- Specifications
HK-8060 Online Luminescent Dissolved Oxygen Analyzer, a high performance online measurement instrument, is composed of transmitter and sensor. The monitor is based on fluorescence quenching to determine the oxygen content in water. Measurement signal，taking into account the water temperature and pressure, is calculated by sensor detecting and analyzing continuously. Digital communication provides fault-free communication between sensor and transmitter, which can avoid common electromagnetic noise interference in field.
Features
◆Adopt fluorescence principle which does not require frequent calibration.
◆ No drift and free maintenance.
◆There is no strict requirement for sample.
◆It has strong anti-interference ability and it is not polluted by hydrogen sulfide, heavy metals, oil and gaseous chemicals.
◆ Fast response of measurement time.
Applications
◆ Measure and control the oxygen in aeration tank during sewage treatment
◆ Monitor the water environment (river, lake, seawater .etc)
◆ Measure and control the oxygen content in public water source
◆ Measure and control the oxygen content in fishpond
◆ Measure and control the oxygen content in drinking water
◆ Power, food, chemical and other industries
