This Spectronic CamSpec instrument is a true double beam UV-Vis spectrophotometer with a variable bandpass. Parallel sample and reference beams are included as part of the design. Its sensitivity, resolution, stray light, noise and drift specifications are also exceptional. The specification is as expected from a top-of-the-range instrument designed for research as well as routine use.
The M550 true double beam UV-Vis spectrophotometer may be controlled by the UV Analyst software.
See our Standards for UV-Vis spectrophotometers
We are an ISO 9001:2015 company, therefore all of our instruments are individually checked. Using wavelength, absorbance, resolution and stray light standards, these have all been calibrated to international standards.
The M550 fully complies with CE requirements for safety and ESD / EMC emission and susceptibility.
The M550 has a USB data port to enable file transfers
Our M550 has a USB interface for transfer of results to a PC and for PC control of the M550. The comprehensive Camspec UV-Analyst application software is available, together with a number of small PC programs dedicated to specialist tasks.
