3. Benefits Of Ultraviolet Radiation On Reptiles

Reptile is a kind of special animal, they get this radiation from the sun is wild. They will not live well without it. However, when you keep them indoor as pets, they can not get the benefit from sunlight and that is the reason why there should be another means of UV providing. 

Several reasons make it indispensable for reptiles

UVA is mainly helpful for feeding, mating, and movement regulating. 

UVB will allow your pet to get vitamin D3 which is essential for calcium absorption. It decides your pet’s strong growth of bones and shells and great joints movement. 

Calcium supplements will be wasted without UVB. 

UVC is not needed for health but it helps to keep them away from bacteria. However, you should be careful because the high lever of UVC exposure will cause some damages.

Ultraviolet spectrum

Each type of light bulb will have a different amount of ultraviolet radiation. You should know the levels of bulbs you need to make sure your pet getting enough quantity. 

The desert reptiles usually need high amounts of sunlight, so they need more this kind of light amount. Thus, if your pet is native to the desert, the bulb giving off 12% UVB will be the best choice. 

Rainforest does not need much UV. 5%-7% UVB is good enough. 

The sources of ultraviolet radiation will decrease in their outputs through time. Therefore, UV light meters at intervals to measure it will bring many benefits for your pets.

How To Find The Best UV Meter?

uv light meters

There are some factors which are the most important features of the meter. Hence, we should consider them first before making a purchase. It happens the same in meters, we will list it up here for anyone who needs it.

  • Range Of Measurement (Minimum Reading To Maximum Reading)

Avoid the noisy reading: as you know if the systems do not have enough sensitivity at the low intensity, then the readings could be very noisy even when applying 0.

The readings might have greater variations or in the bad case, it will not provide any reading or bog errors in the readings. 

Avoid the saturation: if the device is too much sensitive, it also can saturate the miss the peak readings, then it will cause errors in peak and the total integration. 

  • NIST Traceable Calibration & ISO17025 Accredited 

Before buying UV intensity meters, you should check ISO17025 accredited to make sure the quality calibration.

As you know to have an ISO1725 certificate, the device is manually audited of a compulsory calibration facility. 

  • Storage Of Data

If you want to save time and your money, you should choose the device allowing you for storing date on and can recall the previous readings for accurate troubleshooting even with no PC. 

  • Display

uv-c meters

The graphical display is an important feature for troubleshooting, it helps to allow the fast evaluation of light to light repeatability, light performance, reflector, and the uniformity of output for appropriate repair. 

  • Heating Stability 

As you know, if the heat is provided too much, then it can make short/long term variations. The sensor might drift with large variations in temp for the short term.

Overheating the inside components through the time can shorten the sensitive optics, filters, and electronic’s life span.

A measurement coming with heat dissipation and reflective surface can helps for reducing this problem. 

Thus, you should choose the last long meter with accurate readings even in the high heat expose.  

Commonly Asked Question About Best UV Meter

1. How Does The Meter Operate?

It works by the sensor which will measure the light intensity from 250 to 400 nanometers if the source is lamps, lights, sun, and other ultraviolet radiation sources.

A meter might store around 99 recorded measurements manually. 

2. How Is The Ultraviolet Radiation Measured?

The ultraviolet radiation intensity is measured in the milliwatts / cm2 which is energy per m2 received in a second. It also is measured in the unit of mJ/cm2 which is the energy received / unit area in the given time. 

3. Are There Any UV Rays At Night Time?

No, ultraviolet light is a part of white light from the sun, hence, it does not appear at night. However, the rays are not blocked at night, it presents a little amount. 

4. Does The Glass Block UVC?

Yes, UVC light will not go through the glass.

5. What Can Be Used To Measure The UV Index?

To measure the index, spectrophotometers will do best. It measures the intensity of radiation over the spectral ranging at a large number of discrete wavelengths.
