With over 4,000 oil and grease monitors in world-wide use today, InfraCal 2 Analyzers, originally developed by Wilks, have become a standard for the petrochemical industry.  These essential tools ensure that oil content levels are below the regulated limit in water, drill cuttings, and soil.  Both the InfraCal 2 TRANS-SP and InfraCal 2 ATR-SP are recommended for measuring oil in water, TPH in soil or FOG in wastewater.

Try our new Product Selector to choose the InfraCal 2 analyzer best suited for your application requirements.  Deciding criteria include your sample matrix, the solvent you prefer to use for the extraction procedure and the level of detection required.

The InfraCal 2 Analyzers for measuring oil in water or soil can be used for a number of different applications.
Our primary applications are listed below:

Oil Level in Produced Water
FOG in Wastewater
TPH in Soil Remediation
Oil Content in Frac Water
Hydrocarbons in Drill Cuttings

    The fact that InfraCal Analyzers over 10 years old are still operating in the corrosive environment of offshore oil rigs attests to their rugged, dependability. The analysis procedure takes less than 15 minutes and can be done by minimally trained personnel. They use field proven infrared technology for measuring oil in water, oil content in drilling mud or drill cuttings, TPH (total petroleum hydrocarbons) in soil and FOG (fats, oil and grease) in wastewater.

    The InfraCal 2, the latest introduction to our easy to use analyzers, uses the same measurement technology as our InfraCal TOG/TPH Analyzers with added features such as data storage and transfer, multiple calibrations and password protection for instrument settings. The InfraCal Analyzers are stand-alone fixed filter infrared instruments that give results that are comparable to EPA 1664 and ISO 9377-2 and comply with ASTM D7066, EPA 413.2 and 418.1.
