Product overview

Turbidity is the degree of hindrance that occurs when a suspended substance in a solution passes through light. Water contains mud, dust, fine organic matter, zooplankton and other microorganisms such as suspended solids and colloids can make the solution appear turbidity. The turbidimeter (turbidimeter) measures the principle of scattered light in the direction of 90° according to the ISO 7027 international standard. When a parallel beam of light from the light source passes through the solution, part of it is absorbed and scattered, and the other part passes through the solution. When the light hits the liquid surface, there is a certain correlation between the incident light intensity, the transmitted light intensity, the scattered light intensity ratio and the water sample turbidity, and the transmitted light intensity, the scattered light intensity, and the incident light intensity are determined. The ratio of transmitted light intensity to scattered light intensity determines the turbidity of the water sample.

The ZDK-310 online turbidity analyzer has a built-in microprocessor with advanced configuration and powerful functions. It is a very accurate on-line turbidity measuring instrument. The 880-nm infrared light source penetrates through the optical lens and penetrates the sample fluid, and is measured according to the ISO 7027 international standard. With the principle of scattered light in the 90° direction, the turbidity analyzer can measure the turbidity of raw or purified water in various places of filtration devices, such as drinking water, various production and industrial waters, and any places that require the use of qualified water. . This product is compact in structure, built-in backlit LCD screen, data memory, relay control output (3 channels). The ZDK-310 turbidity controller outputs a 4 to 20 mA isolated signal, which transmits reliable data for any place where turbidity needs to be monitored and controlled.

Can be widely used in thermal power, chemical fertilizers, metallurgy, environmental protection, water treatment, pharmaceuticals, biochemical, aquaculture, food, beer, tap water and scientific research institutes and other occasions on-line continuous monitoring of turbidity.
