Nix QC Manual

Product Mission

It might seem obvious, but every object in the world has a color.

If you’re in the business of researching, manufacturing, producing, inventing, purchasing, or distributing these objects, at some point you must consider a color quality control solution. In the past, this has typically meant either expensive and difficult to use lab equipment, or analog swatches, inspected by eye.

Our goal with the Nix Quality Control Color Sensor (Nix QC) was to hit the elusive sweet spot of highly accurate and innovative technology that’s also extremely easy to use, and in turn provides a high level of color confidence.

To do this we had to build not just a tool, but a system of hardware, software, and adapters that could easily be reconfigured to fit the demanding needs of your particular workflow.

The product that you hold in your hands today is the culmination of years of hard work from a dedicated team of professionals at our home base in Hamilton, Ontario, Canada. We will always push the boundaries and we will always keep innovating to make your life easier, so be sure to keep
your software updated for the latest and greatest features.

On behalf of the entire Nix team I hope that you enjoy your purchase and that it will help you to bring excellence in color quality control to your workplace.

Industry Uses

The Nix Quality Control Color Sensor (Nix QC) is capable of seamlessly fitting into the work flow of any industry. This is because of the Nix QC’s unique ability to measure the color of almost any product – whether it be a solid, liquid, powder, or gel (some materials may require adapters).

A look at some of the materials scanned by the Nix QC…

Downloading the App

The Nix QC hardware requires the installation of the Nix QC App, compatible with Android and iOS.

Nix QC App

Compatible with iOS (11.0 or newer) or Android (4.4 Kit Kat or newer)

With the Nix QC app, you can control and monitor the variance of color in your studied samples. Visualize color deviation between your scanned samples using the color space target zone and identify the direction in which your sample differs from the reference by lightness and hue. For example, learn if a sample contains more yellow than your reference, or if it is darker or lighter. If a sampled color doesn’t meet your set threshold, the scan will be flagged and logged so it can later be referenced. Custom quality control libraries can be imported, and QC thresholds can be set by managers. The color difference (Delta E or ΔE) value to the reference color can be seen for all scans in the sample set.

  • Results displayed in CIELAB and compared to reference color
  • Log of scans in comparison to the reference sample
  • Set custom pass/fail color difference (ΔE) thresholds for sampled colors
  • Multiple color difference (ΔE) modes available, including CIE76, CIE94, CIE2000, and CMC
  • Multiple illuminant and observer scan settings (D50, 2° and D65, 10°)
  • Set multi-point averaging
  • Import custom libraries and export scan data (click here for details and instructions)
  • Allows the user to verify that the Nix QC device is performing within advertised specifications using the provided reference tile

The Nix QC hardware is also compatible with the Nix Toolkit, Nix Paints, and Nix Pro Color Sensor apps.

Turning On & Charging your Device

The Nix QC arrives in a “sleep” state. To wake it up, plug in the provided micro USB charging cable into the USB port on the device (plug the other end into a wall adapter or PC). Once charging, a small blue LED will illuminate on the left side of the USB port on the Nix QC to indicate it’s connected to power. For a full charge, keep your device plugged in for four hours.

You can check the battery level of your device by connecting to the Nix QC app. Select the slider icon to see charge information. Your device must be connected to the app to see this information. Generally one charge will last for 25,000 scans.

A low battery icon will appear in the top left of the screen when a recharge is required.

Note: The Nix QC does not need to be turned off. It will automatically hibernate when the Nix QC app is closed.

Device Set-Up

Connecting to wirelessly

Before attempting to connect to your Nix QC, be sure the device has been woken up and has a charge (see page 13). On your Android/iOS smartphone or tablet, ensure wireless connectivity is enabled in your settings. Open the Nix QC app. The app may request to access your location (this is necessary for wireless connectivity), accept the request.

Place your Nix QC next to your smartphone or tablet. Press the inactive wireless connection icon at the top left of your screen (indicating that a device is not connected). If prompted, select the device with the highest signal strength from the list. Typically it takes 15-20 seconds to connect, but may take up to 60 seconds. You should see an active wireless connection icon  when connected.

Setting the Delta E and Scan Settings

The default Delta E type is CIE2000 and default scan settings are D50, 2°, but these can be customized for your needs. Select the slider icon  in the top right to change these settings. Under “Scan Settings” you’ll find options to change:

  • Illuminant & Observer
  • Delta E Type
  • Delta E Threshold

Remember: Every time the settings are adjusted your new scan logs will be recorded in a new batch and previous scans will be cleared from the plot. To access your data, click on the history icon  from the main screen.

Using the Reference Tile

You will periodically be required to confirm that the Nix QC is within advertised specifications. The app may request access to your camera to scan the QR code accompanying the reference tile (used for the verification process), accept the request.

The app will remind you to verify your Nix QC device by displaying a warning icon at the top left of the screen. Press the icon to start the process. Remember to remove any adapters you may have attached to the Nix QC. Follow the instructions on the app, which will confirm whether or not the device is calibrated to the factory settings.

If you neglect to perform this step when the warning icon is present, each scan will be flagged as being out of spec. You can verify your device at any time within the settings (slider icon ) by selecting “Device Verification” under “Device Information.”

See below for instructions on cleaning the reference tile.

Remember: Always close the reference tile container and store in the included carrying case to prevent dirt or dust buildup which can impact future measurements.

Proper Scanning Technique

Place your Nix QC flat on any solid, opaque surface and start scanning. Remember to keep the device flush with the surface to block out all ambient light for the most accurate results.

Are you using the Nix QC on liquids, powders, gels, or textured and soft surfaces? You may need special adapters to help get accurate readings.

Proper Care & Cleaning

To prevent dust buildup and other damage, always store the Nix QC in the provided Industrial Carrying Case.

Dust can be removed by gently wiping the device with the provided microfiber cloth. To thoroughly clean the Nix QC body, lens, or LEDs, spray the provided cleaning solution onto the cloth and gently wipe down the device (never spray the device directly).

If your reference tile requires cleaning, wipe it with a dry microfiber cloth (provided). Never use any cleaning solution on the tile. Use only the provided cloth, as other materials may be dyed and can stain the reference tile.

Remember: Only use the cleaning solution provided. Avoid other solvents or cleaning products that may degrade the lenses over time.


The Nix QC device should be recertified once per year or if the app indicates that the device calibration falls outside of the factory settings.

Due to the sensitivity of the Nix QC and the specialized equipment that is required, the Nix QC must be sent to Nix Sensor Ltd.’s facility in Canada for recertification.

Nix Sensor Ltd. offers a full-service recertification and inspection that includes:

  • Recalibration using Nix Sensor Ltd.’s proprietary 24 color array (comprehensive, extended gamut)
  • Full inspection of the device
  • Cleaning of lenses and LED light pipes

Remember: Recertification services can only be conducted by
Nix Sensor Ltd. Both the Nix QC and reference tile are required for recertification.
