Model: YH-FR-01
This system is an integrated fire experiment platform thnat strictly complies with the national standard GB4715 and European standards EN54-7,EN54-20,dN1suitable for sensitivity calibration and performance verification of smoke detectors according to EU and GB 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 technologies 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.

● Operating environment: temperature 15 - 35°C (23 +2°C recommended),humidity 25 - 75% RH 

● Power supply: AC 220 V, 50 Hz, 10 A
