ERACHECK X isa high-end dual-beam non-dispersive IR spectrometer for the highly accurate measurement of oil-in-water. Based on the inexpensive and environmentally friendly CFC-free solvent, cyclohexane,ERACHECK Xmeasures TOG, TPH, and FOG in water in full compliance with ASTM D8193 with sub-ppm precision, offering excellent correlation to EPA 1664, ISO 9377, and OSPAR.

The oil-in-water analyzerERACHECK Xiseralytics latest product innovation. It is the first analyzer based on our new portable and easy-to-operate instrument platform, convincing with a rugged aluminum housing with most compact dimensions, still offering a large color touchscreen and a state-of-the-art built-in industry PC.
