Model 325 UV Light Meter

The Model 325 UV Light Meter has an internal computer that allows storing of sensor readings and also calculates and stores average value and percent deviations by taking five readings in a fixed pattern for either MW/CM2 or MJ/CM2.

• A variety of sensor packages can be used at wavelengths from 220nm to 540nm and beyond.
• Wavelength traceability to NIST is +/-3.0% with calibration certificate provided.
• Probes are calibrated to +/- 1% to each other at the same wavelength and are interchangeable
• Dual channel probe or single channel probe capability
• Dual and single channel probes are Interchangeable with the Model 325 Cosine response probes
• Measures MW/CM2, peak MW/CM2, MJ/CM2 (single pulse), accumulated MJ/CM2 time (seconds), and accumulated time
• 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
