SD 400 Oxi L

Measurement of dissolved oxygen at an advanced level.

The SD 400 Oxi L allows the measurement of dissolved oxygen in a convenient and simple manner. The determination of dissolved oxygen in water is based on optical luminescence technology. This is characterized by fast response time and a particularly low maintenance requirement. Combined with high accuracy, this technology offers great benefits to the user. 

For oxygen measurement by means of luminescence technology, the following advantages are obtained compared to galvanic sensors and Clark sensors:

• High accuracy
• No sample flow is needed
• Low maintenance
• No oxygen consumption in the measuring medium
• No pollution of ambient medium
• Long-life sensor membrane
• Robust measurement even in sulfide-containing samples

Additional features of SD 400 Oxi L

• Waterproof sensor IP 67
• Backlit LCD 
• Internal data storage
• Software for monitoring and storage of data
• Micro USB port
• Comfortable fitting to BOD Karlsruhe NS 19 / 26 (16.4 mm ø and above)

Lovibond has two variations in its range of waterproof handheld meters.  These electrochemical measuring instruments are designed for safety, mobility, and ease of data retention and storage. The data loggers regularly save the collected measurement data which can be transferred to the computer via USB interface (serial or analogue). With the SD 305 series, the instrument is protected with armoring and the electrode holders can be handled comfortably with one hand even under adverse conditions. With its luminescence technology and drift-free optical measurement, the SD 400 Oxi L offers analysis at the highest level with low maintenance requirements.  

SD 300 Series

 These are portable handheld instruments for the determination of pH values. It is reliable, waterproof (IP67), and robust, making it an ideal solution for on-site analysis.  Three different models of this meter for the determination of pH/Redox/Temperature, Conductivity/TDS/Salinity/Temperature, and  Dissolved Oxygen (O₂)/O₂ -Concentration/O₂ -Saturation Temperature.

Key benefits:

• Rugged, water-resistant (IP 67)
• PC interface (USB / serial or analog)
• Automatic buffer detection
• Data logger and alarm function (min./max.)

Available models:

SD 400 Oxi L

 SD 400 Oxi L portable meter combines measurement f dissolved oxygen at an advanced level with low maintenance thanks to state-of-the-art luminescence technology it is suitable for research and teaching, use in sewage and waterworks, and aquaristics.

The electrode of the SD 400 Oxi L is optimized for standard BOD bottles (NS 19/26). The device is therefore ideally suited for standard-compliant BOD determination of the dilution BOD.

Key benefits:

• Luminescence technology
• High accuracy
• Low maintenance
• Drift-free, optical measurement
