant to say Redon and not Redox.

I found two million references for Redox on one search engine alone.

Answer 2

The word Redox stands for Reduction and oxidation and the Redox indicators are those sustance which change their colour with substace of different oxidation state such as Diphenyl amine is a redox indicator which is colourless with Fe 2+ ion while it is of voilet colour with Fe 3+ ion. pH indicator exibit such change with substance of different pH or acid and base.Phenolphthlein,Methyl orenge, Metyl red are few exampls of pH indicator.
