The ph meter or controller is also used in the cosmetics industry in which the chemicals used in the cosmetics products are checked using a Instrument so that the harsh chemicals do not hamper the skin. Even though the skin has a ph but if harsh chemical products are used on the skin, the ph may be disturbed causing rashes and itching, so industries making cosmetics which are used on face and hair, keep a strict check on the ph using the PH Meter.
