Ultraviolet radiation has some uses and benefits in different applications. It is used in sterilization of equipment and products, in conducting experiments and a lot more.

In reptiles, ultraviolet radiation (UVA and UVB) are essential for their health as it is responsible for calcium synthesis and some important behaviors.

The importance of UV to humans and animals cannot be overemphasized and so also are the negative effects and so to ensure that you stay within safe limits, and give your pet enough exposure to stay healthy you need a UV meter.

Too much exposure to UV at work or from activities can lead to a number of health problems ranging from mild to severe.

Overexposure is the cause of the bad effects manifesting but with a good UV meter, exposure can be monitored and controlled so you can stay healthy.

You can also give your pet reptile adequate amounts of UVA and UVB necessary for healthy living with a meter that allows you to take measurements.

The presence of UV meters is high due to the need to constantly check UV exposure and amounts and so making the right choice can be difficult.

That is why we have this product review and buying guide ready for you to help you make the right choice so your purchase will give you satisfaction.

Complete Guide for Best UV Meters

UV meters are used to measure the amount of UV you are being exposed to and are necessary to ensure that your exposure to ultraviolet radiation is within safe limits.

We get exposed to some amount of UV radiation from the sun and due to occupation.

In order to avoid the harm that comes with overexposure, it is necessary to monitor and take safety precautions.

Negative Effects of UV on Humans

1. Causes Skin Cancer

The UV radiation is a known carcinogen and it is the most common cause of cancer in the environment. Overexposure to sources of UV including the sun can lead to skin cancer.

2. Sunburn

Long hours in the sun causes sunburn due to the absorption of radiant energy by your cells from the UV rays. This energy absorption causes the destruction of cells leading to ncreased blood flow to the area to attempt to repair the damage. That is why the area of sunburn appears red.

3. Damage To The Immune System

Overexposure to UV radiation has a suppressing effect on the immune system and depending on the level of exposure, can cause damage. This leaves the body defenseless against diseases and infections in the long run.

4. Causes Damage To The Eyes

Exposure to high amounts of UV or prolonged exposure to UV can cause damage to the tissues of the eye. Exposure to sunlight which is a source of UV increases your chances of getting cataract which can ultimately lead to blindness if left untreated. It is never too late to start protecting your eyes as the damaging effects of UV on the eyes is cumulative.

5. Causes Skin Aging

Long exposure to the damaging effects of UV speeds up skin aging. This is because UV destroys collagen and connective tissue under the skin, causing wrinkles and loss of skin elasticity.

Effects of UV on Reptiles

In the wild, reptiles get the spectrums of UV (UVA and UVB) from the sun. When kept as an indoor pet your reptile can no longer benefit from the sun and so other means of providing UV have to be made.

Ultraviolet radiation is very important to the health of your reptile pets because;

  • UVA is necessary for your pet’s behaviors like feeding, mating, and diurnal movement to be regulated.
  • UVB allows your pet to synthesize vitamin D3 which is important in the absorption of calcium. This will allow your pet to grow strong bones and shells (tortoise and turtles) and to have better joint movement. Without UVB any calcium supplement fed to your pet reptile would be a waste as it won’t be absorbed. Deficiency in calcium will set in and metabolic bone disease will follow.
  • UVC is not necessary for the healthy life of your pet reptile but it can help keep them free from bacteria. Be careful as high levels of exposure to UVC can be harmful.

Different sources of UV bulbs for your pet can be gotten from the store and each has different amounts of UV emission.

It is important that you know the levels of UV the bulbs you purchase emit so you can be sure your pet is getting good enough quantity.

The amount of UVA and UVB depends on your type of reptile and it is important that you know this amount so you can ensure your pet suffers from no deficiency.

Desert reptiles being used to high amounts of sunlight do require more amount of UV light. So if your pet reptile is native to desert areas, you should go for a UV bulb that gives off 12% UVB and plenty of heat.

Rainforest reptiles do not need as much UV to be healthy and synthesize the amount of vitamin D3 they need. At 5 – 7% of UVB they are good to go.

These sources of UV diminish in their outputs over time and so it is important to measure it using a UV meter at intervals to be sure that what it gives is still helpful to your pet.

Things to Look Out For In a Good UV Light Meter

What separates the best equipment from others are a few factors that are part of the device.

Putting these factors into consideration when making a purchase will help you get the most out of your money.

Measurement Range: Minimum Reading to Maximum Reading

If the device is not sensitive at low intensities, the readings obtained can be very noisy.

The readings will have great variations or the device will provide no readings at all in the presence of noise so it has to be avoided. 

An over-sensitive device can also saturate and miss peak readings leading to errors in peak and total integration. To avoid these from your meter, avoid noisy readings and saturation.

Reviews on products can give you information on these and help you make the right choice.

ISO17025 Accredited and NIST Traceable Calibration

The device should have a calibration that is accurate even when tested on other systems.

If your device is ISO17025 accredited then you can be sure of quality calibration as annual audits of the calibration facility are compulsory before this accreditation is given. So check for this accreditation on the product before purchase.

Data Storage

A device that allows you to store data on it saves you time in the event that you have to consult previous readings.

Heat Stability

During measurements, the UV meters get exposed to heat and this has both long and short term effects on the device.

In the short term, the readings can increase or decrease when the device heats up and in the long run the life of sensitive components of the device could be shortened.

So you need to choose a meter that will last long and also provide you with accurate readings even if exposed to heat. 

Commonly Asked Question About UV Meters

Q: What Instrument Is Used To Measure UV Index?

Spectrophotometers are used to measure the UV index. They measure the intensity of radiation over a spectral range at a large number of discrete wavelengths.

Q: Do Clouds Block UV?

Yes, clouds do block UV, especially UVB.

Q: Are There UV Rays At Night?

UV rays are part of the white light from the sun which does not reach earth at night. The rays are not completely blocked at night but are present in little amounts.

Q: Why Is UV Dangerous?

The sun is the natural source of UV and this radiation is shielded from the earth by the ozone layer. Overexposure to UV can lead to skin cancer, damage to the eyes and low body immunity.
