Seven2Go Pro S9 DO meter - meter only, no electrode

Simple, reliable and robust. The new Seven2Go portable meters offer fast, quality dissolved oxygen measurement for laboratories, manufacturing, processing and environmental applications.

Simple menu for intuitive operation offers out of the box operation for anyone.

The new T-pad operating buttons mean you can move through menus faster, giving a shorter time to actual measurement.

ISM Ready for reduced chance of error. When any InLab ISM (Intelligent Sensor Management) electrode is connected the instrument automatically recognizes the sensor and stores the sensor ID, serial number and last calibration data.

IP67 protection and drop test resistant for a weatherproof and robust design. The meters are able to withstand harsh and demanding environments.

This S9 Pro series additionally offers 12 languages in clear complete words and sentences for simple operation, a sunlight proof screen for brilliant readability even under direct sunlight and an LED status light for a quick readiness check using a simple traffic light system to show if your meter is ready to use.

These S9 meters use optical DO probes, for polarographic sensors see the S4 basic range.
