Difference of LS116 Transmission & LS117 OD Meter
Recently, many customers asked aboutdifference of LS116 Transmission Meterand LS117 Optical Density Meter,customers thought that two types of instruments are for lighttransmittance ratio test, How todetermine which instrument is more suitable for testing their own products’material?
In fact, this problem is easy to solve, forexample, when we need to find test transmittance instrument, we may do not understand the instruments, however, At first, we must understand own need totest what kinds of material.
First, understand clearly about each material performance that need to test, and the materials testing parameterinformation needs, like this will be faster help us find suitable instrumentfor test. Customers that consulted with Linshang, should all know, in theprocess of consulting, customer service will try to understand clearly of needfor test materials. Because there are a lot of instruments, the appearance andthe parameters looks same, but the actual application of the industry and thecorresponding test material is different.
So in order to avoid customers choose thewrong instrument, avoid the ascension of the exchange rate, The customers whois in search of an instrument and do not quite understand test product materialwell, can directly send the samples to our customer service, it will be fasterand more efficient to find the appropriate test instrument.
In addition, in view of the problems mentioned above, the difference between LS116 transmittance meter and LS117 Optical Density Meter? The main points below can help us see the difference:
1, Can be tested material is not same:
LS116 transmittance meter is for testing smooth transparent, surface cannot be matte, mist, like PMMA, PC, such asplexiglass can choose light LS116 to test their transmittance.
LS117 optical density meter can be tested surface is frosted, mist, like a lampshade, film, and some of the dark color ofthe materials can choose ls117 optical density meter to test theirtransmittance.
2, Light source is different:
LS116 light transmittance meteruse of paralleloptical design principle, with visible light 380-760nm white light source.
LS117 optical density meter use slowreflection test principle, with visible light 380-760nm in the visual sense ofthe highest 550NM wavelength, the light source is consistent with the ANSI/ISOvisual standard.
3, The test function is not the same:
LS116 transmittance meter can only test thetransmittance, the error is ±1%.
LS117 Optical Density Meter that can test the transmittance value, can also test the optical density value, the two testvalues are also displayed. The error of the two test values is not the same,the specific information can refer to the product information.
Resolution: 0.0005% Transmission / 0.01OD；
±0.02（0 --- 2.00 OD）
±2%（2.00 ---6.00 OD）
Light transmittance resolution：0.0005%
±1%（0% --- 50%）
±2%（50% --- 100%）
4, The appearance is not the same:
LS116 Transmittance Meter and LS117 Optical Density Meter can be used to refer to the product information.
Based on the above information, can bedetermined that for the same material, if you use the LS116 Light Transmission Meter and LS117 Optical Density Meter to test the transmittance, then the two transmittance value is absolute deviation
