Is IP68 waterproof better than 5ATM?

Introduction

In the world of wearable technology, waterproof ratings are essential to consider when purchasing a device such as a smartwatch or fitness tracker. Two common terms used for measuring water resistance are IP68 and 5ATM. In this article, we will explore the differences between these two standards and determine which one offers better protection against water damage.

Understanding IP68 Water Resistance

IP (Ingress Protection) ratings are used to specify the level of protection offered by an electronic device against various environmental factors, including water and dust. The first digit in the IP rating represents the level of protection against solid particles, and the second digit represents the level of protection against liquids.

When it comes to water resistance, an IP68 rating is considered to be one of the highest levels available. A device with an IP68 rating is deemed to be "dust-tight" and can withstand being submerged in more than 1 meter of water for a continuous period of time. However, it's important to note that the specific duration can vary depending on the manufacturer's specifications.

The Significance of 5ATM

ATM (atmospheres) is another unit used to measure water pressure and, consequently, water resistance in devices. 5ATM is equivalent to a depth of 50 meters or approximately 165 feet. This means that a device with a 5ATM rating can resist water pressure at a depth of 50 meters without any water ingress.

It's crucial to understand that the 5ATM rating does not indicate that a device is suitable for swimming, diving, or any other water-based activities. Rather, it implies that the device can withstand accidental water exposure, such as rain or splashes during daily use.

Which One Is Better?

When comparing IP68 waterproofing with 5ATM, it's important to consider your specific needs and usage patterns. If you engage in activities like swimming or diving, a device with an IP68 rating may provide better protection against prolonged submersion. On the other hand, if you are primarily concerned about occasional water exposure, such as during workouts or outdoor adventures, a device with a 5ATM rating should suffice.

Ultimately, the choice between IP68 and 5ATM comes down to how you intend to use your device. It is always advisable to carefully review the manufacturer's specifications and user guidelines to ensure that the device meets your particular requirements.

In conclusion, both IP68 waterproofing and 5ATM standards offer significant protection against water damage. However, the IP68 rating provides a higher level of water resistance suitable for activities involving more prolonged submersion. The 5ATM rating, on the other hand, is geared towards everyday water exposure. Ultimately, understanding your requirements and usage scenarios will help you make an informed decision when choosing a water-resistant wearable device.
