Force and mechanical measuring equipment
Hanna's EPA-compliant turbidity meters are designed to meet or exceed the standards set forth by USEPA Method 180.1 and Standard Method 2130 B. USEPA Method 180.1 specifies key parameters for the system. Optical system for measuring turbidity for drinking, brine and surface water using the nephelometric method.
In the nephelometric method, light rays passing through the sample scatter in all directions. The intensity and pattern of scattered light are determined by many variables, such as the wavelength of the incident light, particle size and shape, refractive index, and color. The optical system consists of a tungsten lamp, a scattered light detector (90°) and a transmitted light detector (180°).
The HI740234 is intended for use with EPA turbidity meters including:
HI83414 – Benchtop turbidity and chlorine meter
HI88703 – Benchtop turbidity meter
HI93414 – Portable turbidity and chlorine meter
HI98703 – Handheld turbidity meter
