SLIA-5000 SILICA ANALYZER

Quick and automatic measurement for boiler water, and trace amount of silica present in pure water.

Management of silica (SiO₂) is paramount in preventing the formation of scales. This is because scales present in turbines will reduce the efficiency of power generation, especially for thermal power plants and nuclear power plants. By combining HORIBA's many years of track records and technological know-how, the silica analyzer has been reborn with conventional stability, reliability and maintainability.

Segment: Process And Environmental

Division: Process Water

Manufacturing Company: HORIBA Advanced Techno Co., Ltd.

±2% F.S. repeatability with measurement time of 5 minutes
Capable of obtaining high-speed, and highly repeatable measurement results.
Wide measurement range
Measurement is possible from high sensitivity range of 0 to 10μg/L (ppb) to high concentration range of 0 to 5.0mg/L (ppm).
Self-diagnosis function
Self-diagnosis of operation abnormalities such as water sample or reagent supply error, calibration error, light source error, and in-cell temperature error.
Automatic calibration function
Zero calibration is performed automatically for each measurement. Span calibration can also be preset to perform at specific timings.
Automatic switching of measuring cycle
Switching of measuring cycle automatically saves energy and reagents because measuring cycle is automatically shortened when the sample concentration exceeds the set concentration level, and automatically lengthened when the sample concentration goes below the set level.
Improved operability
Equipped with color LCD touch panel.

Option	Filter for sample line (For Line 1 to Line 4)	By installing about 5 μm cartridge filter in the upstream of the overflow tank, it is possible to prevent iron rust, etc. from entering the equipment. Up to 2 filters can be built into the product. If the optional filter is selected for the product of 3 or 4 measurement points, the filter is not built into the product but is delivered individually as a single filter. If a step-down transformer is installed (power supply voltage is other than 100 V AC), a filter cannot be built into the product.
Option	Flowmeter for sample line (For Line 1 to Line 4)	By adding this, you can accurately measure the sample supply flow rate.

When installing the analyzer, give careful consideration to its special characteristics and be sure to provide an environment where the equipment can operate properly.
Take appropriate action so that no damage will occur even when the equipment no longer operates correctly due to deterioration or the operational conditions of the equipment, or any unexpected phenomenon.
