When choosing a walkie-talkie, there are many aspects to consider, such as whether a license is required, power and communication distance, etc., but for some construction, mining, forestry and other professionals or professionals in outdoor activities, the waterproof performance of the walkie-talkie is also a very important factor.
To judge the standard of waterproof, it is very important to look at the IP level, IP stands for Ingress Protection, or the level of protection provided by radio enclosures. The first number after the letter P stands for “Solids Protection,” and the second digit stands for “Liquid Protection.” “Solids” include things like dust. While “liquids” define moisture of many kinds.
Here is the protection index scale for impact resistance
0: The walkie-talkie has no protection
1: Protection against solids over 50mm
2: Protection against solids over 12mm
3: Protection against solids greater than 2.5mm
4: Protection against solids over 1mm
5: Protection against dust deposits
6: The walkie-talkie is completely dustproof
Here is the IP protection rating against humidity and water
0: The walkie-talkie has no protection
1: Protection against vertically falling drops
2: Protection against drops falling at an angle, up to 15° inclination
3: Protection against rain, up to 60° inclination
4: Protection against splashing water
5: Protection against water jets from a lance
6: Protection against very powerful jets of water
7: Protection against temporary immersion: up to 1m depth for 30min
8: Protection against prolonged immersion: more than 1m deep for 1 hour
The most waterproof protection is a number 8. While the most solid protection you can get is a 6. That means the highest level of protection against liquids and solids comes from a rating of IP68. This specific rating indicates a device is completely protected against dust ingress, as well as long term immersion up to a certain pressure.
So now, do you have a preliminary understanding of the judgment of waterproof walkie-talkies? There are many models of Retevis that are IP67 grade, as well as new ham radio RA89 (the highest level IP68). which hope will have some reference for you when choosing waterproof walkie talkie.
