AL4050 Digital Dissolved Oxygen On-line Sensor

The dissolved oxygen concentration is detected based on the fluorescence quenching method, without the need to replace the dissolved oxygen diaphragm and electrolyte, and the response time is fast, and the measurement is not affected by particulate matter and flow rate. The housing is made of corrosion-resistant stainless steel and has an IP68 waterproof rating. It is suitable for on-line monitoring of dissolved oxygen content in drinking water, surface water, aquaculture, biotechnology, food and beverage, and water treatment. It has RS485 communication interface and standard MODBUS protocol, which is easy to integrate and network. WQS-SUTIE upper computer analysis software is included, which can be used for parameter setting, calibration, measurement and fault diagnosis of the product.

Range calibration is carried out directly in air, without the need to configure standard liquid;

Maintenance-free, no need to replace dissolved oxygen diaphragm and electrolyte;

Particulate matter and flow velocity changes have no effect on the measured values;

Platinum resistance temperature compensation, temperature measurement accuracy up to ¡À0.1¡ãC;

Built-in fault self-diagnosis function to ensure accurate data;

Factory pre-calibration, factory calibration parameters can be restored at any time;

The sensor interface has the function of misconnection and reverse connection protection;
