Meters

A Wide Range of Light Meters for a Variety of Applications
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:G and R Labs - Model 400 MeterThe 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 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 (20MW/CM2) in two scale positions.
  • Model 200:G and R Labs - Model 200 MeterThis 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: The LM-120 Photometer measures Lux/Footcnadles on a 3 ½ digit (1999 count) LCD Display. The LM120 is auto Ranging from .01 to 199,900 Lux and .01 to 19,990 Footcandles. Calibration is to a +/- 1% standard traceable to NIST with certificate. The Meter comes with case and manual. Selling Price $210.00.
  • 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.
