Description

The HI981037 Skin and Scalp pH Tester is engineered for accurate surface measurements, making it ideal for cosmetic, dermatology, and personal care applications. Its flat-tip electrode with open junction allows precise contact with skin or scalp, while single-use pH 4 and 7 buffer sachets ensure reliable calibration every time. The tester displays measurement readings, stability, and calibration tags clearly on a large LCD screen.

Designed for convenience and durability, the tester includes automatic calibration, probe diagnostic alerts during calibration, and a low-battery indicator. The automatic shut-off can be set to 8 or 60 minutes, or disabled entirely, and the CR2032 lithium battery provides up to 1000 hours of continuous use. Proper storage using the included solution ensures long-term electrode performance.

Features

  • Flat-tip pH Electrode: Open junction designed for accurate surface measurements on skin and scalp.
  • Automatic Calibration: One or two-point calibration with buffer recognition and display of used buffer values.
  • Large LCD Display: Shows measurement reading, stability indicator, low battery, and calibration tags.
  • Stability Indicator: Hourglass icon displayed until reading stabilizes for reliable measurement.
  • Automatic Shut-Off: User-selectable 8 min or 60 min, or disabled to conserve battery life.
  • Probe Diagnostic: Error message during calibration alerts when the probe requires cleaning.
  • Low Battery Indicator: Displays when CR2032 battery power is running low; battery lasts ~1000 hours.
  • Single-Use Buffers: pH 4 and 7 sachets ensure fresh calibration every time.
  • Storage Solution: Maintains electrode hydration and prevents organic growth for long-term accuracy.
