METTLER TOLEDO NineFocus pH Sensor InLab Micro Pro-DES - 31027062
A combination 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 and pH/ATC Combination Electrodes with ceramic junction allows for accurate measurements no matter the sample volume.
