Portable dissolved oxygen analyzer for water quality monitoring

Portable dissolved oxygen analyzer for water quality monitoringTHRO2000A digital dissolved oxygen analyzer based on the principle of polar method measurement, capable of precise measurement

The sample contains microgram level dissolved oxygen and also has the function of measuring gas oxygen. Due to the use of digital oxygen sensors

It is not easily affected by external interference during the process and can be widely used in fields such as electricity, petrochemicals, steel, water quality testing, etc.

Portable dissolved oxygen analyzer for water quality monitoringWorking principle of THRO2000

The sensor adopts the principle of polar method measurement and coated oxygen electrode for oxygen measurement（ClarkElectrode). Oxygen molecules enter through the membrane

Immerse in electrolyte at a certain polarization voltage（0.6~0.7V）Oxygen is reduced and generates an electric current.

The current size is proportional to the oxygen concentration, and the current is sampled by precision resistors and operational amplifiers in the hardware circuit

Stable, then sampled by an analog-to-digital converter and sent toCPUThe current data is then processed through atmospheric pressure and temperature

Derive the final oxygen concentration data after parameter compensation, convert it into a digital signal, and transmit it to the host

Display through LCD panel.
