Skalar implements Optical Oxygen probe for BOD and DO measurements

Dissolved oxygen (DO) is one of the most important parameters monitored when evaluating the water quality. <?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

 

 SP1000 BOD

 

Since the 80’s Skalar automated the labor-intensive Biochemical Oxygen Demand (BOD) analysis on its range of Robotic Analyzers. Skalar is continuously developing its analyzers with the latest innovations. Recently the optical dissolved oxygen probe has been implemented on the Skalar Robotic Analyzers for use in BOD and DO measurements.

 

Dissolved Oxygen ProbeSkalar Robotic Analyzers fitted with this new Optical DO probe have a faster response time and therefore higher sample throughputs can be achieved.

Immediately after loading the samples, the analysis can be started. Daily probe calibration is not required anymore and calibration is limited to once per month. The probe requires minimal maintenance and there is no need to replace electrolyte solutions or membranes. Annual replacement of the sensor cap is sufficient. 

 

All Skalar Robotic Analyzers (SP10, SP50, SP100 and SP1000) can be equipped with this new Optical DO probe. Custom-made configurations are available based on sample load, with multiple probes/meters, automatic dilution, ATU / seed dispensing, automatic capping/de-capping etc., meeting the requirements of any laboratory. From 32 up to 120 BOD bottles can be set as uninterrupted sample batches. Sample trays can be added during analysis runs to handle any required sample load.
