Mettler Toledo – pH/Cond meter SevenDirect SD23 (30671553)
Manufactured by Mettler Toledo
The SevenDirect SD23 Mettler Toledo pH and Conductivity Meter enables laboratories to carry out pH and conductivity measurements separately or simultaneously, e.g. in water analysis.
The instrument is delivered with an EasyPlace sensor arm, preventing sensor damage and ensuring precise positioning, even with one hand. It has a large 7” colour touchscreen with an intuitive interface, providing direct measurement and easy data entry.
This benchtop pH and conductivity meter provides reliable measurements of almost any sample. It then stores the data, such as timestamp, sample, and sensor ID with every measurement, and prints or exports records automatically.
