What is intrinsically safe(IS) radio?

For industrial and manufacturing companies, intrinsically safe equipment minimizes the risk of explosion or fire. But the workers’ main means of communication is the radio, so an intrinsically safe radio is necessary.

We have two intrinsically safe radios, RT56 and RT56B.

RT56 and RT56B radio

The right radio is RT56B, and the left one is RT56. They look different with different features, so let’s talk about more information about these 2 explosion-proof radios.

The explosive-proof grade is Ex ib IIB T4 Gb. It means the radio can operate in explosive gas and dust and can withstand temperatures up to 135 degrees Celsius.

RT56 explosion-proof radio with a small screen and keyboard.

The main features are:

  • UHF&VHF frequency band with dual-band watch and standby
  • IP65 dustproof and waterproof
  • 128 channels
  • FM radio
  • Local and remote emergency alarm function
  • VOX function
  • ANI identification code
  • Torchlight
  • Fell alarm function

So, it is very suitable for engineers and technicians who are always used in explosive workplaces. And for workers, we suggest RT56B radio.

The no screen and keyboard explosion-proof radio RT56B is very suitable for workers who are working in explosive workplaces. Because it’s more sturdy than RT56, and it can reduce the errors for workers.

The main features of RT56B are:

It is an FRS license-free radio with 22 channels.

The remote stun/kill function can protect your call safety enough.
