Model: YH-FR-UL
This system is an integrated fire experiment platform thhat strictly complies with the US standards UL-217 and UL-268. It is suitable for sensitivity calibration and perfformance verification of smoke detectors in accordance with US standards.

System Features
● Complete Solution: Provides full-process support from
laboratory planning, hardware integration, and software control to test consumables, including installation, commissioning, and technical training.
● High-Precision Measurement: Adopts internationally
mainstream optical and ionization smoke measurement tech- nologies to ensure data accuracy and repeatability.
● Radiation Safety Compliance: The system is equipped with the DELTA EC-912 ion concentration meter, which contains a very low-activity Class V sealed radioactive source (Am-241, activity 130 kBq).
The ion concentration meter is a separately configured device and must be purchased separately. It is not included in the standard system quotation.
