Durable. Dependable. Design you can trust.

ERACHECK PRO is the industry-leading measurement device for CFC-free and reliable oil-in-water or oil-in-soil testing. The only fully ASTM D7678 compliant analyzer on the market, it combines all benefits of the withdrawn IR method ASTM D3921 with the advantages of CFC-free solvents. It measures sub-ppm concentrations of Total Petroleum Hydrocarbons (TPH) and Total Oil and Grease (TOG) in water and soil.

Accurate enough for lab work, while compact and robust for field applications, the ERACHECK utilizes the low-cost solvent cyclohexane, ensuring a safe, simple and environmentally friendly extraction procedure.

ERACHECK’s broad appeal can be attributed to its innovative QCL-IR (Quantum Cascade Laser Infra-Red) technology, which distinctly measures total oil and grease in water. Developed by the QCL specialists at QuantaRed, QCL-IR performs measurement across a wide range (0.5 to 2,000 ppm), a unit precision that exceeds ASTM D7678 standards and outperforms all other infrared techniques.
