The SignRich WGZ-2B Turbidity Meter is used to measure the degree of light scattering produced by insoluble particulate matter suspended in water or transparent liquids, and to quantitatively characterize the amount of these suspended particulate matter. It can be widely used in turbidity measurement of power plants, pure water plants, water plants, domestic (CN) sewage treatment plants, beverage plants, environmental protection departments, industrial water, wine industry and industries, departments, and other departments.

Portable, AC and DC power supply, with low Voltage indication and automatic shutdown function. The serial RS232 communication interface can be used to connect to micro printers.
The microcomputer is equipped with a low-power configuration and a touch-screen keyboard with a backlit LCD display that simultaneously displays the date, time, measured value and unit of measurement.
The measuring range can be manually selected or automatically switched. The calibration standard value can be set arbitrarily programmable, and 1-7 points can be quickly and arbitrarily selected for automatic correction.
It is equipped with an average measurement mode and a data query mode, with the functions of nonlinear processing and smoothing of measurement data, and with self-diagnosis information prompts.
The built-in clock memory storage system can store measurement and calibration data in real time, and can store and recall the last 20 sets of measurement data for a long time.
A variety of measurement modes, preset NTU, FTU, EBC, degree (Unit), ppm, mg/L, % and other units.
It is equipped with a color compensation system, which can effectively avoid the interference caused by the color of the sample and can correctly reflect the concept of turbidity.
100,000 hours long-life high-intensity light source, maintenance-free long-term use, in line with ISO turbidity measurement standards.
