The K2 Safety K-Signal is a next-generation electronic whistle designed for safety in extreme environments such as fine dust, yellow dust, or other harsh weather conditions. Instead of blowing a traditional whistle, the K-Signal uses an adjustable resonance chamber to amplify frequency, producing a powerful and penetrating sound that ensures it can be heard clearly in noisy or emergency situations.
Its slim, handheld design makes it easy to carry anywhere, while the built-in USB rechargeable battery allows convenient charging from PCs, laptops, wall outlets, or car USB ports.
The K-Signal also integrates a Morse-code-based emergency alarm system for quick distress signaling, as well as a high-intensity LED lamp, providing added visibility and safety in dark or hazardous worksites.
