Precautions and ordering guide for online dissolved oxygen analyzers

Thread Content

Precautions and ordering guidelines for online dissolved oxygen analyzers: Polarization must be completed before the first measurement, and two hours are required after power is applied; 20 minutes are needed when starting up the device so that the probe can adapt to the ambient temperature. The probe must never be exposed directly to sunlight; if it is necessary to do so, prepare a container with clean water, immerse the probe in it, and try to avoid direct sunlight as much as possible. The bracket that holds the probe must be stable and not disturbed by wastewater. Operators must not change the instrument parameters without permission, and must not expose the dissolved oxygen meter above the water surface. Report any issues promptly if they are discovered. Ordering guide for online dissolved oxygen analyzers: 1. It is necessary to specify whether the electrode used is of the polarographic type or the equilibrium type. 2. The length of the electrode cable is specified as 5m by default. 3. Installation method of electrodes and secondary instruments.
