Description
Professional pH Bench Meter with Built-in Printer
Hanna Instruments HI 122
Description:
HI 122 and HI 123 are strong additions to the HANNA® family of professional pH meters. These
meters offer all the advanced capabilities for accurate pH measurement with the added feature of a
built-in printer.
Along with sophisticated functions such as millesimal resolution and automatic temperature
compensation, HI 122 and HI 123 are provided with our signature Calibration Check™ system that
evaluates the electrode condition and function in relation to calibration. Together with the ability to
customize a calibration curve with up to 5 points (selected from 7 stored plus 2 custom values), these
products are suitable for any laboratory application. Such flexibility makes these meters ideal
for both extreme acidic pH, and with very alkaline pH applications as well as precise pH neutral
requirements.
Both meters adhere to Good Laboratory Practices and store data and measurements for each
calibration, with options to print directly or download to a PC through the RS232 port.
HI 123 can also measure specific ions (ISE) directly in ppm. Calibration is simple, in 1 or 2 points
from among 5 standard memorized buffers. Chose from our newly developed line of specific ion
sensors for your specific application.
