overview
This Benchtop Dissolved Oxygen Controller quantifies oxygen dissolved in liquid solutions. Air holds a steady oxygen fraction of around 20.9%, and oxygen will dissolve into water once the two make contact.
Many conditions determine how much oxygen water can retain: sufficient time and agitation for full saturation, water temperature, ambient air pressure, salinity, as well as substances that consume oxygen in the water. Given its significance to a wide range of biochemical reactions, testing the real dissolved oxygen content of water samples is indispensable.
Notes
1.Take care not to bump the electrode head while in use, as 2.this may interfere with readings.
Keep the unit in a dry place out of light. Do not expose it to damp conditions or direct solar radiation.
3.For long-term storage, check the instrument's working status periodically and recalibrate it on schedule to maintain accurate detection data.
4.Abide by applicable laws, rules and standards throughout operation to ensure the measurements are compliant and precise.
5.Factors including temperature, pH and turbidity of water samples may affect dissolved oxygen tests, so take proper measures to reduce errors. Regular upkeep is also required to keep the instrument stable and accurate over time.
Feature
This device is equipped with a dot-matrix backlight display. It supports automatic temperature compensation and offers rapid response. The bundled coated galvanic cell DO electrode ensures consistent performance during prolonged testing.
