Laboratory instruments for liquid analysis, such as the polarimeters, refractometers, photometers and density meters manufactured by Schmidt + Haensch, are required in almost every laboratory of the food, pharmaceutical, chemical and petrochemical industries.
Laboratory instruments are using different physical measuring principles.
Polarimeters are measuring optical rotation of polarised light passing through optical active substances.
Refractometers are measuring the refractive index of liquids by measuring the critical angle of refraction. The refractive index is directly linked to the concentration of the solution.
Photometers are measuring the absorption of light in liquid samples at different wavelengths.
Density meters are using the proven oscillating U-tube principle.
The modular concept enables the combination of different laboratory devices for customized analysis.
