Sensor
Silicon Carbide (SIC) Photodiode packaged in hermetically sealed UV glass window cap. Interference filter coating (Metal Oxide) blocks most UVA from response as shown 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. For reptile lamps also check at basking position.

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 Solarmeter Ultraviolet Radiometer for Lamp Aging Tests
  • Wear eye protection when checking UV lamps (UV-block wrap around glasses).
  • Allow lamps to warm-up prior to taking readings (at least 5 min).
  • When checking aging of lamps, keep measuring distance and locations constant.
  • Lamps should be replaced when output drops 30% to about 70% of their original (new) readings. Take overall reading at exposure distance, or check individual lamps close to surface. Keep track of hours vs. readings on a chart.
  • If unsure of what original new values were, replace lamp(s) with new ones of the same kind and compare to old ones.
  • To determine percent UVB divide Model 6.2 reading by Model 5.7 total UV (UVA + B) reading. (See FAQ page).
  • When checking UVT acrylic transmission, take reading through acrylic; then remove acrylic and hold meter sensor at approximately the same distance from lamp as the acrylic shield was located. If acrylic blocks much UVB it should be replaced.
  • When using this meter to compare different type lamps, due to their different spectral power distributions, the readings should be considered relative rather than absolute. Although higher output lamps of similar SPD's will generally read higher than lower output lamps, ones that peak near 290-300 nm (as does the meter response) will read higher than ones peaking near 313 nm even if the total UVB output of both is the same.
  • Do not subject the meter to extremes in temperature, humidity, shock or dust.
  • Use a dry, soft cloth to clean the intrument. Keep sensor free of oil, dirt, etc.

Proper usage of Solarmeter Ultraviolet Radiometer for Outdoor UV Index Measurement
The instrumentation used to measure UV index for the U.S. E.P.A./NWS program is directed toward the sky in a global normal (perpendicular to level ground) inclination. Therefore the Solarmeter Model 6.5 is designed to operate in the same fashion. Solar irradiance measured this way includes direct (reduced by cosine law depending on solar zenith angle) plus diffuse (diffused by the atmosphere).

This vertical (global) reading represents an average intensity value your body will experience while being active on a tennis or volleyball court, or lying flat on a blanket on the grass. If however, you are reclined in a lounge chair facing the sun perpendicular to the sun angle, you will experience a higher UV intensity, as represented by pointing the Solarmeter directly at the sun. This value will typically exceed the actual UV index number.

To obtain the UV index instantaneous value, the following instructions will provide the most consistent, accurate results:

  • Stand clear of buildings, trees, etc. to obtain a "full sky" field of view.
  • Hold the meter vertical out in front of your body.
  • Press and hold button on front of meter case. Note reading on LCD. This value represents the instantaneous UV index.
  • The highest UVI values typically occur when the sky is a deep blue color, and sometimes when the sun is between scattered white "puffy" clouds. Take extra precaution under these conditions to reduce sunburn potential.


Note that various cloud and haze conditions reduce the UV index. When partly cloudy, take readings often and average clear with cloudy readings to correlate with actual UV index. Take care in hazy or slightly overcast conditions because although the direct UV reads less than when sky is clear, the diffuse UV can be higher... as seen by pointing the meter in various directions.

Among the outdoor variables affecting UV intensity are:
  • Seasonality/Sun Zenith Angle
  • Location/Latitude/Geography
  • Reflective Surroundings
  • Altitude
  • Weather conditions
  • Ozone Layer Thickness


By regularly using the Solarmeter you will become very informed of damaging UV levels in many and varied conditions. This knowledge, along with following the outdoor precautions mentioned above, should help enable you to avoid sun damage.

Note: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.

Light Measurement

A small range of devices to measure the light and varying UV outputs of bulbs. These can be useful for keeping an eye on how your UV tubes or compact UV's are performing over time. These items can be pointed at the UV tube at various ranges to determine its effective range. This makes them a great tool for professional reptile keepers and can help you get the most out of your UV lighting.
