HACH LDO portable dissolved oxygen analyzer from the United States

Introduction to HACH LDO portable dissolved oxygen analyzer in the United States:

The portable dissolved oxygen analyzer is suitable for measuring the concentration or saturation of oxygen dissolved in water.

LDO ™ The portable dissolved oxygen meter and LDOTM portable dissolved oxygen meter are two portable instruments developed by Hash Company using new technology, 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.

In terms of measuring dissolved oxygen technology, portable dissolved oxygen meters with LDO probes are more effective compared to traditional dissolved oxygen meters based on current or spectroscopy,

Has many advantages:

(1) No need for dilution: When measuring dissolved oxygen, the LDO dissolved oxygen analyzer probe does not require dilution time. Traditional dissolved oxygen probes usually undergo a dissolution process before use.
(2) No calibration required: The LDO dissolved oxygen analyzer probe 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 dissolved oxygen analyzer probe is a membraneless probe that 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 is a membraneless probe, so it is not affected by the interference of chemical substances in typical wastewater.
(5) Durable fluorescent cap: The fluorescent cap can maintain its accuracy even when scratched or partially contaminated, and is easy to clean.
