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.
