Applications
The instrument can be used for 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)
- Purity control and quality control of substances produced by chemicals (chemical products)
- Brix measurement as production process control and quality inspection for milk products, carbonated drinks, fruit drinks, etc.
- Measuring the concentration of alcohol and extracts in beer, sake, wine, etc.
- Brix concentration measurement of sugar solution, syrup solution, isomerized sugar solution, seasoning, etc.
- Pharmaceutical Densitometry Based on Pharmacopoeia
- Quality control of oils and fats such as vegetable oils and animal oils
- Quality control of flavors, chemicals, etc.
- Quality control of surface treatment agents such as etching solution and acid cleaning solution
Features
- The DA-800 series density meters measure the density/specific gravity of liquid samples by employing an oscillating sensor to determine resonant frequency. What’s more, the instruments can calculate sample concentration according to common industry standard formulas and tables.
- The instruments have a built-in temperature stabilizing function, allowing you to measure density/specific gravity at your desired temperature.
- Measurement can be conducted with as little as 1mL of sample (if injected manually), and in as fast as 10 seconds for a temperature-stabilized sample (when viscosity correction is disabled). All models in the DA-800 range come with viscosity correction functionality as standard.
- Data Integrity (DI) support functions are provided as standard to help you maintain and manage your valuable data.
- The interface has been enhanced to support a variety of uses, such as a separate structure for the operation unit (tablet/PC) and measurement unit, wireless LAN connection, and connection of multiple units.
- The instrument has a space-saving design and can be integrated with a semiautomatic cleaning unit (optional). Also included is a camera for viewing inside the measurement cell, improving reliability, convenience, and efficiency.
DI support functions are included as standard
The following features are included as a standard for Data Integrity.
・User authentication : Authentication by personal ID and password is possible.
・Authority management: Possible to set authority such as editing restriction by personnel.
・Audit trail: Possible to automatically record operating history.
・Digital signature: Possible to perform electronic certification and digital signature by workflow.
・Back up/Restore/Archive: Automatic back up function in every optional period
Separate operation unit and measurement unit
・The measuring unit can be placed in a fume hood and operated remotely from outside the fume hood.
・The unit can be operated remotely from a separate location via a wireless LAN connection (optional).
Semiautomatic cleaning unit
・The semiautomatic cleaning unit (optional) is a space-saving design integrated into the measurement unit and enables automatic measurement including drainage, washing, and drying.
High reliability
1) KEM is the only manufacturer in Japan of standard liquids that conform to ISO17034, which is traceable to national standards.
2) KEM oscillation-type density meters are calibrated with international MRA*1-compliant and ISO17025-compliant JCSS*2 laboratory density standards, which are traceable to international standards in the world.
*1 Mutual Recognition Arrangement
*2 Japan Calibration Service System
3) High accuracy (DA-860: 3×10-6 g/cm3)
High repeatability (DA-860: 1×10-6 g/cm3)
High reproducibility (DA-860: 2×10-6 g/cm3)
Equipped with a camera for viewing the measurement cell
1) Improved visibility of the measurement cell.
2) Image inside the measurement cell at the end of measurement can be saved to check the sample status.
Short measurement time
1) The new stability mode developed by improving the conventional algorithm was added to shorten the measurement time.
2) The shortest measurement time is approx. 10 sec when the temperature is stable.
Multiple management by a single operation unit
Multiple measurement units (max. 4 units) can be operated simultaneously by a single operation unit and the data can be managed comprehensively. (optional)
