pH meter precision stick model PH-110

Highly accurate, digital pH meter, professional use model. With a refillable measuring electrode that calibrates the electrode and ensures an accurate result. Features: built-in thermometer (°C / °F); automatic temperature corrections (ATC): -5°C to +90°C / 25°F to 194°F; Digital display of pH and temperature with stabilization reading; easy 2 or 3 point calibration with automatic detection of the calibration fluid; refillable flat electrode, also for measuring the pH of solids and semi-solids (skin, meat, cheese, etc.). Filling the electrode significantly extends its life. The electrode should only be replaced if damaged. Measurement is also possible for low liquid levels and also for surfaces. RENEW function: warns when the electrode needs to be replaced. CAL function: warns when the electrode needs to be calibrated. MEMORY for 15 readings: pH and temperature; HOLD function; measuring scale pH: 0.00-14.00 pH; temperature: -5 to +90°C / 25 to 194°F; accuracy: ± 0.01, ± 1°C; IP67 or waterproof, automatic shutdown after 10 minutes, electrode protective cover, replacement membrane, instructions, 4 Li-ion batteries CR2032, Warranty: 1 year meter, 6 months electrode. What is pH? pH is a measurement of the concentration of free hydrogen ions in a liquid. The pH of pure water is 7. Liquids with a higher concentration of hydrogen ions than water are acids and the pH value is less than 7. Liquids with a lower concentration of hydrogen ions are more alkaline and the pH value is greater than 7. The calculated pH value is 1-14..
