Modern activity trackers have revolutionized how we monitor our health and fitness. With ever-evolving features, one of the most crucial considerations for consumers is whether the device is waterproof — a significant factor if you’re planning to swim, shower, or run in the rain with your tracker on. Two widely seen water resistance ratings on these devices are IP67 and IP68. Though they might appear similar at first glance, they offer different levels of protection.
TLDR: Understanding IP67 vs IP68 Waterproof Ratings
IP67 and IP68 are standard ratings that classify the level of protection a device offers against dust and water. IP67 means the device can survive being submerged in up to 1 meter of water for 30 minutes. Meanwhile, IP68 can go beyond those limits, often tolerating deeper water over longer durations. However, real-world durability depends heavily on manufacturer implementations, so always check the fine print.
What Does an IP Rating Mean?
The IP (Ingress Protection) rating is an international standard defined by the International Electrotechnical Commission (IEC). It classifies and rates the degree of protection an electrical device provides against solid particles (like dust) and liquids (mostly water).
An IP rating generally consists of two digits:
- The first digit refers to protection against solids (like dust).
- The second digit refers to protection against liquids (mainly water).
So for example:
- IP67 means:
- 6 – Dust-tight, offering complete protection against dust ingress.
- 7 – Protected against temporary immersion in water up to 1 meter deep for up to 30 minutes.
- IP68 means:
- 6 – Same dust-tight protection as IP67.
- 8 – Protection against continuous immersion in deeper water (beyond 1 meter), often as specified by the manufacturer.
Breaking Down IP67 Waterproof Rating
Devices with an IP67 rating are generally safe from accidental exposure to water. Whether you get caught in a rainstorm or accidentally drop your tracker in the sink, it should be able to tolerate the situation without damage.
However, IP67 is rated for temporary immersion. It’s not suitable for swimming or extended underwater activities. The depth limit is typically 1 meter, and most testing is performed in controlled, fresh-water settings — not saltwater or chlorinated pools.
Understanding IP68 Waterproof Rating
IP68 is a more advanced rating. While it starts from the same dust protection level as IP67, the major difference lies in the water protection. Here, the device should endure immersion beyond 1 meter, usually specified as up to 1.5 meters or more for 30 minutes or longer.
This makes IP68-rated activity trackers better suited for more intense water exposure — for example, showering, swimming, or running in heavy rain. However, you must still consult the manufacturer’s specifications because the meaning of “deeper than 1 meter” is not universal for all IP68-certified devices.
Some devices may survive up to 3 meters for 1 hour, while others are designed for only slightly more than 1 meter. The conditions of the test — water temperature, movement, and pressure — also influence outcomes.
Real-World Performance: What to Expect
The lab testing under which IP ratings are awarded is conducted in ideal, controlled environments. In contrast, real-world usage may involve:
- Moving water such as swimming strokes or running water from a shower.
- Salt or chlorinated water common in pools or the ocean.
- Extreme temperatures — hot tubs, saunas, or freezing weather.
These situations may cause stress beyond what the IP rating guarantees. Even if a tracker is IP68-rated, manufacturers might still void warranties for damages due to water exposure — always read the product’s warranty and user manual carefully.
Comparing IP67 and IP68: Key Differences
| Feature | IP67 | IP68 |
|---|---|---|
| Dust Protection | Completely protected | Completely protected |
| Water Immersion Depth | Up to 1 meter | Beyond 1 meter (specified per device) |
| Duration of Immersion | Up to 30 minutes | Varies, typically longer than 30 minutes |
| Swimming Suitability | Generally not recommended | Often suitable, based on specs |
| Price Indicator | $ (More affordable) | $$ (Often higher-end) |
Use Case Scenarios
Here’s how the different waterproof ratings hold up in common daily scenarios:
- Washing your hands: Both IP67 and IP68 can handle this with ease.
- Light rain: Covered by both ratings.
- Accidental drop in the sink or toilet: Both can generally survive the mishap.
- Showering: IP68 is better suited; IP67 may degrade over time with daily exposure.
- Swimming: Best stick with IP68 and check how deep and how long the device is rated for.
Is Higher Always Better?
Choosing an IP68-rated tracker may seem like the obvious choice, but that doesn’t always mean it’s the best one for your needs. Consider the following:
- Budget: IP68 devices usually cost more. If you don’t plan to swim or shower with your tracker, IP67 might suffice.
- Design limitations: Higher waterproofing may contribute to a bulkier device.
- Battery impact: Some highly sealed devices may exhibit limitations in thermal dissipation and battery longevity.
Common Misconceptions
Many consumers believe a waterproof rating means total water safety. This is not always the case. Here are a few myths worth debunking:
- “IP68 means I can take the tracker diving.” – Not necessarily. Check exact depth/time details.
- “IP ratings cover salt or hot water.” – No. These tests typically use fresh tap water.
- “Water resistance lasts forever.” – Gaskets and seals wear out in time, especially with exposure to heat and soaps.
Conclusion: Which One Should You Choose?
Selecting between an IP67 and IP68 activity tracker ultimately comes down to how you plan to use the device. If your usage involves exposure to minor spills, rain, and sweat, IP67 could meet your demands perfectly at a lower cost. However, if you’re a swimmer, shower daily with the tracker on, or expose your device to more rigorous water-based activities, IP68 is the smarter, more durable option.
Always look beyond the labels and study the specific implementation notes from the manufacturer. A serious investment in health tracking deserves equally serious research into the operational limits of the device.
Final Tips Before Buying
- Check the manufacturer’s small print about water resistance.
- Remember: water-resistant does not mean waterproof — even for IP68-rated devices.
- If you swim daily, consider purchasing a tracker specifically designed for swimmers rather than relying solely on the IP rating.
By understanding what IP67 and IP68 ratings really mean, you can make an informed, confident choice for your next activity tracker — one that aligns both with
