The portable meter SD 310 Oxi meets the day-to- day demands for sturdy and reliable measurement of dissolved oxygen and completes the SD 300 series.
The well-known Clark-oxygen-sensor with integrated temperature compensation allows instant measurement without the need for time- consuming polarisation.
A direct, convenient user interface facilitates meter operation both outdoors and in the laboratory.
The automatic hold function “freezes” measuring data in the display, and makes them easy to read.
The internal memory allows storage of up to 1,000 data sets. Also an internal data logger enables continuousley monitoring of measurement results. Monitoring becomes even more convenient with the alarm function.
The water-tight housing (IP 65 & IP 67) together with the rugged and protective armour ensures reliable operation even in extreme ambient conditions.
The support can be flipped up to hang the meter on pipes or branches or for fastening to a belt.
