Hash portable dissolved oxygen analyzer HQ30d wholesale, HQ30D fluorescence LDO dissolved oxygen analyzer

Advantages of Hash HQ30D dissolved oxygen analyzer:
(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 typically undergo a polarization process 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 to calibrate it during use and can directly measure the dissolved oxygen concentration. Traditional dissolved oxygen meters usually have calibration steps when in use, and only after calibration is passed can dissolved oxygen be measured.
(3) Low maintenance: The LDO probe equipped with HQ30d is a membrane free probe, which does not require replacement of membrane components or filling of electrolyte. The maintenance amount is greatly reduced, saving time and reducing user maintenance costs.
(4) Strong anti-interference ability: The LDO probe equipped with HQ30d is a membrane free probe, so it is not affected by typical chemical substances in wastewater.
(5) Durable fluorescent cap: The HQ30d fluorescent cap can maintain its accuracy and is easy to clean even if it is scratched or partially contaminated.

Hash HQ30D dissolved oxygen analyzer

Measurement method:
Portable dissolved oxygen analyzer: a new technology for measuring dissolved oxygen - fluorescence measurement of dissolved oxygen

The LDO dissolved oxygen sensor of the HACH portable dissolved oxygen analyzer is covered with a layer of fluorescent material. When the blue light emitted by the LED light source illuminates the fluorescent material on the sensor surface, the fluorescent material is excited and releases red light. The period from emitting blue light to emitting red light is recorded. The higher the oxygen concentration in water, the shorter the time for releasing red light. Establish a correlation between the release time of red light and dissolved oxygen concentration. The 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.
