Precise temperature control using Peltier technology
High-precision measurements through temperature control without an additional device – this is what our polarimeter models P8000-P and P8100-P offer, which otherwise have the same functional scope and the same characteristics as the other devices of the P8000 series. They are recommended if the temperature of the sample is to be controlled extremely accurately within a very short period of time and with a short control cycle and independent of the outside temperature.
- Temperature measurement directly inside the sample
- Accurate, homogenous, fast Peltier temperature control
- Chemical-resistant, unbreakable measurement tube
- Highest accuracy over the entire measurement range
- Very short measurement time of approx. 1 s
- Measurement up to an optical density of 3.0
- Intuitive operation via touch-screen display
- Predefined scales (opt. rotation, spec. rotation, int. sugar scale, concentration)
- Any number of freely definable scales with conversions based on tables or formulas
- Chemical-resistant materials
- Compliance with GMP/GLP, 21 CFR Part 11, Pharmakopöen (USP, BP, JP, Ph. Eur.), FDA, ISO, HACCP, OIML, ASTM, ICUMSA, NIST

Conformity with national and international standards
A big advantage of normalized measurements is the comparability of the measurement results. In many international standards and guidelines, polarimeters are recommended for specific measurement tasks as suitable measuring instruments. The requirements for the measuring devices, such as measuring accuracy and measuring temperature, are dependent on the respective measuring task and defined in each standard. We have compiled for you an overview of all known standards and guidelines, which refer to polarimetry.
