Light Meters
Measure light quality and intensity with these meters. They’re CE marked, so they meet European safety standards. They should not be used with lasers.
These meters measure brightness in footcandles and lux. One footcandle is one lumen per square foot. One lux is one lumen per square meter.
Use the data hold function to freeze a measurement on the screen, giving you time to write it down. Some meters also have an analog output, which transmits data to a recorder. Meters with minimum/maximum memory let you save and retrieve the high and low measurements you’ve taken. Meters that include an SD card store timestamped readings in Excel format for logging data and transferring it to a PC.
All of these meters measure general lighting. Style A meters measure white LED light. Style B meters measure colored LED light. Style C-E meters measure general lighting only—they are not for use with LED lights.

Light Meters for UV Light
Measure the intensity of UV light to track equipment performance and ensure safety. These meters are often used in sterilization systems, curing applications—such as coatings and adhesives—and for monitoring blue-light UV radiation from welding equipment. All have a data hold function, allowing you to keep measurements on the screen so you have time to write them down. To preserve battery life, they shut off automatically. These meters are CE marked as meeting European safety standards.
Always wear UV-protective glasses and clothing when collecting measurements. These meters are not for use with lasers.
Meters for UV-A and UV-C wavelengths measure with two sensors, one for long-wave light and one for short-wave light. An included SD card stores timestamped readings in Excel format for transfer to a PC. Save and retrieve the high and low measurements you’ve taken using the minimum/maximum memory feature. The built-in tilt stand props these meters up, so you don’t have to hold them.
Plug an optional thermocouple probe into meters for UV-A and UV-C wavelengths to measure surface temperature. These probes are often used in curing applications to make sure material has reached the required temperature.

Gloss Meters
Confirm that each product is as shiny as the last. These meters measure the gloss of paint and coatings as well as metal, ceramic, and granite surfaces. All come with a USB cord to transfer data to PCs.
Meters with a 60° field of view can evaluate the gloss of most standard, semi-gloss surfaces.
Meters with a 20°, 60°, and 85° field of view can evaluate low-gloss/matte and high-gloss surfaces in addition to semi-gloss surfaces—their gloss measuring range is 10 times as broad as meters with only a 60° field of view. They’re compatible with a free app that lets you use your Android device to start and stop recording and send data using Bluetooth.
These meters come with a calibration block, and you should calibrate them before each reading. Lay the block on a flat surface and press the calibration button on your meter. Position the meter on top of the block, and your meter will calibrate.

Color Calibration Plates for Colorimeters
Calibrate your colorimeter so it can identify colors with precision. The white block calibrates your colorimeter because the machine measures all other colors according to their variance from true white. The four colored blocks are particularly helpful in quality control applications, where you want to make sure a specific color is consistent unit-to-unit. Made of ceramic, these plates won’t degrade, warp, or discolor over time, ensuring reliable measurements. Their surfaces are smooth and easy to clean, so they resist scratches that could affect readings. These plates are precisely manufactured to ISO/IEC 17025 standards for testing and calibration equipment.

Colorimeters
Ensure consistent coloring on products such as labels and packaging. The sensor on these colorimeters translates the light an object reflects to an exact color reading. Use them for quality control to prevent slight variation that you might miss with your eyes alone. Calibrate your colorimeter using the included white calibration block. The machine measures all other colors according to their variance from true white.
Color calibration plates (sold separately) test and calibrate your colorimeter. They include five colors across the color spectrum to give the device a reference point for exact color readings. Precisely manufactured to ISO/IEC 17025, these plates meet standards for testing and calibration equipment.
