Silicate Tester

I. Product Overview

The laboratory trace silica analyser is used to determine trace silicate ions in sample water. It is widely used in power plants, chemical and fertiliser plants, metallurgy, environmental protection, pharmaceuticals, chemical fibre and semiconductor industries for the determination of soluble silica in demineralised water, steam condensate and boiler water. It is designed and manufactured with reference to 《GB/T 12149-2017 Determination of silicon in industrial circulating cooling water and boiler water》.

II. Measuring Principle

The analyser measures by photoelectric colorimetry. At pH 1.1–1.3 the soluble silica in water reacts with ammonium molybdate to form a yellow silicomolybdic complex, which is then reduced to silicomolybdenum blue by ammonium ferrous sulfate solution. The silica content is determined with the analyser. According to the Lambert-Beer law, when a beam of monochromatic parallel light passes through a coloured solution part of the light energy is absorbed by the solution; if the layer thickness is constant, the degree of absorption (absorbance A) is proportional to the concentration of the coloured substance in the solution.

III. Applications

Suitable for determining silica in sample water. Widely used in power plants, chemical and fertiliser plants, metallurgy, environmental protection, pharmaceuticals, chemical fibre and semiconductor industries for the determination of soluble silica in demineralised water, steam condensate and boiler water.

IV. Key Features

1. 7-inch colour touch screen with Android smart operating system for a better interactive experience and smoother operation.

2. Peristaltic pump continuous automatic sampling: flow-through measurement is not limited by the number of samples, allows continuous multi-sample testing and saves reagents and consumables.

3. Wi-Fi connectivity for fast wireless upload of measurement data.

4. Custom-wavelength, highly stable LED cold light source for more stable data, low power consumption and long life.

5. Preset standard curves and user-defined curves in one instrument, supporting both standardised rapid testing and individual method development for an efficient, flexible workflow.

6. Professional dust cover protecting the peristaltic pump and tubing.

7. Intelligent constant-current voltage regulation with automatic light intensity adjustment and calibration; no light source drift during long continuous operation.

8. Built-in high-speed thermal printer that automatically prints the test report when measurement is complete.

9. 16 GB storage capacity with room for 5 million measurement results.

10. Data cloud platform for long-term storage of results, short- and long-term review and analysis, and assisted management.

11. Direct data copying to a USB drive through a standard driver-free USB port.

12. Self-cleaning function: the tubing is automatically rinsed after measurement.

13. Optional built-in lithium battery power supply.
