TWS-1600-Single-parameter Water Quality Analyzer

TWS-1600

[Product Overview]

The single-parameter water quality analyzer is a specialized instrument designed to measure specific parameters in water. It is widely used in environmental monitoring, water treatment, industrial production, agricultural irrigation, and scientific research. The core advantage of the single-parameter water quality analyzer lies in its focus and expertise. With a relatively simple structure, these instruments are easy to operate, making them accessible even to non-specialists. They can quickly and accurately provide water quality data, enabling users to promptly understand the water conditions and take appropriate actions.

Functional Features

 

    Can detect concentrations, absorbance, and transmittance of nearly a hundred parameters in water quality, and can store, print, query, and upload concentration values to a computer.


    Measurement wavelength can be selected.


    Can store 200 factory curves, add 3000 user curves, and save 99,999 data records, with data retention even when powered off.


    Instrument measurement methods can be selected as linear or piecewise methods. Choosing the piecewise method allows for more accurate measurement of 

parameters with less linear characteristics.


    Has a one-key restore function to recover factory and user curve data records in case of accidental loss.


    The instrument backs up user-calibrated curves and data records. In case of accidental loss, recovery operations can be performed.


    Features a large-screen color touch screen with a user-friendly interface, including operational guides to explain various functions.


    Light intensity is adjustable in 16 levels, freely configurable to effectively address measurement range expansion issues caused by signal strength.


    Can store up to 100,000 records (including parameter names, concentration, units, detection time, operator ID, etc.). During record queries, single-item or page printing can be performed.


    Allows for curve queries, including not only curve equations but also standard values of each standard substance used during calibration, corresponding absorbance values, 

calibration time, and calibration operator ID, fully reproducing the state during calibration.


    The instrument has various safety measures, with startup and system setting requiring password input to prevent incorrect operation by unauthorized personnel.


    The system features bilingual functionality, allowing switching between Chinese and English.


    Equipped with a USB port for data collection to a computer.
