Data Acquisition and Control Software |
The OSM-Analyst Basic is the standard software package delivered with each OSM instrument. This Windows application has all the same features as the on-board software of the OSM-400 instrument, as well as the special features, listed below. An Active X Component allows quick development of your measurement sequences. |
Start measurements in absolute, reflection, transmission, absorption, optical density and background subtraction mode - Perform basic mathematical operations with your spectra, such as addition or multiplication with other spectra or a value
- Display multiple spectra at the same time in different colors
- Freely zoom in and out
- Save spectra in SPC format (GRAMS Standard) and in CSV format for further operation in other software packages such as Excel or MATLab
|
Rechargeable Batteries |
These instruments are truly portable. Not only do they have an on-board microprocessor and touch-screen display (eliminating the need for a PC), but they have rechargeable batteries for field operation (OSM2-400 models, only). Fully charged batteries run for up to 4 hours. |
