Device features: The composition of paraffin oil for smoke generators mainly includes mineral oil, water and soluble powder. Among them, mineral oil is one of the main components of smoke generators, and its role is to provide volatile substances that enable oil to be converted into smoke. Water is added to reduce the risk of fire from the oil in the smoke generator, and its role is to improve the safety of the smoke generator. Soluble powders are used to increase the density and stability of smoke. The smoke produced by the smoke generator is safe and non-toxic and will not cause harm to the human body. The main components of the smoke sprayed by the fire smoke generator are water and propylene glycol, which is food-grade smoke, safe, non-toxic and residue-free. Equipment parameters: 1) Model: 500ml 2) Brand: Zhijian 3) Odor: colorless and odorless 4) Medium: light paraffin water

The aerosol generator atomizes liquid paraffin into aerosol through the nozzle. It is mainly designed for the sensitivity and function test of smoke alarm and detector. SM220 aerosol generator adopts compressed gas to atomize liquid paraffin, therefor the aerosol generator includes precision pressure regulating valve and pressure gauge and time controller. It combines two operation modes: external and internal control modes. In external control mode, the aerosol on/off is controlled by 20VDC input signal. In internal control mode, the aerosol on/off is controlled by embed timer and external 24VDC power supply. The work duration and time interval are settable on time controller. Equipment parameters: Model: SM220 Power supply: 24VDC 50W Air supply: 0.5Mpa, dry, oil free, Agent: liquid paraffin Bottle: 100ml

Q: ZNOBS110 Obscuration meter

Equipment Function ： Optical smoke density meters are mainly used to measure the concentration of smoke or aerosols. The ZNOBS110 optical smoke density meter emits transmitted light from an infrared light source through the testing area of the smoke box and reflects it into the photoelectric element. By measuring the attenuation of the photoelectric signal, the concentration of smoke or aerosol in the smoke box is measured. The intelligent inspection instrument ZNOBS110 model optical smoke density meter adopts imported components and advanced photoelectric system, which can withstand the influence of environmental temperature changes and environmental light. Zero drift and temperature drift are extremely small, and can operate stably for a long time. The ZNOBS110 optical smoke density meter is suitable for use in standard smoke detector test boxes, fire test rooms, and other applicable occasions such as EN 54-7, EN 14604, GB 4715, GB 20517, etc. Specification ： 1) Model: ZNOBS110 2) Power: 12VDC Power: 10W 3) Applicable standards: EN14604, EN54-7, GB20517, GB4715 4) Detection type: Transmitted light 5) Light source wavelength: 880nm~950nm, 6) Range: 0-2 dB/m, 7) Zero drift 0.2% F.S.
