pH/MV/TEMP METER GRAPHIC DISPLAY 1CHANNEL

HI 4211 is a single channel, research-grade laboratory pH Bench Meter with a backlit 240 x 320 graphic display and millesimal

measurement 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

displays concurrent measurement readout and logged graph data, calibration information, including buffer values and expiration date.

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.

 

Our exclusive Calibration Check™ diagnostics system keeps the user informed about the quality and condition of the electrode and

buffer groups for calibration. An enhanced warning system, with acoustic signals, is in place to alert the user when a measurement is

outside of the calibration range. This system will also remind the user when a new calibration is due, or when the wrong buffer is being

used during calibration.

 

This unit can also be designated with a unique ID number. The user can obtain on-board contextual help from any mode simply by

pressing the HELP menu. All features are available in English, Italian, French and Spanish. The user may also connect to a PC via the

opto-isolated USB and RS232 ports and utilize the HI 92000 software Window® compatible software.
