Dissolved Oxygen Measurement
Dissolved oxygen (DO) is the oxygen held in water, read in ppm (mg/L) or as % saturation. Hintron monitors read it continuously, with temperature compensation and alarms for the limits you set.

Method
How it is measured
01
Calibrate
Set the zero in an oxygen-free solution and the span in air-saturated water.
02
Measure
The DO probe gives a signal proportional to the oxygen that passes through its membrane.
03
Compensate
The reading is corrected for water temperature, which changes how much oxygen water can hold.

Questions
Frequently asked
What is the difference between ppm and % saturation?
ppm (mg/L) is the amount of oxygen in the water. % saturation compares it with the most that water can hold at that temperature and pressure. The monitor shows either; choose the unit from the keys.
Why does dissolved oxygen need temperature compensation?
Cold water holds more oxygen than warm water, and the probe itself responds to temperature. The monitor reads a temperature probe and corrects the DO reading automatically.
Can dissolved oxygen be monitored continuously?
Yes. The Hintron HTN-MU003 online monitor shows DO live alongside pH, temperature and conductivity, with high and low set points and a built-in buzzer for each parameter.
Application support
Need to monitor dissolved oxygen?
Describe the sample, the point you want to monitor and the quantity. A specialist replies with a recommendation and a quotation.
