GENERAL
This work package contains information and instructions for calibrating the Ultrameter instrument used on the
Lightweight Water Purifier (LWP).
CALIBRATION MAINTENANCE PRACTICES
Total Dissolved Solids (TDS)
1. Clean oily films or organic material from the cell electrodes with detergent. Do not scrub inside the cell.
2. Rinse out the cell with pure water after making measurements. Do not allow slow dissolving crystals to form
in the cell. This will contaminate future samples.
3. For maximum accuracy, keep the pH sensor cap on tight so no fluid washes into the conductivity cell.
CALIBRATION
Total dissolved solids (TDS), conductivity and pH are measured by using the Ultrameter from the BII box. See
Figure 1.
