General description

With dual electrode inputs, the Orion 720A+ allows two measurements at the same time, perfect for a busy, multi-user laboratory. The pH autocalibration feature recognizes five pH buffers using built-in buffer/temperature tables. Express concentration results to three significant digits. Full five point concentration calibration with automatic blank correction improves results of low level measurements. User prompting walks you through each meter operation. Store data using the internal datalogger or print, via the RS232 port.
