Introduction
This instrument features 16 channels for the optical method and can measure over 60 parameters, as well as PH, conductivity, TDS, salinity, dissolved oxygen and water temperature by the electrode method. Users can freely combine as needed. The instrument is equipped with a dual-temperature-controlled digestion device and contains a large-capacity lithium battery, which can be used for water quality testing in on-site environments without power supply. The products are widely applicable to fields such as scientific research, universities, sewage treatment, water environment testing, self-inspection of enterprise sewage, drinking water, surface water and groundwater testing.
Product Features
1. It can detect the concentration, absorbance and transmittance of nearly a hundred parameters
in water quality, and can store, print, query and upload the concentration values to the computer.
2. The instrument is equipped with an 8-hole dual-temperature zone digestion device, featuring a 4+4 dual-temperature zone design with independent temperature control, making it suitable for multi-index and batch project testing.
3. The electrode method and spectrophotometry are integrated into one, meeting the multi-item:
parameter testing requirements of electrochemical method and colorimetric method.
4. Three-proof chassis: Dust-proof, water-proof, and shock-proof. Integrated equipment, covering
all the needs of outdoor water quality testing. Easy to use and portable.
5. Outdoor detection eliminates battery life anxiety. Continuous dual-temperature digestion can
last up to 3 hours, supports simultaneous digestion of multiple parameters, and the main unit's
battery life can reach 48 hours.
6. It can store 200 factory curves, add 3,000 user curves, and store up to 99,999 records.
7. The LED light source responds quickly, the instrument can be used immediately upon startup,
and the measured values are stable and reliable.
8. It has a one-click recovery function. When the factory curve and user curve data records are lost
due to an accident, one-click recovery can be achieved.
9. The instrument can take backup measures for the curves and data records calibrated by the
user. In case of unexpected loss, recovery operations can be carried out.
10. The instrument is equipped with a large-screen color touch screen, featuring a user-friendly
operation interface and an operation guide that explains the operation of various functions.
11. Personalized and free customization. Detection parameters and measurement ranges can be
customized and upgraded according to requirements.
12. The instrument is equipped with various security measures. It can be set to enter passwords
for startup and system Settings to prevent other personnel from making incorrect operations on
the instrument Settings.
13. The light intensity is adjustable, divided into 16 levels, and can be set arbitrarily, which can
effectively solve the problem of measurement range expansion caused by the strength of the
signal.
14. Support optical calibration to ensure the accuracy of optical components, enhance the
precision, stability and service life of the instrument;
15. It can store up to 100,000 records (including parameter names, concentrations, units,
detection times, operator numbers, etc.). When querying records, single-item printing or page
printing can be performed.
16. Curve query is possible. Besides querying the curve equation, the standard value of each
standard substance during calibration, the corresponding absorbance, the calibration time and the
calibration personnel number can also be queried, fully reproducing the state at the time of
calibration.
17. The system has a bilingual function and can switch between Chinese and English.
18. It has a USB port and can transfer data to a computer.
