Solarmeter® Model 7.5 ERY Radiometer

Handheld Digital UV Radiometer with Integral Sensor

• Monitoring UV Lamp Intensity and Aging 
• Monitoring Instantaneous UV in W/m2 
• Monitoring Tanning Lamp Output Regulations 
• Measuring Solar Intensity in W/m2 
• Testing Window Tint / Film Transmission 
• Testing Acrylic Shield Transmission

Silicon Carbide (SiC) Photodiode in hermetically sealed UV glass window cap. Interference filter blocks UV above erythemal response as shown on Spectral Sensitivity Graph.

Meter Operation
To operate your Solarmeter, aim the sensor window located on the top panel of the meter directly at a UV source. Press and hold the push-button switch on the face of the meter. For best results take note of the distance the reading was taken from the UV source in order to ensure repeatable results.

Battery operation voltage is viable from 9V down to 6.5V. Below 6.5V, the numbers on the LCD display will begin to dim, indicating the need for battery replacement. Under typical service load, a standard 9V battery will last approximately 2 years.

Proper Usage of Solarmeter® D3 Radiometer
• Wear eye protection when checking UV lamps (Glasses that provide wrap around protection are ideal).
• Allow lamps to warm up prior to taking readings (at least 5 minutes). 
• When checking lamp aging, make sure to use the same location and distance to ensure accurate readings. 
• Lamps should be replaced when output drops to about 70% of their original (new) readings. 
• To take the overall reading at the center of the tanning bed, place meter pointing up with canopy closed. 
• To take readings at body position, hold the meter about 25cm above the bench with canopy closed.

Acrylic Testing
• For acrylic testing, take readings with and without acrylic at a fixed distance.
• When comparing different types of lamps consider readings to be relative rather than absolute.

• 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.
