Features:
● DC fan speed control, with wind speed stability within 0.04 m/s when set at 0.2 m/s. Adjustable wind speed inthe test area:0-2 m/s.
● Temperature control range: Ambient to 55°C (optional:-40°C to 75°C), continuously adjustable. Utilizes matrixheating method to ensure temperature uniformity 2° C,temperature control accuracy better than 1°C, heating andcooling rate 0.5-1°C/min.
● Humidity control range: 25 -95% RH, humidification rate≤ 5% RH/min.(optional)
Equipped with:
● Optical densitometer: Wavelength range 880 nm -950nm.
o For aspirating smoke detectors: Error s + 1%/m.
o For point-type and standalone smoke detectors: Error+ (m x 0.05 + 0.02) dB/m.
● Aerosol generator and real-fire smoke generation device(including smoke generation using cotton rope, wood,polyurethane, n-heptane/toluene).(optional)
● Automatic rotating probe mounting device for alarmconsistency and orientation tests. The test sample canrotate around the vertical axis in 45° increments, with full360° rotation capability.
● Dazzling device to meet ambient light test requirements.
Smoke Injection Rate Requirements:
