Πληροφορίες προϊόντος

• Advanced LED optical system
· Innovative optical design that utilizes a reference detector and focusing lens to eliminate errors from changes in the light source and from imperfections in the glass cuvette.
· LEDs have a much higher luminous efficiency, providing more light while using less power. They also produce little heat, which could otherwise affect electronic stability.

  • No warm up time before taking a measurement
  • Tutorial mode for step-by-step instructions
  • Uses either powder or cost saving liquid reagents
  • CAL Check
