1TW-5275 Multi parameter Water Quality Testersummary

By using narrowband filtering technology, a specific single wavelength is generated. Under the control of a high-performance microcontroller, the absorbance is measured using a ratio method. According to Lambert Beer's law, the instrument automatically calculates the concentration of the measured parameter. This instrument has a LCD display, built-in curves, a built-in printer, and a USB interface for uploading data. It is widely used in environmental monitoring, sewage treatment, large, medium, and small water plants, industrial and mining enterprises, domestic or industrial water use, colleges and universities, research institutions, and other departments.
