The Motorola brand is synonymous with quality in the two-way radio industry. We came across this video that shows just how tough the Tetra MTP 3000 series radio is. You wont believe what they throw at them… If you’re after a tough two-way radio be sure to look at the Ingress Protection (IP) rating or Mil Spec.

Ingress Protection (IP Rating) guide:
The rule of thumb regarding IP ratings is, the higher the number the better the protection. This guide will help you understand what IP ratings will generally protect against. IP ratings are usually represented by the letters IP followed by two digits, which indicate the protection standard i.e. IP67.

First number
Refers to protection level against solid objects.

0 – No protection

1 – Protected against solid objects over 50mm e.g. hands, large tools

2 – Protected against solid objects greater than 12mm. i.e. fingers or similar objects not exceeding 80mm in length; solid objects exceeding 12mm in diameter.

3 – Protected against solid objects greater than 2.5mm. i.e. tools or wires of diameter or thickness greater than 2.5mm; solid objects exceeding 2.5mm in diameter.

4 – Protected against solid objects greater than 1mm (0.10in) i.e. wires or similar solid material of thickness greater than 1mm in diameter; solid objects exceeding 1mm in diameter.

5 – Dust protected – dust does not enter in sufficient quantity to interfere with satisfactory operation
of equipment.

6 – Dust tight – no ingress of dust.

Second Number
Liquid resistance level.

0 – No protection

1 – Protected against dripping water – dripping water (vertically falling drops) shall have no harmful effect.

2 – Protected against dripping water when tilted up to 15 degrees – vertically dripping water shall have no harmful effect when the enclosure is tilted at an angle of up to 15 degrees from its normal
position.

3 – Protected against spraying water – water falling as a spray at any angle up to 60 degrees from the vertical shall have no harmful effect.

4 – Protected against splashing water – water splashing against the enclosure from any direction shall have no harmful effect.

5 – Protected against water jets – water projected by a nozzle against enclosure from any direction shall have no harmful effects.

6 – Protected against heavy seas – water from heavy seas or projected in powerful jets shall not enter the enclosure in harmful quantities.

7 – Protected against the effects of emersion – ingress of water in har mful quantity shall not be possible when the enclosure is immersed in water under defined conditions of pressure and time.

8 – Protected against submersion.

When purchasing a two-way radio it’s always best to discuss your needs with a two-way radio specialist to see what will best hold up your working environment.
