Features and benefits

ASD QualitySpec Trek is a general purpose, all-in-one, full-range, portable spectrometer measuring the visible and shortwave infrared regions (350-2500 nm). The instrument is designed for portable spectroscopy and includes an integrated internal light source, on-board GPS, voice audio recorder for expanded sample descriptions, internal white reference for hands-free optimization and calibration, lightweight rechargeable lithium ion batteries, automated internal wavelength validation, integrated computer and LCD display with easy push button navigation and a PC-based project and data management software ecosystem.

Additional ASD QualitySpec Trek features and benefits:

  • Compact and portable: Lightweight yet rugged design allows unprecedented portability in a full-range highly accurate spectrometer.
  • Fast and accurate: Enhanced spectrometer configuration builds on the trusted legacy of ASD for unparalled accuracy and performance.
  • Cable free: Remove cable management from your data collection workflow with a truly cable-free integrated spectral collection system.
  • Integrated computer and LCD: On board computing and LCD display eliminates the need for 3rd party laptops or hand held devices. Simplify your workflow and leave your PDA at home.
  • Audio voice recorder: Automate your field notes with the convenience of voice memos. The QualitySpec Trek’s audio voice recorder feature can record useful descriptive information for each data point measured.
  • Internal wavelength and white reference capability: On-board internal referencing features ensure instrument performance, high data quality, and liberates the operator from the necessity of frequent white reference measurements.
  • On-board GPS: Automatically populate accurate coordinate and elevation data for every measurement.
  • Sample clip: Each QualitySpec Trek is shipped with a second magnetic external white reference that serves as a sample clip for scanning thin samples such as parchment, foliage, or fabric.
  • Data management: Review and enlarge spectra on the device or on your laptop with the PC Manager. Laptop software allows for easy spectrum, file and project management.
  • Multiple languages: QualitySpec Trek is ready to address global markets with fully integrated English, Mandarin Chinese, and Spanish language options.
