The first pH Meters with integrated PC

SCHOTT Instruments introduces the new laboratory measuring instruments ProLab 3000 (2-channel pH and ISE measuring) and ProLab 4000 (additional Conductivity measuring). The adaptable display comprising the Windows comparable menu structure and the mouse handling are the outstanding convenient features.

Operate the new ProLabs like a PC. You have a 300 MHz processor and a storage volume of 32 MB flash and 32 MB RAM. On a brilliant QVGA colour graphic display (320 x 240 pixels) the operation is handled via a Windows comparable menu structure. The display of all measuring values can be configured in the same manner as on a PC. Operate by using the numeric key pad on either of the ProLabs or using an external keyboard or optionally use the mouse, which is part of the scope of delivery.

Mouse and keyboard can be operated at the same time as the USB host interfaces can be extended by a hub. Also memory stick, USB hard disks, printer and barcode readers can be connected without any additional configuration. Besides the USB host both instruments also feature a USB slave and a RS232 interface.

The automatic electrode and user recognition known with former Lab- and ProLab instruments is also installed in the ProLab 3000 and ProLab 4000. When operating ID electrodes their individual data is used for the calculation of the measurement values, regardless of using one electrode on several instruments or several electrodes on one instrument. The automatic user recognition via transponder pendant plus password protection enables access control and allocation of measurement values, calibrations etc. for each user.

ProLab 3000 and 4000 also comprise the other proven features within the Lab family. For example the CalClock (parallel display of sensor evaluation and calibration intervals), Stability Control (rating of measurement values regarding stability) or the choice of 22 pre-set buffers. The calibration is now improved by the VariCal, enabling the usage of further buffers.
