VIS/UV Light Meter Calibrations


Delivering Consistent, Reliable, Quality Calibrations

When it comes to calibrations, it’s important to find a qualified calibration company that can accurately perform light meter calibrations. It’s easy to find a company that can calibrate your instruments but having a qualified vendor that can provide consistent accurate calibrations each time is time is invaluable.

At Constellation PowerLabs, we strive to provide accuracy in everything we do and offer a diverse array of calibration services that are traceable to both national and international standards. As an accredited laboratory, we are routinely audited by A2LA for our ISO 17025 capabilities and assessed by NUPIC and NIAC under our Appendix B program. While we are not accredited in our light meter calibration services, we take it upon ourselves to calibrate every component diligently and provide our customers traceable light calibrations


Our Light Meter Calibration Capabilities

Light meters are essential to measuring the amount of light within a specific area. With light meters, our laboratory’s main headquarters performs two types of light calibrations: visible and dark light / ultraviolet light. Light meters are used to measure light intensity or illuminance.

We provide the following light meter calibration ranges:

  • Visible Light (white light, @2856K) up to 1,000 foot-candles (10,764 lux) (≈2% of reading)
  • UVA (black light, @365 nm) up to 1000 µW/cm² (≈3.5% of reading)

As we service customers from all across the world, we often see similar types of equipment come in through our labs regularly. While we calibrate mostly digital light meters, we also calibrate the following manufactures: Extech, Spectroline, Minolta, Greenlee, Osram, Sylvania, Tenma, Magnaflux, AEMC Instruments, etc.


The Importance of Light Meter Calibration

It is necessary that your lighting standards read accurately as it can have an impact on safety and production. As with any instrument, overtime, it can drift leading to inaccurate readings. Light meters can be used in a variety of applications.

No matter the difference in the lighting application, we understand how important it is for your equipment to work efficiently as there are many factors that can be impacted if it doesn’t. At Constellation PowerLabs, we’re here to provide you with reliable light calibrations you can count on every time.

Visible Light Applications:

For visible light measurements, light meters are often used for measuring the lighting in buildings as this can be a safety and concern if exposed to too much lighting, or even too little. This can be critical to daily operations if a hospital or manufacturing facility didn’t have adequate lighting.

Dark Light or UV Light Applications:

UV light can be dangerous when working if exposed for a certain amount of time. This can affect the temperature of a space or items in the room, which can impact the environmental conditions. To ensure you meet OSHA compliance, it’s important that your light meter equipment works properly for the safety of your employees and the facility.


Our Process

With light meters, each display has a sensor/detector, whether it’s for visible or UV light meters. When we calibrate, our technicians position the reference plane of the sensor coplaner with reference surface of our standard sensor.

Both are then positioned to obtain a certain measurement point using an appropriate light source. The sensors are then alternately positioned in the light beam of the source and readings compared.
