Lovibond SD 400 Optical Dissolved Oxygen meter

Lovibond has two variations in this range fo waterproof handheld meters:

SD 300 Series

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

SD 300

Additional Display for pH Electrode - pH Calibration Automatic Buffer Recognition. Permissible electrodes data: Asymmetry: ± 55 mV / Slope: 45 ... 62 mV/pH The condition of pH Electrode is checked at each calibration.  1, 2 or 3 point calibration with Lovibond® Standard Buffer, DIN 19266 Buffer or any manually entered Buffer values.

Redox Measurement (ORP) 2 options:

• “mV” Standard Redox or mV measurement
• "mVH” Conversion to hydrogen systems according to DIN38404 Part 66

rH Measurement -The rH value is calculated from a measured Redox value and a manual input pH value

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)
