Product details
Hash portable dissolved oxygen analyzer LDO TM
The portable dissolved oxygen analyzer is suitable for measuring the concentration or saturation of oxygen dissolved in water. LDO ™ The portable dissolved oxygen analyzer is developed by Hash Company using technology and is suitable for both laboratory and field testing. Portable HQ30D is available, while laboratory model HQ440D is available.
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.
