Detailed Product Description
1. Features:
a | The spectrophotometers perform built-in wavelength calibration program automatically after energization. Core components will be check during the initialization to ensure the wavelength accuracy and excellent performance |
b | Pre-aligned deuterium lamp and tungsten lamp for easy lamp replacement. The light source changing point can be set in range of 300nm - 400nm |
c | The innovative optical layout ensures accuracy. Its integrated design assures long-term stability and durability. The precisely aligned detector and quality deuterium and halogen lamps enhance the precision. |
d | Perform basic mode( Abs / %T), quantitative |
e | Pre-set wavelength program (4 wavelengths), and one-touch key response |
f | Single-point curve calibration and multi-point curve calibration (up to 12 points) |
g | Display of fitting degree of curve fitting and concentration data with up to 50 sets of curve parameters storage |
h | Display of concentration data with up to 200 sets of data storage |
i | Dark current calibration / wavelength calibration/System clock management |
j | Backup battery and integrated circuit design controlled by MCU assure non-volatile memory storage |
k | USB data communication |
l | LPT port for printing |
