Type Polartronic N, M, and H series
The continuously measuring, fully electronic circle polarimeters of Polartronic series N, M, and H read the rotation angle directly for unmatchable precision over the entire measuring range and short measuring times. They are primarily intended for laboratory applications in R&D and in the pharmaceutical industry. In addition to versions with an LED illumination unit (with an extremely long life time of approx. 50.000 h), Schmidt & Haensch also offer polarimeters with spectral lamps. These units are equipped with up to 5 wave lengths and require next to no calibration. Comfortable, user-friendly software for GMP-/GLP-compliant documentation of data at the PC or printer. CFR21 Part 11 Software (Aquisys 2008) is available as an option.
Thanks to the modular manufacturing concept, users can choose a unit tailored to their applications (different precision classes, suitability for micro tubes, AWC – Automatic Wavelength Control, wave lengths).
