-Introduction:

The all-new generation of hash LDO^®II dissolved oxygen sensor, based on the principle of fluorescence quenching for the determination of dissolved oxygen. Unlike traditional current and polarographic dissolved oxygen sensors, fluorescence dissolved oxygen sensors do not use membranes or electrolytes, have low maintenance rates, and are easy to operate; At the same time, the fluorescence method dissolved oxygen sensor does not consume oxygen, and there are no requirements for water sample flow rate and stirring during measurement. It is also not affected by substances such as sulfides, making the determination of dissolved oxygen simpler.

-Working principle:

LDO^®The dissolved oxygen sensor II is based on the principle of fluorescence quenching. Blue light shining on a fluorescent substance excites red light. Since oxygen molecules can take away energy, the time and intensity of the excited red light are inversely proportional to the concentration of oxygen molecules. The dissolved oxygen analyzer can calculate the concentration of oxygen molecules by measuring the phase difference between the excited red light and the reference light, and comparing it with the internal calibration value.

-Typical applications:

LDO^®The II dissolved oxygen sensor is suitable for measuring dissolved oxygen in industries such as sewage, industrial water, and drinking water.

-Features and advantages:

No calibration required
Hash LDO^®The dissolved oxygen sensor II has been calibrated before leaving the factory and can be used immediately without calibration. The fluorescent cap has a lifespan of up to two years.

No need to replace the membrane
Using Hash's breakthrough fluorescence technology, this dissolved oxygen sensor requires minimal maintenance as there is no need to replace the membrane, replenish electrolyte solution, or polish and clean the anode and cathode.

● Service without omission
The dissolved oxygen sensor has a customizable cleaning service prompt function, which automatically triggers a service prompt message during the dissolved oxygen measurement process to remind users to clean the dissolved oxygen sensor and ensure that the cleaning cycle is not missed.

● No drift
The groundbreaking 3D calibration technology enables HashLDO^®The dissolved oxygen sensor has been accurately calibrated before leaving the factory, making the measurement of dissolved oxygen more accurate than ever before!

● More sturdy
Innovative Hash LDO^®The housing of the dissolved oxygen sensor II is sealed with O-ring and ultrasonic dual sealing while using new materials, which is corrosion-resistant and water-resistant, improving durability. At the same time, the probe size has been reduced, making the measurement of dissolved oxygen easier and more suitable for harsh environments such as sewage and industrial wastewater.
