Solarmeter Model 8.0 UV Meter UVC

Features

• Integral Sensor
  
  
• Compact
  
  
• Durable
  
  
• Accurate
  
  
• LCD readout
  

Applications

• Lamp UVC Intensity & Aging
  
  
• Eye wear UV block comparison
  
  
• UVC Lamp Box Leak Check

Sensor/Detector
Silicon Carbide (SIC) Photodiode packaged in hermetically sealed UV glass window cap.
Interference filter blocks UVA and UVB from response as show on Spectral Sensitivity Graph.

Operation
Press and hold push-button switch on face of unit. Aim sensor window in top panel of meter directly at UV source. Note reading on LCD and record if desired.

Battery operation voltage is 9V down to 6.5V. Below 6.5V the LCD numbers will begin to dim, indicating the need for battery replacement. Under "typical" service load, the battery should last about 2 years.

Proper Usage of Solar meter Ultraviolet Radiometer for Lamp Tests

• Wear UV-block eye, face, hand protection when checking UVC lamps.
  
  
• Allow lamps to warm-up prior to taking readings (at least 5 min).
  
  
• Hold sensor close to lamp to measure individual lamp UVC intensity. Hold sensor at distance from lamp(s) for effective sterilization intensity.
  
  
• When checking aging of lamps, keep measuring distance and locations constant.
  
  
• Lamps should be replaced when output drops to about 70% of their original (new) readings.
  
  
• If unsure of what original new values were, replace a lamp with new one and compare old one.
  
  
• Do not subject the meter to extremes in temperature, humidity, shock or dust.
  
  
• Use a dry, soft cloth to clean the instrument. Keep sensor free of oil, dirt, etc.
