dissolved oxygen and ammonia sensor

Hydrolab HL4 Multiparameter Sonde - OTT Hydromet

Ammonia has two forms - the ammonium ion, and the unionized, dissolved ammonia gas (NH3). The form depends on pH, with ammonium predominating when the pH is below , and ammonia redominating above pH Total ammonia is the sum of ammonium and ammonia concentrations. Ammonia is very toxic to water life, ammonium is less toxic.

Dissolved Oxygen Monitor | Water Quality Monitor

As oxygen diffuses into the active sensor material it interacts with the light absorbing compound and interferes with the emission reaction. This interaction, called quenching, causes the light absorbing material to release energy in a form other than light. The degree of quenching is proportional to the concentration of dissolved oxygen. The quenching reaction is reversible, which allows this ...

Beyond signal quality: The value of unmaintained pH ...

· The sensor types are ion-selective pH, optical dissolved oxygen (DO), and oxidation-reduction potential (ORP) with platinum electrode. We created soft sensors using engineered features: ammonium valley for pH, oxidation ramp for DO, and nitrite ramp for the ORP. Four soft sensors based on unmaintained pH sensors correctly identified the ...

Comparison of Dissolved Oxygen Sensors - pHionics

· Optical Dissolved Oxygen Sensors (ODOs) Optical (also known as luminescent) sensors utilize light to measure dissolved oxygen concentration. Like the electrochemical method, optical ODOs have an oxygen-permeable material at the tip of the electrode. An oxygen-sensitive, luminescent dye makes up the second layer. The dye is exposed to a specific wavelength of light in the sensor and the ...
