Seven2Go S4 DO meter - field kit

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 S4 series offer polarographic measurement of dissolved oxygen. For optical measurement see the Seven2Go Pro S9 series.
