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-1414D/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-1414D/50 pH/temperature probe with flat tip, 50mm-long body, DIN Connector and 1m cable
