Product Features:

  1. Uses an ARM system with a built-in dual Chinese-English operating system, allowing data storage and transfer via USB interface.
  2. Powerful functionality: The main unit can independently perform photometric measurements, quantitative measurements, spectrum scanning, kinetics, DNA/protein testing, multi-wavelength testing, and data printing.
  3. Equipped with a 320×240 high-brightness 6-inch LCD display, which directly shows scanning spectra with a simple and user-friendly interface.
  4. Designed with a high-performance optical system, a high-quality 1200 lines/mm grating, and an imported detector to ensure excellent performance.
  5. Features a socket-type neon and tungsten lamp design, eliminating the need for optical calibration after lamp replacement.
  6. Utilizes a 24-bit high-speed, high-precision A/D converter, ensuring high accuracy and fast response.
  7. Spacious sample compartment that accommodates cuvettes of various sizes (5-100mm).
  8. Can be directly connected to a printer for printing spectra and experimental data.
  9. Supports direct online operation via scanning software.

Main Functions:

With simple parameter settings, the instrument enables convenient photometric analysis, quantitative analysis, kinetic testing, spectrum scanning, multi-wavelength testing, and DNA/protein analysis.
