Handheld pH meter ORION STAR™ A111

Take simple, routine pH, mV and temperature measurements with the Thermo Scientific™ Orion™ Star A111 pH Benchtop Meter, an easy-to-use and budget-friendly instrument for basic pH analysis in the lab. Perform up to a three point pH calibration with easy recall of calibration points and slope. Quickly navigate setup menus and ensure consistent calibrations using the simple keypad layout and on-screen text prompts. Use the included electrode stand to easily place sensors in samples and simplify storage to minimize breakage. Large, informative screen clearly shows the main information, including pH or mV reading, temperature, meter mode, calibration information and power source. Thermo Scientific™ AUTO-READ™ locks in the stable reading on your screen and ready indicator alerts when readings are stable Meter offers up to three point pH calibration and automatic recognition of USA/NIST and DIN buffers. Use can easily recall calibration slope data for procedure checks. Nonvolatile memory holds up to 50 data points. Included electrode arm and newly designed probe holder make it easier to maintain and place probes into samples. Plug the meter into almost any power outlet with the included universal power adapter or use four AA batteries (sold separately) to run the meter on DC power.
