Specification :

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 Checkâ„¢ 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.
