78XX Series Ultraviolet Visible Spectrophotometers

¡¡

7802 Series Ultraviolet Visible Spectrophotometers are auto scanning types which are mounted with step motors. All Ultraviolet Visible spectrophotometers feature high performance sealed optics mounted on a stable machined platform. The innovative optical layout and state of C-T monochromator with high grade blazed holographic grating ensure accuracy. Its integrated design assures long-term stability and durability. The precisely aligned detector, quality deutierium lamp and tungsten lamp enhance the precision across the UV/VIS spectrum. All spectrophotometers are intended to be utilized for research, development, quality control, etc. primarily in the fields of optical materials, semiconductors, new materials, electronics and so on through qualitative and quantitative analyses of samples diverse in kind and size. The comprehensive features, sophisticated powerful software, variety of accessories and model configurations will meet or exceed your expectations for performance and value.

Features:

¡ôThe 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.

¡ô Pre-aligned deutierium lamp and tungsten lamp for easy lamp replacement.

¡ô The innovative optical layout ensures accuracy. Its integrated design assures long-term stability and durability. The precisely aligned detector and tungsten lamp enhance the precision.

¡ô The large sample compartment accommodates a wide range of cell holders and accessories including Peristaltic Sipper, Peltier System and Specular Reflectance Attachment.

¡ô Perform basic Abs / %T / Conc / Abs vs. Time (impact printer such as Hp or Epson needed) tests.

¡ô It has a 20X2 LCD screen with contrast adjustment for comfort viewing to display all of the parameters.

¡ô The backup battery and the integrated circuit design controlled by MCU assure non-volatile memory storage.

¡ôEvery spectrophotometer has an exclusive ID. Get the ID from pressing the SET key on the panel. When connect with powerful Windows ? - based application software , this ID is used to verify its validity.

¡ô Hp and Epson driver programs for impact printer have been installed into MCU, the parallel printer port can connect with impact printer directly, such as EPSON-LQ-300K(option). The basic Abs/%T/ Conc tested data can be printed directly, also it can perform Kinetics test.

¡ô Real-time clock for year, month, date, hour, minute, second and time stamping of results.

¡ô Sealed and solvent-resistant tactile keypad.
