Solarmeter® Model 7.0 UV In MED/hr.

Sensor/Detector

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

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 around 2 years.

Proper Usage of Solarmeter® Ultraviolet Radiometer Radiometer for Lamp Tests

• Wear UV-block eye protection when checking UV lamps.

• Allow lamps to warm-up prior to taking readings (at least 5 min).

• Hold sensor close to lamp or acrylic to measure individual lamp MED intensity. Hold sensor at 25 cm above bench with canopy closed for body position reading. Te (Time to 4 MEDs in minutes) = 240 / MED/hr reading.
