METTLER TOLEDO NineFocus pH Sensor InLab Solids Pro-DES - 31027063
A low maintenance glass pH electrode with an integrated temperature probe featuring a clog-free, open junction that eliminates the risk of protein fouling, as part of our Diagnosable, Efficient, and Sustainable InLab DES digital electrode line. Designed for use in a variety of applications.
Ideal for solid samples such as meats, dairy, and fruit and vegetable products. Mettler Toledo Solids Series pH and pH/ATC Combination Electrodes with open junction puts the reference electrode in direct contact with the measured medium, eliminating the possibility of contamination or blockage.
