A replacement tungsten filament lamp for EPA compliant turbidity meters.
In the nephelometric method, the light beam that passes through the sample is scattered in all directions. The intensity and pattern of the scattered light is affected by many variables, such as wavelength of the incident light, particle size and shape, refractive index, and color. The optical system includes a tungsten lament lamp, a scattered light detector (90°) and a transmitted light detector (180°).
The HI740234 is used with the EPA compliant turbidity meters including:
