The Automatic 2-in-1 Smoke and Heat Detector Testing Kit is an intelligent next-generation testing device designed for the inspection and maintenance of fire alarm detection systems. This professional testing tool combines both smoke detector testing and heat detector testing in a single integrated unit, making it an essential solution for fire safety engineers, maintenance teams, and inspection professionals. Built with anodized aviation-grade aluminium, the tester is lightweight, durable, and easy to carry, while also offering excellent corrosion resistance for long-term use in industrial environments. The device uses advanced electronic induction technology that automatically generates smoke and heat when the testing head is placed close to a detector. With its special electronic atomization smoke system, it produces clean testing smoke without soot or residue, ensuring that detectors remain undamaged and uncontaminated during testing. The tester supports maintenance, commissioning, acceptance testing, debugging, and sensitivity verification of both smoke detectors (ionization, photoelectric, and combined types) and heat detectors (fixed temperature and rate-of-rise). Powered by a 7.4V rechargeable battery, the kit delivers up to 450-800 smoke tests and more than 800 heat tests per full charge, making it ideal for large-scale inspection projects. This professional Smoke & Heat Detector Testing Kit is an essential tool for fire safety inspection, fire alarm system maintenance, and detector performance testing in commercial buildings, industrial facilities, and safety installations.
