Description

inoLab® Oxi 7310 – The essential benchtop oximeter for reliable and documented dissolved oxygen measurements

The inoLab® Oxi 7310 oxygen meter is the gold standard for dissolved oxygen measurement in modern laboratory environments. Designed by WTW, this model combines the precision of a high-tech device with optimised ergonomics for everyday use. Its intuitive operation via a backlit graphic display and plain-text menu make it easy to use, even for inexperienced users. Thanks to its compatibility with high-quality galvanometric sensors, it meets the requirements of laboratories seeking performance, safety and traceability of measurements.

This model stands out in particular for its active AutoRead mode, which automatically detects when measured values have stabilised, ensuring flawless reproducibility. The inoLab® Oxi 7310 also features an automatic atmospheric pressure compensation system, making results even more accurate. In terms of compliance, it offers rigorous data documentation in accordance with GLP/AQA standards, with the option of recording electrode serial numbers and exporting data in .csv format to a computer via its USB interface. For added flexibility, a version with an integrated thermal printer is also available.

The device allows comprehensive measurements, ranging from dissolved oxygen concentration to partial pressure and percentage saturation. It is also equipped with salinity correction functions, which are essential for specific samples. With extended storage capacity for measurement series and an integrated logger, the inoLab® Oxi 7310 is designed to handle extensive analysis campaigns.

Finally, it can be combined with the StirrOx® G self-stirring sensor, a major advantage for applications requiring constant stirring, improving measurement accuracy without manual intervention. Whether for an environmental, academic or industrial laboratory, this oximeter guarantees reliable performance over time.
