Take simple, routine pH, mV, and temperature measurements with the Orion™ Star™ A111 pH Benchtop Meter, an easy-to-use and budget-friendly instrument for basic pH analysis in the laboratory.

Large, informative screen clearly shows the main information, including pH or mV reading, temperature, meter mode, calibration information, and power source. 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.

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.
