Benchtop Spectrophotometer SPE71-420

Benchtop Spectrophotometer is used for measuring the color and appearance of fluorescent, opaque, transparent and translucent samples under various illuminants

  • Double Array 256 Image Element CMOS Sensor; Long life-span stable LED UV LED.
  • With reflective and transmissive spectrum, accurate Lab value, good to calculate color formula and do precise color transmission.
  • Auto identify measuring aperture. Freely switchable between 3 measuring apertures: Φ 25.4mm/8mm/4mm. Users also can customize apertures.
  • Built-in temperature sensor to monitor and compensate the measuring temperature to ensure the measurement more precision.
