Product Overview:
Hash dissolved oxygen analyzer HQ30dSuitable for measuring the concentration or saturation of oxygen dissolved in water.LDO™ The portable dissolved oxygen analyzer is developed by Hash Company using new dissolved oxygen measurement technology and is suitable for laboratory and field testing.
working principle:
LDO™ The portable dissolved oxygen analyzer adopts a new dissolved oxygen measurement technology - fluorescence method measurement.
HACH LDO™ The dissolved oxygen sensor of the portable dissolved oxygen analyzer is covered with a layer of fluorescent substanceLEDWhen the blue light emitted by the light source shines on the fluorescent substance on the surface of the dissolved oxygen meter sensor, the fluorescent substance is excited and releases red light. The higher the concentration of dissolved oxygen, the shorter the time from emitting blue light to releasing red light. The dissolved oxygen meter will record this time and establish a correlation between the red light release time and the dissolved oxygen concentration,LDO™ The dissolved oxygen meter calculates the dissolved oxygen concentration by measuring the release time of red light and directly displays the result on the screen.
Application industry:
Hash dissolved oxygen analyzer HQ30dSuitable for laboratory and field testing. If you want to achieve real-time monitoring, you can choose Italy's Pi MagneticOnline dissolved oxygen analyzer OD7685Easy to operate and cost-effective.
Instrument features:
LDO™ The portable dissolved oxygen analyzer adopts high-precision fluorescence measurement method, which has many advantages compared with traditional dissolved oxygen analyzers based on current or polarography:
1)No polarization required: Traditional dissolved oxygen analyzer probes usually undergo polarization before use, whileLDO™ The dissolved oxygen analyzer probe does not require polarization.
2)No calibration required:LDO™ The dissolved oxygen analyzer probe has been calibrated before leaving the factory, so users do not need to calibrate when using the dissolved oxygen analyzer and can directly measure the 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)Strong anti-interference ability:LDO™ The probe of the dissolved oxygen meter is a membraneless probe, so it is not affected by the interference of chemical substances in the wastewater, and the measurement results are more accurate.
4)Low maintenance volume:LDO™ The portable dissolved oxygen analyzer does not require replacement of membrane components or filling of electrolyte, greatly reducing maintenance costs and saving time for users.
5)Durable fluorescent cap: The fluorescent cap of the dissolved oxygen meter probe can maintain its accuracy even when scratched or partially contaminated, making it easy to clean.
