High-precision, low-maintenance fluorescent (optical) dissolved oxygen meter 'LDO2'
HACH products
Industrial DO meter with fluorescent (optical) method for continuous measurement, easy maintenance, and stable measurement over long periods.
The "LDO2" fluorescent dissolved oxygen meter is a dissolved oxygen meter that employs an optical sensor, achieving both stability and reliability through an innovative measurement principle that differs from traditional membrane types. By controlling the emission of blue and red LEDs inside the detector, it accurately detects fluorescent reactions corresponding to oxygen concentration. Optical zero adjustment is also performed automatically, ensuring stable measurements over long periods. 【Features】 ■ No membrane required: Structure without electrolyte or anodes/cathodes eliminates the need for part replacement. ■ Significantly reduces maintenance effort: Only requires sensor cap replacement every two years. ■ Long-term stability maintained through optical zero adjustment. ■ Minimal impact from interfering substances or flow rate changes, allowing stable operation in a wide range of water quality environments. ■ Simultaneous measurement with 2 channels: Two detectors can be connected to the SC4500 converter. *For more details, please refer to the PDF document or feel free to contact us.
