Truly Universal and Reliable
S220 pH/ISE meter
The SevenCompact series combines precise electrochemical measurement technologies with flexibility, innovative design and ease-of-use.
The SevenCompact pH/Ion meter S220 is the perfect choice for a wide range of applications. It is much more than a pH meter: it can also measure ORP and ion concentration in various units. Starting a measurement or calibration has never been easier, requiring only a single key press.
Reasons for SevenCompact
- Fast and accurate measurements
- User-friendly operation
- Menu guidance in 10 languages
- Clear, well arranged colour display
- Many peripheral options
- GLP compliant
Productive Work from the Start
Intuitive and Powerful
The instruments functionality has been designed to maximize the productivity of your work. Stand alone, the instrument already offers much functionality, but you can achieve higher efficiency and flexibility by connecting peripherals.
Security
The instruments versatility is also reflected in its security package. Users requiring little or no GLP support can easily use the instrument without worrying about security settings. Still they benefit from the functionalities that minimize mistakes, such as calibration support and Intelligent Sensor Management (ISM®). On the other hand, those that need full GLP support will have peace of mind when employing the full spectrum of security functionalities.
All Parameters or the Essentials Decide by a single key press
The instrument gives you the choice! In the normal screen layout, all available information is visible. By switching to the uFocus view you will not be distracted by information of less importance.
Perfect Ergonomics and High Productivity with uPlace
uPlace: the electrode arm can be operated with one hand; moving straight up and down. This allows for faster measurements and reduces the risk of the sample vessel tipping over and/or damage to the sensor!
Total Flexibility with Data Processing
Upon reaching endpoint SevenCompact allows multiple archiving options: the data can be stored, printed or transferred to LabX direct. Any combination of these three options is possible giving you total flexibility.
