Managing Trace-Level Dissolved Oxygen
Dissolved Oxygen Overview Trace levels of dissolved oxygen can be measured at parts per billion (ppb) or micrograms per litre (µg/L) using a dissolved oxygen meter . Online measurement technology in this concentration range is usually different from that for parts per million (ppm) measurements, One of the problems of dissolved oxygen is that it can cause pitting and damage to various components of boiler systems, such as condensate lines and economizers. Thus, one of the primary uses of a dissolved oxygen monitor is for boiler water for corrosion control. Optimizing Dissolved Oxygen Measurement Device Sensitivity When you’re installing a new membrane module on your dissolved oxygen analyzer, it usually takes the unit about 24-48 hours to reach peak accuracy and sensitivity. Keep in mind that this is in ideal, low-oxygen conditions Dissolved oxygen sensors that have been in service for a period of time will respond much quicker than a newly-installed sensor.
