PCE Instruments PCE-228P



PCE-228P is a portable handheld pH meter with electrodes for measuring the pH and temperature of cosmetic products such as shampoos, conditioners, lotions and creams. This easy-to-use cosmetics pH meter saves all measured values to an included SD card memory in a Microsoft Excel-compatible format. For more information specific to this meter, please read the highlights and specifications. 
Cosmetics production requires a delicate balance of beauty and science. Cosmetic products must appeal to the senses as well as contain safe ingredients effective at improving the condition of the skin or hair. 
To achieve this, aspects such as viscosity, color and shelf life are tested during the cosmetic production process. In addition, the pH level of a cosmetic product is measured to ensure compatibility with the body’s own pH values and to verify the product’s quality and safety. For example, if the pH level of a shampoo is too acidic or too alkaline, at a minimum the shampoo could cause skin irritation, among other undesirable or harmful effects.
