METTLER TOLEDO NineFocus pH Sensor InLab Ultra-Micro Pro-DES - 31027067
A pH electrode with a ceramic junction and narrow sensing membrane for small sample volumes or for measuring in small containers, as part of our Diagnosable, Efficient, and Sustainable InLab DES digital electrode line. Designed for use in a variety of applications.
Ideal for critical samples where there is low sample volume or in small containers such as vials and test tubes. Mettler Toledo Micro Series pH Electrodes with ceramic junction allows for accurate measurements no matter the sample volume.

• For use with METTLER TOLEDO NineFocus. Connection cables and signal bridges may be required.
• Features a narrow sensing membrane for small sample volumes or containers
• Diagnosable, efficient, and sustainable (DES) electrodes capture and save calibration data, and the diagnostic system’s preventive maintenance feature maximizes the sensor’s lifespan and prevents premature discard.
• Capture electrode calibration and results with LabX software, designed for advanced data management and 21CFR part 11 regulatory compliance.

Accessories & Care

• Store in 3M KCl (51350072) or InLab Storage Solution (30111142)
• Recommended for use with METTLER TOLEDO buffers (Sachets: 51302080, Bottles: 63056116)
