How Waterproof is that Unit?

How Waterproof is that Unit?

One of the first couple questions users often ask about tablets, lasers, or GNSS receivers is how waterproof it is, especially those in the Pacific Northwest!

As you can see with all the equipment that we sell, there is an internationally recognized rating provided on the specification sheets from the manufacturer.  This rating is known as the IP Rating (Ingress Protection or International Protection).  The Ingress Protection rating system is a classification system showing the degrees of protection from solid objects and liquids.  The first number refers to the protection against solid objects, normally dust in relation to testing Pocket PCs.  If the first number is 0, there is no protection provided.  A number 5 refers to limited protection against dust.  The number 6 is for total protection against dust.  The second number of the IP rating system refers to protection against liquids.  A 0 indicates no protection while an 8 indicates protection from water immersion beyond 1-meter depth for an amount of time specified by the manufacturer.

The equipment that we sell ranges from IP54 to IP68, meaning that they are protected from dust ingress ranging from “protected from limited dust ingress” to “protected from total dust ingress” for the first number.  Then protected from water ranging from as little as “protected from water spray from any direction” (or about a “foggy day”) to as much as “protected from long-term immersion up to a specified pressure (depth of water for a certain amount of time).  For example, the Arrow Gold RTK and Basic units are rated IP67, submersion 30cm for up to 30 minutes.

Below is a shortened version of the IP Rating table.

  IP #  First Digit – SOLIDS  Second Digit – LIQUIDS
  IP54  Protected from limited dust ingress.  Protected from water spray from any direction.
  IP55  Protected from limited dust ingress.  Protected from low pressure water jets from any    direction.
  IP56  Protected from limited dust ingress.  Protected from high-pressure water jets from any direction.
  IP57  Protected from limited dust ingress.  Protected from immersion between 15 centimeters and 1 meter in depth.
  IP58  Protected from limited dust ingress.  Protected from long-term immersion up to a  specified pressure.
  IP60  Protected from total dust ingress.  Not protected from liquids.
  IP61  Protected from total dust ingress.  Protected from condensation.
  IP62  Protected from total dust ingress.  Protected from water spray less than 15 degrees from vertical.
  IP63  Protected from total dust ingress.  Protected from water spray less than 60 degrees from vertical.
  IP64  Protected from total dust ingress.  Protected from water spray from any direction.
  IP65  Protected from total dust ingress.  Protected from low-pressure water jets from any direction.
  IP66  Protected from total dust ingress.  Protected from high-pressure water jets from any direction.
  IP67  Protected from total dust ingress.  Protected from immersion between 15 centimeters and 1 meter in depth.
  IP68  Protected from total dust ingress.  Protected from long-term immersion up to a  specified pressure.
