There are many brands and models of explosion-proof walkie-talkies currently on the market, but their performance is uneven, their functions are diverse, and their prices vary widely. So, where should we start to choose a suitable explosion-proof walkie-talkie?
1. Explosion-proof performance
In an environment filled with flammable gases or dust, explosion prevention work cannot be missed. The explosion-proof performance of the walkie-talkie is a prerequisite for normal production activities. It is the first and most important wall to ensure the safety of personnel. Therefore, the walkie-talkie must obtain explosion-proof certification, and the explosion-proof performance can meet the needs of the site. In addition, be sure to check the production date of the product and whether it has the 3C mark - according to the requirements of the State Administration for Market Regulation, all explosion-proof walkie-talkies produced after October 1, 2020 must obtain 3C certification before they can be sold out of the factory and used in business service places.
2. Sound quality and volume
Voice calls are the most original and core function of walkie-talkies. Clear and loud voice makes communication smooth and helps improve work efficiency. Workplaces in the energy, petrochemical, emergency firefighting, and mining industries are often filled with a lot of background noise. In high-pressure environments, high-quality voice calls are needed to ensure smooth and orderly production. Therefore, you should pay special attention to the volume of explosion-proof walkie-talkies when purchasing. Is it big enough, and does it have noise reduction technology to ensure that the sound quality remains clear even in a noisy background?
3. Communication distance
Generally speaking, walkie-talkies will not have a clear communication distance description, but the receiving sensitivity is indeed the key to determining its communication distance: the higher the sensitivity, the stronger the signal penetration ability, and the farther the communication distance. Therefore, explosion-proof walkie-talkies with higher sensitivity can ensure that call establishment and key information transmission are more timely and effective, and also provide an additional guarantee for the safety of front-line personnel and organizations.
4. Standby time
Users of explosion-proof walkie-talkies often need to work shifts, and emergency firefighters even need to be on call at any time, which is a big test for the standby time of the equipment. Therefore, when choosing a walkie-talkie, you must fully consider its battery life to avoid problems such as inefficiency and lag in response caused by frequent charging, so as to not lose the chain at critical moments.
5. Function configuration
In addition to the basic intercom function, the intercoms currently on the market have many other functions to meet the diverse needs of users. So, the more functions, the better? Not necessarily, but what is certain is that the more functions a walkie-talkie has, the higher its price will naturally be. We only need to choose the function configuration that meets the actual needs. For example, if location information needs to be reported at any time, then the positioning module must be configured; in many cases, there is no way to keep an eye on the screen to confirm the operation, so voice broadcast is very useful.
6. Protection level
If you don’t want the device to become a “brick” after being dropped or encountered in harsh environments, it is very necessary to choose a walkie-talkie that has been designed specifically and has undergone rigorous testing. The reliability of walkie-talkies is usually reflected in the IP dustproof and waterproof rating and drop resistance. Professional walkie-talkies also undergo rigorous U.S. military standard testing. Choosing an explosion-proof walkie-talkie with a high protection level allows front-line personnel to cope with complex and harsh environments with ease, without worries, and can also greatly reduce equipment maintenance and repair costs.
