Automatic Gravimetric Solids and Migration Analyzer
Automate TDS, moisture, pollution, migration-residue and component-cleanliness gravimetric workflows.
A 52-position robotic gravimetric system for water-sample TDS, soil and sludge moisture or pollution analysis, packaging migration residue and electronic-component cleanliness testing.

Workflow and key features
After prepared samples are loaded, the CECW-02B automatically completes vessel handling, drying, conditioned weighing, repeat constant-weight cycles, calculations and reporting. Its application scope covers dissolved solids in water; moisture content and potential pollutant type or concentration in sludge, soil, environmental and stationary-source samples; safety evaluation of food and pharmaceutical packaging or containers; and cleanliness inspection of electronic components.
- Fully automatic robotic operation for up to 52 prepared samples per batch
- Integrated precision weighing records mass to 0.1 mg
- Proprietary low-humidity control isolates weighing from ambient humidity changes
- Automated repeat weighing and constant-weight determination reduce manual transfers
- Stable, adjustable temperature and humidity control with real-time trend logging
- FFU high-efficiency filtered airflow in the work chamber
- Automatic calibration maintains long-term measurement accuracy
- Analysis software completes calculations, batch reports and data export
- Integrated environmental control eliminates the need for a separate controlled evaporation-residue weighing room
- Measures total dissolved solids in water samples
- Supports moisture and pollution analysis of sludge, soil, environmental and stationary-source samples
- Supports migration and non-volatile residue testing for food and pharmaceutical packaging or containers
- Supports electronic-component cleanliness inspection
