G and R Labs - Model 320 MeterFeatures

  • Less than 1% Probe to Probe Repeatability.
  • Real Time Measurements.
  • Interchangeable Probes
  • Computer Interface (cable available by request)
  • Cosine response probes
  • Measures MW/CM2, Peak MW/CM2, MJ/CM2(SP), time (seconds) with Average MW/CM2 and Peak MW/CM2
  • Calculates average value, % uniformity and % deviation from center value
  • Battery operates for approximately 18 hours before recharge
  • Charger operates from 100-240 VAC, 50-60 Hz with UL, CE, and TUV approvals

The Model 324 is a simplification of the Model 400. As in the 400, a built-in computer allows storing of sensor readings and calculations of average value and percent deviations. The two line display format allows for several readings at one time. The Model 324 measures MW/CM2, Peak MW/CM2, MJ/CM2 and time (single pulse) with average MW/CM2 and Peak MW/CM2.

The Model 320 has four modes of operation. 5 point MW (MW/CM2) and 5 point MJ (MJ/CM2) allow taking five readings in a fixed pattern and then displaying the average value and the +/-% uniformity as well as the +/-% deviation from the center value.

The rechargeable battery lasts for about 18 hours and the charger operates from 100-240 VAC, 50-60 Hz with UL, CE, and TUV approvals.

A variety of sensor packages can be used with the Model 324 at wavelengths from 220nm to 540nm and beyond. Traceability to NIST is +/-3.0% with probe matching to +/-1.0%.
