Haze Tester FAQ


Q: What is haze and haze measurement unit?

A: Haze is measured with a wide angle scattering test in which light is diffused in all directions which results in a loss of contrast. That percentage of light that when passing through that deviates from the incident beam by greater than 2.5 degrees on average is defined as haze. So the haze unit is the percentage (%).


Q: What is transmittance?

Transmittance (T) is a measurement of how much light passes through a sample. Transmittance is defined as the ratio of the intensity of incident light: intensity of transmitted light. So the transmittance unit is also the percentage (%)


Q: What is the difference between TH-100 and CS-700 haze tester?

A: 1). Different Design

TH-100 haze meter is the vertical model. CS-700 is the horizontal model. Both of them can be placed vertically and horizontally.


2). Different Price

CS-700 haze meter is designed to compete with BYK haze meter. TH-100 haze meter is the economic model for customers who can not afford CS-700.


3). Different Inner Detector

CS-700 adopts a spectrometer as detector so it can get the transmittance curve and value at every 10nm from wavelength 400-700nm. TH-100 adopts photocell as detector and it can not show transmittance curve and value.
