Product Description

General Concentration Meter <DA-6XX+RA-6XX>

The two sensors each for density and refractive index need just small amount of sample liquids in order to simultaneously measure both density (specific gravity) and refractive index.
The built-in thermostat controls measurement temperature in a short span of time to preset degree for precise and quick measurements of both density (specific gravity) and refractive index. The measuring units each for density (specific gravity) and refractive index can individually control and preset temperature.
Density measuring unit features viscosity correction for samples of higher viscosity, allowing measured density values to be compensated.
Measuring range is wide enough to measure any kinds of samples: Density : 0 to 3 g/cm3 Refractive index: 1.32000 to 1.58000 (DA-645+RA-620)
The optional USB allows you to expand the versatility of operations including more storage space of measurement parameters and data as well as a user's own concentration conversion tables.
The optional data acquisition software designed for DA-6XX+RA-6XX allows you download measurement results to PC so that the data can be further processed according to a user's needs and requirements for easier management of acquired data.
The commercially available bar code readers compatible with RS-232C serial interface can be connected to AUX port and conveniently read sample ID and lot number.
