Details of Hash Proxy HQ30d Portable Dissolved Oxygen Analyzer:

Hash proxy HQ30d portable dissolved oxygen analyzer

The portable dissolved oxygen analyzer is suitable for measuring the concentration or saturation of oxygen dissolved in water. The HQ30D portable dissolved oxygen analyzer is developed by Hash Company using new technology and is suitable for laboratory and field testing. Portable dissolved oxygen analyzer: a new technology for dissolved oxygen measurement - fluorescence measurement of dissolved oxygen. The LDO dissolved oxygen sensor of HACH's portable dissolved oxygen analyzer is covered with a layer of fluorescent material. When the blue light emitted by the LED light source shines on the fluorescent material on the surface of the sensor, the fluorescent material is excited and releases red light. The time from emitting blue light to emitting red light is recorded. The higher the oxygen concentration in water, the shorter the time it takes to release red light. Establishing a correlation between the release time of red light and dissolved oxygen concentration, a portable dissolved oxygen analyzer calculates the dissolved oxygen concentration by measuring the release time of red light, and then directly displays the dissolved oxygen concentration on the screen.

Main advantage：

(1) No polarization required: When measuring dissolved oxygen, the LDO dissolved oxygen probe equipped with HQ30d does not require polarization time. Traditional dissolved oxygen probes usually undergo polarization processes before use.
(2) No calibration required: The LDO dissolved oxygen probe equipped with HQ30d has been calibrated before leaving the factory, so users do not need calibration when using it and can directly measure dissolved oxygen concentration. Traditional dissolved oxygen meters usually have calibration steps when in use, and only after passing the calibration can dissolved oxygen be measured.
(3) Low maintenance: The LDO probe equipped with HQ30d is a membraneless probe, which does not require replacement of membrane components or filling of electrolyte, greatly reducing maintenance costs and saving time for users. ​
(4) Strong anti-interference ability: The LDO probe equipped with HQ30d is a membraneless probe, so it is not affected by typical chemical substances in wastewater.
(5) Durable fluorescent cap: The fluorescent cap equipped with HQ30d can maintain its accuracy even in the event of scratching or partial contamination, and is easy to clean.
