  • Page 8: Presentation

    See figure 1 at the beginning of this manual he TX/OX2000(+) is a stand-alone, “ pocket ” oxygenometer or toximeter intended for the (continuous) detection of toxic or oxygen gases or vapours. The TX/OX2000(+) is equipped with a plug-in sensor which can be accessed after unscrewing the sensor cap on the top of the instrument.
