These portable pH/mV meters feature Thermo Scientific Orion quality. The advanced A221 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.

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.

Unit offers five-point calibration. Calibration date, values and slopes are stored in the Calibration Log for later review. Download up to 1,000 data points with time/date stamp to your computer or printer using RS-232 or USB. Selectable visual and audible alarms signal measurements outside your set points. The A221 has a backlit display that shows the time and date. Plain-language screen prompts are available in 6 languages.

Meter kit includes: four AA batteries, pH electrode, pH 4, 7 and 10 buffers, storage solution, cleaning solution, protective armor with electrode holder, hard carrying case, manual and CD with user reference guide.
