Light Meter Summary

A Wide Range of UV 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 100:  The Model 100 has a single measurement scale of either 1999.9 MW/CM2 or 199.99 MW/CM2.
  • Model 200:  G and R Labs - Model 200 MeterThis UV Light Meter  measurement range is from 1.00 MW/CM2 to 19.999 W/CM2 (20W/CM2) in two scale positions.  The peak switch allows measuring and holding the maximum reading that the probe encounters.
  • Model 202: The Model 202 UV light meter is a dual channel meter, i.e., channel A at 365nm and channel B at 400nm.  Measurement range from 1.00 MW/CM2 to 19.999 W/CM2 (20W/CM2) in two scale positions.
  • Model 220:  The Model 220 measures both MW/CM2 and MJ/CM2 in a range from .01 to 19,999.  In the MJ/CM2 function, a selection switch allows for either single pulse or accumulated value.
  • Model 221: The Model 221 measures both MW/CM2 and MJ/CM2 in a range from .01 to 199.99 or 1 to 1,999. In the MJ/CM2 function, a selection switch allows for either single pulse or accumulated value.
  • Model 222: The Model 222 is designed for use with the Ember 3d printing system. The Model 222 measures both MW/CM2 and MJ/CM2 in a range from 1.0 to 199.99. In the MJ/CM2 function, a selection switch allows for either single pulse or accumulated value.
  • Model 325  Model 325 measures MW/CM2, peak MW/CM2, MJ/CM2 (single pulse), accumulated MJ/CM2, time (single pulse), and accumulated seconds. The Model 325 can operate in the single channel mode or dual channel mode.
  • Model 410 The top of the line light meter measuring MW/CM2, MJ/CM2, time, and calculating light uniformity in a number of measurement situations, Model 410 is a light measurement instrument with diverse capabilities. A built in computer allows Model 410 to store sensor readings and calculate average values, percent deviations and other data values.

Additional Light Meters for other Applications

  • Photometer LM-100: This meter read outs in Footcandles or 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. Read out is in watts per square meter (W/M2).

See our Light Meter Comparison 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.
