Reference : CRAB

CRAB is an easy-to-operate, active oil slicks optical detector. The instrument detects the presence of oil using optical sensing with a vertical laser beam and measuring the differences in the reflection properties of water and oil products.

The optimized optical scheme, signal processing routine, and modulation of the light beam intensity provide a drastic decrease of the influence of the wind waves and background illumination on the measurement results.

Features & Benefits

• Continuous remote optical sensing, no sampling
• High sensitivity: detection of oil slicks with thickness down to 0.5 micron
• No interference from scattered radiation
• Low interference from ripples and waves (beam/surface angle up to ±20°)
• Built-in data acquisition and processing
• Waterproof housing for outdoor installation
• Ex-proof option is available
• Mounting at stationary points, buoys, motor boats
• Long-term operation without maintenance

Reference : AH-1

AH-1 analyzer is designed for continuous automatic monitoring of total content of calcium and magnesium salts (total hardness) in water. Analyzer performs automatic monitoring of water stream for technological processes of water treatment, power generation industry, for environmental monitoring. The analyzer consumes virtually no chemicals during measurements. The analyzer may be incorporated in a complex control system of water treatment process.
