Since 1995, companies who measure light in Deep UV, UV, Visible and near infrared spectrums have turned to G&R Labs for cost effective solutions for their light measurement needs. G&R is a customer-centric company understanding that anyone who needs to measure light must have accurately calibrated light measurement equipment they can rely on.
Because eliminating downtime is critical to any environment, G&R Labs focuses on providing optimum light measurement solutions—quickly.

With a range of light measurement instruments measuring intensity from 220nm to the near infrared, G&R Labs offers the proper light meter or light meter probe for various light measurement applications. Choose from light meter and light sensor packages such as our top of the line Model 400 light meter measuring MW/CM², MJ/CM², time, and light uniformity in a number of light measurement situations, or our single range Model 100. Visit our Products page for complete light meter or light meter probe listings and specifications.

Each light intensity meter is manufactured in an ISO-9001-2008 facility to ensure a quality light measurement device guaranteed for accuracy.

Focused on optimizing product usage, G&R Labs’ light meters are designed to use multiple light meter probes, allowing the use of the same light meter for a wide variety of light measurement applications. If you trade in your existing light meter, G&R Labs will issue a credit against a new light meter. For additional savings, many times another manufacturer’s light meter probe can be modified to work with a G&R Labs’ light measurement meter.

In addition to providing light meters, light meter probes, and light meter calibration, G&R Labs’ can solve light measurement challenges with light sensor packages of all shapes and sizes to fit in many places. One seemingly insurmountable challenge was a request for a very small light sensor package that was the same size as the product being exposed. G&R Labs solved that challenge with a light sensor package 0.31 (7.9mm) thick with five sensors measuring the light intensity at five different points. Another application called for the light sensor package to be at a fixed angle with a slit opening to the detector. G&R Labs was able to achieve this goal. Always up for a challenge, G&R Labs was also able to provide a small round light probe on a tube to look at a single LED on an array. This was difficult because the processing of the measurement had to compensate for being too close to the LED so all the measurements were the same.

That’s correct—one day is the standard turnaround time for G&R Labs light meter calibration. G&R Labs services most light meter manufacturers such as OAI, Nikon, PE, HTG, ABM, Mimir, JBA, Ultratek, and many more.

And—all G&R Labs light meter calibration services are traceable to the National Bureau of Standards (NIST) with a +/- 0.5% in-house standard for radiometric calibrations and an in-house +/- 1.0% standard for photometric calibrations. The 3 Sigma accuracy to the calibrated probe is +/-3.0% maximum, but G&R Labs standard is a +/-1.0% window from calibration to calibration.

How do we provide accurate light meter calibration so quickly? It begins with the initial contact. When you call G&R Labs, you always reach a “live” operator ready to direct you to the correct support personnel. Send us an email and it is always answered promptly—our staff is committed to responding to all inquiries. Ship your light meter overnight Monday for light meter calibration services and you can be back up and running by Wednesday. Down time eats into productivity, costing valuable $$ and G&R Labs make sure they do their part to reduce this. Visit our Services page for complete details on UVA meter calibration, UVB meter calibration, and UVC meter calibration services.

It easy to see why G&R Labs has earned the title “Light Measurement Specialist.” Contact us today and let us supply you with the expertise to solve your light meter calibration, light meter or light meter probe challenges.
