HI-99181 Skin pH Meter information

Hanna's extended description

Researchers monitoring the compatibility between skin and cosmetics or pharmaceuticals use pH as essential marker of compatibility.

The skin mantle has an acidic pH, ranging from pH 4 to 6. The acidic pH is a deterrent toward harmful microbes, pollution, and toxins. Age, generics, sweat, and moisture can alter the pH of skin. Products are constantly created to restore the pH balance of skin and a reliable pH measurement of skin provides the scientific metrics.

The HI-99181 portable pH meter together with a HI-14143/50 combination pH electrode (when immersed in a drop of water on the skin surface), can determine the pH of the skin with high accuracy.

The HI-99181 features two button operation and is simple to use. The HI-99181 has a waterproof and compact casing, large dual-line display, and automatic pH calibration at one or two points.

Each meter is supplied complete with:

  • HI-14143/50 pH/temperature probe with flat tip, 50mm-long body, DIN Connector and 1m cable
  • pH 4.01 & 7.01 buffer sachets
  • HI-700621 cleaning and disinfection solution for skin residual (1 sachet)
  • 100 mL beaker
  • Alkaline batteries 1.5V AAA x 3
  • Rugged carrying case
  • Calibration certificate for meter
  • Calibration certificate for probe
  • Instruction manual
  • Main features:

  • Simultaneous pH and temperature measurements on a large dual-line LCD display
  • Automatic pH calibration at one or two points within two memorised buffer sets (standard and NIST)
  • Selectable temperature unit (°C)
  • Electrode condition indicator
  • mV of pH measurement for electrode check
  • HI-14143/50 dedicated pH with integral temperature sensor
  • Probe quick connect system
  • Battery life indication and low battery detection
  • Keystroke confirmation tone
  • Auto-off function
  • Waterproof casing IP67

  • Battery powered – Allows use away from a power source. Batteries are included with all battery operated products.
