Transmitting opaque smoke detector filter
With the vigorous development of China's national economy, environmental protection work in the overall environment has been urgently put on the agenda. China's motor vehicle exhaust emission standards are approaching those of Europe. The opaque smoke meter with high technical indicators for automobile exhaust detection is gradually replacing the filter paper smoke meter and entering the market.
The opaque smoke meter is a portable intelligent instrument used to detect visible pollutants in the exhaust and smoke of compression ignition diesel engines. This instrument adopts advanced measurement technology and advanced detection components from abroad, and is suitable for environmental protection departments, motor vehicle inspection stations, automobile manufacturers, automobile repair shops and other units. The opaque opacimeter filter is the core component of the instrument, which serves to approve the opacimeter.
Technical Parameters:
1、 This product is a filter developed strictly in accordance with the technical requirements of JJG976-2010 Transmission Smoke Meter and JJG976-2002 Transmission Smoke Meter. Neutral, accurate and reasonable uncertainty, easy to carry, with packaging box.
2、 The transmittance (one-way) is about 71%, 50%, and 34%.
3、 The transmittance (bidirectional back and forth reflection) is about 84%, 71%, and 58%.
4、 A set of 5 pieces.
5、 Transmittance expansion uncertainty u≤ 0.6%k≤ 2 (Requirements of the latest regulations in the above-mentioned countries)
6、 Uncertainty: U=(0.3-0.5)%, K=2.65
7、 Transmission ratio nominal range: (20≤ 22)%, (27≤ 30)%, (34≤ 37)%, (50≤ 55)%, (71≤ 80)%
8、 Fixed wavelength: 400nm-760nm
Tip: The validity period of 12 months refers to the calibration of this standard filter.
Ruicheng Optoelectronics produces standard filters for non transparent smoke meters, which are available in three piece and five piece packages. Currently, the stock is available in three piece packages, which are divided into 30%, 50%, and 70% sizes. There are also 60%, 80%, and 90% sizes available for purchase. The base material of the filter is neutral glass coating, which has strong resistance to friction and high temperature, making it highly stable in the long term. When the light weight is contaminated, it can be cleaned with optical lens cleaner or alcohol to restore accurate values. Welcome to choose
