These portable pH/mV meters feature Thermo Scientific Orion quality. The economical A121 meter features a large informative screen that lets you simultaneously view the pH or mV reading, temperature, battery life and calibration status. Simple button layout and onscreen messages make calibration and setup easy and fast.

Measure in either Continuous mode or AUTO-READ™ mode that locks in the stable reading on your screen. You can record up to 50 data points. When recording data points in AUTO-READ mode, measurements are automatically stored whenever the "READY" appears.

Three-point calibration is simplified with automatic buffer recognition of USA/NIST and DIN buffers. When taking readings, the meter displays the buffer values that were used to calibrate. The most recent calibration slope is also stored for procedure checks. Meter runs for up to 2,000 hours on included 4 AA batteries, or purchase optional AC power adapter separately. 3-year meter warranty for both meters.

Meter includes: four AA batteries, manual, and CD with user reference guide. Order pH electrode separately.
