A must for any serious reptile keeper.
With the importance of UVB for a reptiles health you can now know when a bulb needs replacing.
(Also lets you know if the makers are telling the truth) |
Solarmeter Digital UV-Meter/Model 6.2 |
On a cloudy / misty day a reading of 034 u/w cm2
Makes you think? |
We at reptilekeeping. have been breeding animals for over 20 years, this is a product that a zoo customer of ours lent us a while ago, we were that attached to it we decided to bring them to the uk market.
Needless to say he still doesn't have it back |

Here's the Tech - spec |
Proper Usage of Solarmeter ® Ultraviolet Radiometer for Lamp Aging Tests
- Wear eye protection when checking UV lamps (eg: UV-block eyewear)
- Allow lamps to warm-up prior to taking readings (at least 5 min). thermal equilibrium may take 20-30 minutes.
- Hold sensor against lamp or acrylic to measure individual lamp UVB intensity. Hold sensor at opening in bed for average 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. Take average reading at bed opening, or check individual lamps at acrylic. Keep track of hours vs. readings on a chart.
- If unsure of what original new values were, replace two adjacent lamps with new ones and compare old ones.
- When checking 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.
- Do not use meter to compare different type lamps, due to their different spectral power distributions. Although higher output lamps will read higher than low output lamps, the readings are 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 intrument. Keep sensor free of oil, dirt, etc.
