Product Description Product Description IntroductionERUN-ST7 Laboratory Multi-parameter Water Quality Tester. The instrument contains optical method and electrode method (pH, conductivity, TDS, salinity, dissolved oxygen and water temperature, etc.). The user can combine different parameters freely as required. Widely applicable to the determination of drinking water, surface water and sewage. Detailed PhotosProduct FeaturesFunctional Features1. 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.2. Measurement wavelength can be selected.3. Can store 200 factory curves, add 3000 user curves, and save 99,999 data records, with data retention even when powered off.4. 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.5. Has a one-key restore function to recover factory and user curve data records in case of accidental loss.6. The instrument backs up user-calibrated curves and data records. In case of accidental loss, recovery operations can be performed.7. Features a large-screen color touch screen with a user-friendly interface, including operational guides to explain various functions.8. Light intensity is adjustable in 16 levels, freely configurable to effectively address measurement range expansion issues caused by signal strength.9. 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.10. 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.11. The instrument has various safety measures, with startup and system setting requiring password input to prevent incorrect operation by unauthorized personnel.12. The system features bilingual functionality, allowing switching between Chinese and English.13. Equipped with a USB port for data collection to a computer.Technical ParametersTechnical ParametersMeasurement parameterstotal alkalinityWavelength340nm, 420nm, 440nm, 470nm, 520nm, 540nm, 560nm, 610nm, 630nm, 660nm, 680nm and 700nm (Any wavelength within the above range can be customized; pH, conductivity and dissolved oxygen can be selected as required)Indication error≤±5 %Repeatability≤2%Optical stabilityAbsorbance drift ≤0 .002A/20minDimension387mm*292mm*134mmWeight2.6kgPower30WWorking environment(1) Ambient temperature: 5~40oC (2) Relative humidity: ≤85% (3) Power supply: AC 220 (165V-240V) (4) No significant vibration and electromagnetic interference, avoid direct sunlight.
