HANNA HI122-01 Benchtop pH/ORP/Temperature Meter with Calibration Check™ ORP Dual Range: ±999.9 mV/±2000 mV, pH Range: pH -2.00 to 16.00, Temperature Dual Range: -20.0 to 120.0°C/-4.0 to 248.0°F

HI 122 meters offer all the advanced capabilities for accurate pH measurement with the added feature of a built-in printer. Accurate and reproducible pH measurements depend on proper attention to calibration. When it is necessary for the user to measure pH values outside the standard buffers range. The HI 122 benchtop pH meter can offer help in these situations. Equipped with automatic calibration of up to 5 points, these meters allow the user to tailor the calibration window to the appropriate range. Select from among the 7 factory stored values and up to 2 customized values, for specific applications. With Hanna's featured Calibration Check™, calibration information and probe condition are readily observed directly on the display screen, with a %-value indicating the electrode condition and response consistencies. These meters record and store significant data capture including time, date links to readouts and are compliant with GLP. HI 123 can also perform ORP and store data that can be easily downloaded to a PC through an RS232 port and observed with the optional HI 92000 Windows® compatible software.
