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

Equipment function: 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: Imported standard cotton wick cotton rope smoke alarm test

The imported standard cotton wick burns for a long time , the smoke is uniform , the smoke rise rate and particle size can be adjusted , and the cost of consumables can be reduced .

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.

Q: CO alarm calibration chamber

Equipment Function ： The equipment is intended for gas alarm or Carbon monoxide alarm testing and calibration in mass production in advantage of its big volume. The equipment provides a sealed stainless-steel chamber with glass wall for monitoring alarm status. The special designed big open door can close and secure easily without gas leakage. The volume of chamber and size of samples shelves are custom-made. It can hold 100 alarms normally. The controller injects quantitative high concentration gas into chamber and the gas stirred by circulating fan to get homogeneous test gas in certain concentration. That gas will be test gas for response test or threshold setting of gas alarm product. The circulating fan and porous plate are also specially arranged to get uniform test gas and avoid the high concentrating gas getting into alarm directly during gas injection. On the top of chamber, the inlet and outlet and exhaust fan are controlled by PLC to exchange air in chamber. Component ： CH4/CO gas controller Set the gas volume and inject gas with precision control. The gas was injected in to chamber in short time and mix quickly. It is easy to count response time of alarm Control precision: +/-5ppm CH4/CO alarm test chamber. 1）Stainless steel chamber with glass windows. 2）samples shelves, can fit with customized adaptor to connect with alarm for power supply or signal transmission 3）Chamber size: 1.8*1.0*0.8m 3.Gas analyzer, CO or CH4 (customer provide or quote additionally)
