Designed to bring simplicity to pH testing of flat surfaces, the HI99181 Skin pH Portable Meter is designed for surface measurements. The specialized HI14143/50 probe features a glass body, flat tip, and open junction making it ideal for the non-destructive pH testing of skin surfaces.

  • ±0.02 pH accuracy
  • Comes with all the necessary solutions and batteries- everything you need to get started measuring right away.
  • Specialized for the direct pH measurement of skin and scalp.

Probe Condition An on-screen indicator provides visual confirmation that your probe is working at its best.

Low Battery Indicator The included batteries provide 1200 hours of continuous use. When the battery level is below 10%, a warning symbol will blink to indicate low battery condition. When low battery power may affect your results, the meter will shut down to avoid erroneous readings caused by low battery level.

Automatic Shut-off The auto-off feature can be set to shut the meter off at 8 or 60 minutes, or it can be disabled so that the meter continuously stays on. The auto-off feature prolongs battery life for peace-of-mind and energy savings if the meter is accidentally left on.

Built to be Durable Designed to withstand the knocks, drops, and spills of real life, the new IP67 body ensures top performance in any environment. These meters are protected against dust and water intrusion from any direction.

Portable Design Made to fit comfortably in your hand for on-the-go testing, the multilevel LCD display provides at-a-glance readings of pH and temperature from any angle and dual button operation streamlines the testing process for any user.

Quick Connect Probe A Quick Connect DIN connector makes attaching and removing the probe simple and easy. The rubber coating protects the cable and provides a water-tight seal without twisting.

Your measurements require detailed attention; so should your electrode. The HI99181 Skin pH Meter features a replaceable probe that has been carefully designed specifically for the pH analysis of skin and scalp surfaces.

Glass Body A glass body is easy to clean, is chemically resistant, and quick to reach thermal equilibrium for a faster, more stable measurement.

Flat Tip The flat tip requires minimal sample immersion, allowing you to measure moist solid samples or small sample volumes.

Open Junction The open junction design reduces clogging from organic materials found in leathers and paper for a more stable pH measurement and reduced maintenance.
