Meters

G&R light meters measure light in the spectrum from 220nm to the near infrared. Depending on their specific light measurement application, customers can choose from a light measurement instrument range that includes:

• Model 400:The top of the line light meter measuring MW/CM², MJ/CM², time, and calculating light uniformity in a number of measurement situations, Model 400 is a light measurement instrument with diverse capabilities. A built in computer allows Model 400 to store sensor readings and calculate average values, percent deviations and other data values.
• Model 320/322: A simplification of Model 400, Model 320 measures MW/CM², peak MW/CM², MJ/CM² (single pulse), accumulated MJ/CM², time (single pulse), and accumulated seconds. The Model 322 is a Dual channel version of the Model 320.
• Model 324: The Model 324 has computer interface with many of the features of the Model 320 with the eception of the Pulse measurement mode. Measures MW/CM², Peak MW/CM², (SP) MJ/CM², time (seconds), with Average MW/CM² and Peak MW/CM².
• Model 220: The Model 220 measures both MW/CM² and MJ/CM² in a range from .01 to 19,999. The MJ/CM² is either single pulse or accumulated value (switch selected).
• Model 202: Model 202 light meter operates from a single 9-volt battery and has a light measurement range from 1.00 MW/CM² to 19.999 W/CM² (20W/CM²) in two scale positions.
• Model 200:This intensity light meter is a single channel version of Model 202, with the same measurement range.
• Model 100: A simplification of Model 200 Intensity Meter, Model 100 has a single measurement scale of either 1999.9 MW/CM² or 199.99 MW/CM², reducing the investment.
• Photometer LM-120: Reads in Footcandles and Lux.
• Solar Meter: G&R Labs has developed a solar meter that measures the sun’s energy in the same spectrum (.3 to 1.1 Microns) as a solar panel.

See our Meter Comparison Sheet for the specific differences between all our light meter models. All G&R Labs’ light meters meet all the requirements of IEC, UL, and CSA.
