1 Overview
The Oxi 3310 compact precision dissolved oxygen (D.O.) meter
enables you to perform D.O. measurements quickly and reliably.
The Oxi 3310 provides the maximum degree of operating comfort, reli-
ability and measuring certainty for all applications.
The proven OxiCal calibration procedure supports you in your work
with the D.O. meter.
The USB interface can be used for data transmission to a PC and for
software updates of the meter.

Caution
Only connect D.O. sensors to the meter that cannot return any
voltages or currents that are not allowed (> SELV and > current
circuit with current limiting).
Almost all customary D.O. sensors fulfill these conditions.
