VicoMeter is an expert in analysis and testing, providing fast, targeted industry solutions for different users.
This instrument is widely used in emergency monitoring, industrial wastewater, domestic sewage, wastewater treatment, pharmaceuticals and chemicals, food, beverages, textile printing and dyeing, electroplating, papermaking, petroleum and metallurgy, river treatment, research institutes, universities, and other fields.
The interactive human-machine interface features prompt functions that indicate the next step, intelligently guiding users through the operation with direct readout of test results.
For each data set, the instrument measures the water sample 10 times, removes outliers, and averages the results to reduce measurement error, while flagging any abnormal results.
Mature colorimetric technology and a stable system combined with proprietary algorithms minimize the impact of dirty, scratched, or flawed glass tubes (including fingerprints) on results. Paired with VicoMeter's dedicated integrated digestion-colorimetric tubes, stability is no longer a challenge.
Equipped with one Ethernet, one USB, and one Mini USB port, the instrument easily connects to a computer for data upload, and data can also be uploaded over the LAN via the Ethernet interface, facilitating daily water quality management and analysis and providing data support for the stable operation of wastewater treatment;
The favorite programs function lets users add frequently used test programs to their user programs for quick access, avoiding the inefficiency of searching through program lists.
Built-in fast measurement and stable measurement modes allow users to freely choose between speed and accuracy.
The instrument features printing and data storage. Results can be printed immediately (optional Bluetooth printer) or printed from historical records. With built-in storage for 30,000 sets of historical test data, users can retrieve data anytime or upload it to a PC for unlimited permanent storage.
VicoMeter's integrated digestion-colorimetric tubes work seamlessly with the rapid water quality analyzer and are compatible with φ16 mm and φ25 mm cuvettes.
● Testing complies with national, industry, or international standards.

1. Multi-Channel Light Source System
The multi-channel light source system uses fixed wavelengths, eliminating the need for wavelength adjustment, with no mutual interference between light sources.
2. Integrated Digestion-Colorimetric Tube
Digestion and reading share a single tube, eliminating the need to transfer liquid into a cuvette for measurement—simple, safe, and worry-free.
3. Interference Elimination
Excellent tube uniformity and light transmittance minimize the impact of dirty, scratched, or flawed glass tubes (including fingerprints) on results.
4. Ten Measurements with Outlier Removal
Each data set is measured 10 times; after outliers are removed, the result is calculated using a dedicated algorithm to reduce measurement error.
5. Data Analysis
Sample concentration values are displayed directly, with prompts for abnormal results. Test results can be printed or stored.
6. Data Processing
Data can be uploaded to a computer via USB or LAN, facilitating daily management and analysis and providing data support for the stable operation of wastewater treatment;
