URALSEMICONDUCTOR RESEARCH CENTER

The Uralsemiconductor Research Center is a leading photonics enterprise specializing in the development of optical instruments; it has been developing and manufacturing analyzers since the 1990s. Its first customers were power generation companies, including Russia’s largest thermal power plants (Permskaya, Surgutskaya-2, and Kostromskaya). Since 2003, the company’s turbidity meters have been incorporated into construction and modernization projects for water treatment systems in accordance with guidelines issued by OJSC VTI. Recently, nuclear power plants and customers in Belarus have also begun purchasing these instruments. Uralsemiconductor’s devices are used across many industries that rely heavily on water. Here, we present the company’s top products.

OVER 600

liquid turbidity meters have been manufactured since 1990. They are designed for operating conditions in the Russian Federation and function reliably amidst significant optical and electromagnetic interference. They are used in process control for water treatment and recirculating water supply systems, as well as for drinking water monitoring. They are successfully employed at chemical plants and nuclear power stations.

over 6000
photodetectors and more than 200 photodetector modules have been supplied to industrial enterprises. Photodetectors based on thin films of ultra-pure CdPbS and PbS are unmatched in terms of stability and service life (10–30 years). These include photodetector modules designed for the 0.22–3.6 µm range, featuring thermoelectric (TEMO) cooling.
We offer 3 basic types of devices:
1. The SShR-91/5 is a dual-channel turbidimeter designed to monitor sludge levels (sludge blanket detection), with a range of 20–1000 mg/L. It features a 13 mm optical path length (cuvette length). Three versions are available for the flow-through cuvette and two for the electronic control unit. The turbidimeter operates on the transmitted light measurement principle, ensuring superior accuracy.

2. The AZhT-94/4 is a turbidimetric analyzer for suspended particles in liquids, covering a range of 0.3–200 mg/L; it is available in four versions with optical path lengths ranging from 30 to 150 mm. It is equipped with an automatic optics cleaning system with selectable intervals of 15, 30, 60, or 120 minutes. Calibration accuracy against turbidity reference standards (GSO) is 2.5%, while optoelectronic (differential) accuracy is better than 0.3%.

3. The AZhN-98/PK is a nephelometric liquid analyzer featuring four measurement ranges spanning 0.1–1800 mg/L. The nephelometer measures light scattered by particles suspended in the liquid.

*Options for the AZhT-94/4 and AZhN-98/PK analyzers: pressure regulator, micro-bubble removal chamber, and sample stream selector (4 channels).
