ST-1520 Infrared Oil Analyzer
Product Introduction:
The ST-1520 Infrared Oil Analyzer complies with standards HJ637-2018, HJ1077-2019, SY/T0530-2011, GB/T 12152-2007, GB/T4284-2018, and GB/T18483-2001. It is suitable for detecting the concentration of total oil, petroleum, and animal/vegetable oils in samples such as industrial wastewater, domestic sewage, cooking fumes, irrigation water, and solids (oil sludge). It features high automation, reliable performance, excellent repeatability, and simple operation. The ST-1520 Infrared Oil Analyzer is widely used in environmental protection, power, petroleum, chemical, pharmaceutical, food, education, and other industries.
Compliant Standards:
lHJ 637-2018 Water Quality - Determination of Petroleum and Animal/Vegetable Oils by Infrared Spectrophotometry
lHJ 1077-2019 Stationary Source Emission - Determination of Cooking Fume and Oil Mist
lGB/T18483-2001 Standard Method for Monitoring Cooking Fume in Catering Industry
lGB/T4284-2018 Monitoring Method for Control Standards of Pollutants in Agricultural Sludge
lSY/T0530-2011 Method for Determination of Oil Content in Oilfield Produced Water
lGB/T12152-2007 Determination of Oil Content in Boiler Feed Water and Cooling Water by Infrared Spectrophotometry
Features:
l Baseline Stability: No baseline drift, real-time automatic zero tracking (automatically eliminates baseline drift). The system collects signals both when the light source is on and off, achieving real-time automatic zero tracking, simplifying operation, and improving long-term signal stability.
l Software System: Dual-system analysis suitable for using tetrachloroethylene as the extraction solvent.
l Calibration Methods: Built-in correction factors, single-point calibration for instrument constants, and standard curve calibration for user selection. Automatic system calibration without manual positioning. Includes standard oil samples above 40mg/L; the software workstation automatically calibrates at 2930cm?1, 2960cm?1, and 3030cm?1 bands.
l Optical System: Modular optical and hardware systems with long lifespan and maintenance-free operation. Light source guaranteed for 10,000 hours. Uses electrically modulated light source technology to ensure signal stability.
