HI 99181N is a skin pH meter from HANNA®, specifically designed for skin analysis. Essential for labs researching the biological compatibility of cosmetics and pharmaceuticals. HI 99181N provides affordable, fast, simple measurements without compromising precision.
HI 1414D/50 has a special flat tip electrode that permits perfect contact between probe and sample. Equipped with a built-in temperature sensor, meter readings are adjusted for temperature effects. The calibration is automatic at 1 or 2 points, selectable between 2 memorized buffer sets. A features an automatic step-by-step guide to calibration, enhanced with easy to understand messages and symbols.
The reading can be captured on the display with the HOLD feature. The user can select not only the pH calibration buffer set, but also the temperature measurement unit (°C or °F), This laboratory instrument measures in wide pH and temperature ranges, from -2.00 to 16.00 pH, and from -5.0 to 105.0 °C.
Battery life is more than 1500 hours and the percentage of remaining battery life is displayed at startup. HI 99181N turns off automatically after 8 minutes of inactivity.
