General Information
2.1.3 Class 1 LASER
A Class 1 LASER is installed in this instrument. Class 1 LASERS
are products where the radiant power of the LASER beam
accessible (the accessible emission) is always below the Maximum
Permissible Exposure value. Therefore, for Class 1 LASERS the
output power is below the level at which it is believed eye damage
will occur. Exposure to the beam of a Class 1 LASER will not result
in eye injury. Class 1 LASERS may therefore be considered safe.
However, Class 1 LASER products may contain LASER systems of
a higher Class but there are adequate engineering control
measures to ensure that access to the beam is not reasonably
likely. Examples of such products include LASER printers and
compact disc players. CDRH assession number 0510555-01.
Data: 0.3 mW; wavelength = 650 nm
2.2 Overview of Product/Function
The DR 2800 Spectrophotometer is a visible spectrum
spectrophotometer with a wavelength range of 340 to 900 nm for
laboratory and field analysis. The instrument comes with a
complete set of application programs and multi-language support.
The DR 2800 Spectrophotometer contains the following application
modes: Stored Programs (pre-installed tests), Barcode Programs,
User Programs, Favorite Programs, Single Wavelength Mode,
Multi-Wavelength Mode, and Time Course Mode.
The DR 2800 Spectrophotometer provides digital readouts in direct
concentration units, absorbance, or percent transmittance.
When a user-generated or programmed method is selected, the
on-screen menus and prompts direct the user through the test.
This menu system can also generate reports, statistical evaluations
of generated calibration curves, and perform instrument
diagnostic checks.
This symbol indicates that the instrument contains a Class 1 laser device.
