This LCD control panel works with Fibox 3, Fibox 3-Trace, Microx TX3 and Microx TX3-trace instruments. Its graphical LCD (display) with background illumination allows full control of the instrument. The LCD control panel allows both easy calibration and measurement. All operations are controlled just by four buttons. The easy menu structure makes the system self-explanatory. The integrated data-logger stores up to 26000 measurement values. This option extends the single channed oxygen meter to stand-alone measurement system with built-in data acquisition system. For read-out of the stored vales a PC is necessary.
