Skin & Scalp Portable pH / Temperature Meter with HI-14143/50

Hanna HI-99181 Skin & Scalp Portable pH / Temperature Meter with HI-14143/50 Probe

The HI-99181 portable pH meter is designed specifically for dermatological and cosmetic research applications, providing accurate and reliable skin and scalp pH measurement. Supplied with the HI-14143/50 flat-tip pH electrode, this compact instrument delivers simultaneous pH and temperature readings with high precision, ideal for evaluating cosmetic and pharmaceutical product compatibility with human skin.

Key Features

Designed for Skin & Scalp Testing: Optimised for non-invasive pH measurement on skin and scalp surfaces to support dermatological studies, cosmetic testing, and product formulation analysis.

Flat-Tip Electrode for Contact Accuracy: The HI-14143/50 electrode features a flat sensing surface with an open junction and viscolene reference electrolyte, ensuring optimal contact and stable pH readings on skin without irritation.

Simple Two-Button Operation: User-friendly design with automatic one- or two-point calibration and a large dual-line LCD display for easy interpretation of pH and temperature values.

Portable and Waterproof: Lightweight IP67-rated casing ensures the meter is both durable and resistant to moisture, ideal for field and clinical environments.

Comprehensive Kit Included: Supplied complete with electrode, calibration buffers, cleaning and disinfection solution, beaker, batteries, and calibration certificates for both meter and probe.

Specialised for Dermatological Research

The HI-99181 provides accurate measurement of the skin’s natural pH balance, typically ranging from pH 4 to 6. This acidic mantle plays a crucial role in defending against microbes and environmental contaminants. The ability to measure and monitor variations in skin pH allows researchers and formulators to assess the efficacy and compatibility of cosmetic and pharmaceutical products.

Using the HI-14143/50 probe with a small drop of water on the skin surface enables precise pH determination without damaging tissue. The low-resistance pH glass ensures rapid response, while the open junction minimises clogging and provides stable measurements even on complex surfaces such as hair-bearing skin.

With its simple calibration process, selectable temperature units, and automatic compensation, the HI-99181 offers reliable, repeatable results that meet the needs of laboratories and research teams investigating cosmetic formulation, dermatological safety, and pH maintenance.
