cloud-runner Mottling Meter

Control and guarantee a uniform finish - no more mottling!

Irregular lightness variations are objectively measured with BYK-Gardner's newest innovation: the cloud-runner simulates visual evaluation under different observing angles and characterizes clouds / mottles by their size and visibility.

Objective and reliable values for QC and trouble shooting

  • Small to large mottles are measured under three observing angles
  • Scan length can be varied from 10 to 100 cm
  • Objective measurement results independent of color and curvature
cloud-runner Mottling Meter


  • Ideal tool for the production line
  • Small and light weight - easy to handle
  • For flat and curved areas, radius > 50 cm
  • Easy, menu guided operation via scroll wheel and large, multilingual display
  • Full statistics with ability to save in selectable memories
  • Large memory for 1000 readings
  • USB port for data transfer to PC
  • smart-chart software:
    • Organizer files for sample id
    • Data management with SQL Database
    • Standard QC Report
  • The mottle meter is operated with a rechargeable battery pack (Li-Ion). The docking station automatically charges the battery pack and transfers the measured data to the PC.

Training for cloud-runner

More than just an instrument. Get assistance in operating the cloud-runner system and understanding your mottle readings. As a result you will be able to use the mottling meter to save time and money and at the same time improve your quality. Therefore, the instrument comes with a one day training course including:

  1. Mottling Theory
    • Visual perception and instrumental measurement of Mottling / Cloudiness
    • Data interpretation: How can the readings be used to optimize process and material parameters
  2. Operation and Software Training
    • Set-up of an "Organizer" to create a routine measurement procedure
    • Programming of the instrument with "organizer" and measurement of several samples
    • Direct data transfer to Excel for documentation of individual readings
    • Data transfer to smart-chart software and saving in a database for routine QC
    • Data analysis The training can be performed in one day or two half days. It is recommended to split the training into two half days:
      • Day 1: Theory and basic operation (set-up organizer, taking readings and saving data in a database)
      • Day 2: 3-4 weeks later to ensure readings were taken and saved in a database. Data analysis and standard QC reports can be explained using customer specific data.
