LDO® II 溶解氧探头

2LDO® II dissolved oxygen probe

-Introducing a new generation of hash LDO probes to measure dissolved oxygen, everything becomes easier. -Working principle: Fluorescence method-Typical application-Sewage, industrial water, drinking water With the breakthrough fluorescent technology of Hach Company, the probe basically needs no maintenance, because there is no need to replace the diaphragm, no electrolyte solution is added, and there is no need to polish the anode and cathode. No missing service cleaning service prompts can be customized, when the service prompt message is automatically triggered, then it will never operate

Product description
Technical indicators
-Introduction
 
A new generation of hash LDO probes measure dissolved oxygen, everything becomes easier.
 
 
 
-Working principle: fluorescence method
 
 
 
-Typical applications-sewage, industrial water, drinking water
 
 
 
-Features and benefits
 
No calibration required
 
Hach LDO® II probes are available out of the box, no calibration is required, and the lifetime of the fluorescent cap is up to two years
 
No need to change the diaphragm
 
With Hach ’s breakthrough fluorescence technology, the probe is basically maintenance-free, because there is no need to replace the membrane, no electrolyte solution, and no need to polish the anode and cathode.
 
No missing service
 
The cleaning service prompt can be customized, and the service prompt message is automatically triggered at that time, so that the probe cleaning cycle will never be missed.
 
No drift
 
The epoch-making 3D calibration technology makes the Hach LDO II probe accurate calibration before leaving the factory, and the measurement is more accurate than ever!
 
Stronger
 
The innovative Hach LDO® II housing uses new materials and double seals with O-rings and ultrasonics to improve durability. At the same time reduce the size, making it easier to operate
