TQC Calibration and Maintenance Solutions are essential for calibrating and maintaining the pH and/or conductivity gauge. A wide range of liquid measuring systems is available, in addition to acidity (pH), conductivity (S) and temperature (T), we also have instruments measuring levels of dissolved oxygen and TDS (Total Dissolved Solids), as well as Ion-selective meters. Portable versions and desktop models for use in laboratories.
