Portable Waterproof LDO Oxymeter with Optical Probe

Portable waterproof LDO meter with optical O2/°C probe

LDO principle (Luminescent Dissolved Oxygen): based on the quenching of luminescence of an oxygen-sensitive luminophore.

Optical probe: Inert platinum luminophore activated by a blue LED (excitation), red LED as reference, measurement without oxygen consumption, thus no interference and no need for frequent recalibration.

Technical specifications

- Measurement ranges:

• • % O₂ saturation

  • Concentration in mg/L

- Automatic compensations:

• Temperature (one-point calibration)

• Salinity (for seawater measurements)

• Altitude (automatic compensation)

• Display: large backlit matrix screen with multifunction virtual keys and contextual help menu.

• Alarms: visual alert in case of calibration delay (programmable interval).

• Advanced functions: integrated algorithms for BOD (Biochemical Oxygen Demand), OUR (Oxygen Uptake Rate) and SOUR (Specific Oxygen Uptake Rate).

Advantages

- Robustness: IP67 housing designed for field environments.

- Accuracy and reliability: optical technology without drift, no membranes to replace.

- Ease of use: Quick DIN connection, intuitive interface with help menu.

- Versatility: usable in laboratory, aquaculture, water treatment, environment.

- Reduced maintenance: no electrolyte solution or cathode/anode to maintain.

Typical applications

- Aquaculture: monitoring dissolved oxygen for fish health.

- Water treatment: quality control and process optimization.

- Environmental laboratories: BOD measurements and pollution monitoring.

- Food industry: control of water used in processes.
