ASTM D7678

ERACHECK PRO's patented measurement principle is built around a high tech quantum cascade laser spectrometer, which outperforms other infrared techniques by several orders of magnitude in terms of optical power. This cutting-edge technology works without a single moving part, making it highly robust. ERACHECK PRO is the only analyzer capable of measuring oil-in-water down to 0.2 mg/L using CFC-free solvents in full compliance with ASTM D7678.
