Density Meter Model DS7800 and Model DS7900
|
| |
Digital density meters can measure density, relative density and concentration of aqueous solutions with up to five decimal places in a range of 0.00000 - 1.99999 g/cm©ø .
Measuring method is based on established oscillating U-tube technology.
The U-tube made of glass is monitored through the window to ensure that no gas bubble falsifies measurement results. |
| |
The device has a high-precision recirculation air-temperature control based on a Peltier element.
Calibration is performed with pure water and dry air.
A dry-air unit and a peristaltic pump for sample handling are included. |
| |
The operation is intuitive and done by a user-friendly touch screen.
All important settings are visible on the main screen and stored in an SQL data base together with measuring results.
Data storage covers last 999 measurements. |
| |
Our density meters comply with ASTM D4052 and D5002.
An active three-level user administration with password protection makes the DS7800 and 7900 particularly suitable for use in GLP/GMP regulated industries. |
