The KEM’s DA-800 series density meters measure density and specific gravity of liquid samples using an oscillating sensor to determine resonant frequency. Additionally, these instruments can calculate sample concentration based on widely accepted industry formulas and tables.
Measurements can be performed with as little as 1mL of sample (when injected manually) and results can be obtained in as fast as 10 seconds for a temperature-stabilized sample (without viscosity correction). All models in the DA-800 range include viscosity correction functionality as a standard feature.
To ensure data integrity, the DA-800 series offers support functions for data maintenance and management.
Features:
- Built-in temperature stabilization function - allows for density and specific gravity measurements at any desired temperature.
- Enhanced Interface - accommodates various applications, including a separate structure for the operation unit (tablet/PC) and measurement unit, wireless LAN connectivity, and the ability to connect multiple units simultaneously.
- Camera-equipped - for improved reliability, convenience, and efficiency when viewing inside the measurement cell.
- Compact design – it is space-saving and can be integrated with an optional semi-automatic cleaning unit.
Automatic wash stations for up to 3 solvents are available as well as automation with sample changers.
Applications
Liquid concentration control and quality control in the following segments: determination of transaction prices and taxes for crude oil and petroleum products (fuel oil and lubricants), chemical products purity and quality control, production process control and quality inspection for milk products, carbonated drinks, fruit drinks, measuring alcohol and extracts concentration, brix concentration measurement of sugar solutions, pharmaceutical densitometry based on pharmacopoeia, quality control of oils and fats, flavors, chemicals, surface treatment agents.
*: The above accuracy is guaranteed in the temperature range of 0 to 90°C with all series.
**: According to ISO 5725 under ideal conditions.
