Portable Hand-held Meters with Datalogger

SD 400 Oxi L (Set 3)

Optical determination of dissolved oxygen - precise and fast measurement results

 

Highlights

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

The portable SD 400 Oxi L handheld meter allows the determination of dissolved oxygen using the highly accurate optical luminescence technology. The advantages of optical oxygen determination over conventional methods are manifold:

• No need of an internal electrolyte: no additional effort, no hidden costs
• No sample flow is necessary for stable sensor response
• No interferences from other gases
• Drift-free measurement ensures extremely precise results
• Low wear and low maintenance due to a long-life membrane head
• Ready for immediate use without warm-up or polarisation times

Functions such as the automatic temperature, pressure and salt compensation are ideal to match individual measuring conditions and make the instrument the perfect all-rounder in water analysis. Calibration data are sensor-specific and stored on the integrated SD card in the unit, which also contains a free software for monitoring, storing and transferring measurement data.

 

Modern technology

• The SD 400 Oxi L uses optical luminescence technology. Your advantage: High measuring accuracy, fast response and absolutely user-friendly measuring.

Low maintenance

• Thanks to luminescence technology, no electrolyte is needed. Regular refilling is therefore no longer necessary - and maintenance is reduced to a minimum.

Data management

• By means of integrated software ("data logger") the collection and analysis of data is simplified.

Suitable for "dilution BOD" determination

• 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.
