Features & Applications:

This Hanna research grade laboratory pH / ORP bench meter has a backlit 240 x 320 dot-matrix color screen and millesimal measuring resolution. Features include auto-logging and real-time graphic displays, auto-end point mode and a fully customizable SETUP button. This unit allows for automatic (ATC) or manual (MTC) temperature compensation. For accountability, on-screen GLP data capture contains calibration information, including buffer values and expiration date, concurrent with measurement readings and logged graph data. With the option to choose up to 5 calibration points for pH - selected from a list of 5 custom and 8 memorized buffers - the system can be fitted to any desired measuring range.

Hanna's exclusive Calibration Check™ diagnostics system determines the quality and condition of the electrode and buffer groups during calibration, and keeps you informed. An enhanced warning system, with acoustic signals, alerts the user when measuring is outside of the calibration range. This system also reminds the user when a new calibration is due, or when the wrong buffer is being employed during calibration. This unit can be given a unique ID number.
