Overview
WGZ-20B Portable Turbidity Meter is an instrument of INESA brand for measuring the scattering and attenuation of light generated by insoluble particulate matter suspended in water or transparent liquid, and can characterize the content of these suspended particulate matter by Basis Weight. It is widely used in water plants, food, chemical industry, power plants, metallurgy, environmental protection, beverages, wine and other industries, and is a commonly used laboratory instrument.
Features
1. Adopt microcomputer technology, low power consumption configuration, touch keyboard, backlit LCD display
2. LED Infrared source, battery powered and USB powered, with automatic power-off power saving function
3. Scattered-transmitted light measurement principle, ratio calibrated
4. Automatic range switching, support multi-point calibrating
5. With average measurement function; can store 2000 sets of test data, data can be saved, printed, uploaded
6. Time, date, sample name, user name setting function, in line with GLP specifications and ISO7027 industry standards
7. USB communication interface, support connecting to PC for data upload
Principle
Using the scattering-transmission light measurement principle, the sample was irradiated with an LED Infrared source (860nm wavelength) to measure the degree of light scattering and attenuation of suspended particulate matter, and the ratio calibration method was used for quantitative analysis.
Applications
Water plant, food, chemical industry, power plant, metallurgy, environmental protection, beverage, wine making
Standards
GLP specification, ISO7027 industry standard
Steps
1. Prepare the sample bottle (< unk > 25mm × 65mm) and the sample capacity is 20ml-30ml.
2. Power on with 4 AA alkaline batteries or 5V/USB power supply
3. Set the time, date, sample name, and user name through the touch keyboard
4. Select measurement unit (NTU, FTU, EBC, ASBC)
5. Perform 2 point calibrate
6. Start measurement, the instrument automatically switches range
7. Data is automatically stored (up to 2000 groups), which can be uploaded through the USB interface or printed by connecting to an optional printer
Notice
• Make sure to use the specified size sample bottle (25mm × 65mm) and sample capacity (20ml-30ml)
Periodically calibrate instruments to ensure measurement accuracy
• Pay attention to battery power, low power consumption design with automatic power failure function
• Be careful not to exceed the 2000 group limit when storing data
• Make sure the voltage is 5V when connecting to the PC using the USB interface
• Keep the instrument clean and avoid direct light on the LCD screen
