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.)

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
