Why Skin pH Matters

Skin pH is a critical indicator of skin health, barrier function, and product compatibility. The skin's natural pH typically ranges from 4.5 to 5.5 (slightly acidic), which helps maintain the protective acid mantle, prevent bacterial growth, and support optimal barrier function. The Hanna HI981037 Skin & Scalp pH Tester provides accurate, non-invasive pH measurement designed specifically for dermatology, cosmetic formulation, and skincare applications.

Understanding Skin pH

The skin's acid mantle is a thin, protective layer on the skin's surface that plays crucial roles in:

• Barrier protection - Prevents moisture loss and protects against environmental damage
• Antimicrobial defense - Acidic pH inhibits harmful bacteria and fungi
• Enzyme activity - Optimal pH supports natural exfoliation and renewal processes
• Product efficacy - pH affects how skincare ingredients perform and absorb

Disrupted skin pH is associated with conditions like eczema, acne, rosacea, and premature aging. Accurate pH measurement helps professionals assess skin health, evaluate product effects, and develop targeted treatment protocols.

Meet the Hanna HI981037

The HI981037 is a specialized pH tester engineered specifically for skin and scalp measurement. Unlike general-purpose pH meters, this instrument features a flat glass tip for direct surface contact, an open junction design to prevent clogging from skin residue, and a compact form factor for clinical and field use.

Designed for Skin Measurement

The HI981037's unique probe design addresses the specific challenges of measuring pH on skin surfaces. The flat glass tip ensures consistent contact with skin, while the open junction prevents clogging from oils, sebum, and cosmetic residues that would compromise standard pH electrodes.

Key Features & Benefits

Specialized Probe Design

The flat glass tip allows direct measurement on skin and scalp surfaces without sample preparation. The open junction design resists clogging from skin oils and residues, while the glass body is chemically resistant and easy to clean and disinfect between patients or test subjects.

High Accuracy

With ±0.05 pH accuracy across the critical 0-12 pH range, the HI981037 provides reliable data for clinical assessment, product testing, and research applications. The 0.01 pH resolution captures subtle pH changes.

Automatic Temperature Compensation (ATC)

pH readings are temperature-dependent. The HI981037 automatically compensates for temperature variations from 0-50°C, ensuring accurate measurements regardless of skin temperature or ambient conditions.

User-Friendly Operation

Single-button operation makes the HI981037 simple to use in clinical settings. The large LCD display shows pH readings clearly, while the onscreen stability indicator confirms when readings have stabilized for recording.

Pocket-Sized Portability

At just 48g (1.7 oz) and measuring 124mm long, the HI981037 fits easily in a lab coat pocket. The compact design is perfect for clinical rounds, field studies, or mobile cosmetic consultations.

Long Battery Life

The CR2032 lithium-ion battery provides approximately 800 hours of continuous use. Selectable auto-off options (8 minutes, 60 minutes, or disabled) help conserve battery life based on your workflow.
