One-, two-, or three-point calibration automatically recognizes buffer solutions (buffer solutions sold separately). The RENEW feature alerts you when it"s time to replace the pH electrode, while the CAL alert tells you when it"s time to recalibrate the meter.Built-In Intelligence A built-in smart chip offers memory recording of 15 settings, allowing you to compare readings over time. The ExStik lets you know when the meter needs recalibration and when it"s time to replace your pH electrode, so you can reuse it repeatedly with confidence. The smart chip also features automatic temperature compensation, auto power-off, and low-battery indication. A display indicates when the reading is stabilized.Accurately Measures pH And Temperature The ExStik can detect any level on the pH scale with a resolution of 0.01pH and an accuracy +/-0.01pH. The meter also measures temperatures from 23 to 194 degrees Fahrenheit (-5 to 90 degrees Celsius) with an accuracy of +/-1.8 degrees Fahrenheit. By using fresh reference solution, the ExStik achieves continuously dependable results. Optional Accessories To Customize Your Meter To maximize your use of the ExStik PH110, interchangeable probes are available for chlorine and ORP (CL205 and RE305 sold separately).
