Liquid Technology EPA Protocol (CEMS) calibration gas Methane CH4, selectable concentration from 10ppm to 1%, 33 cubic feet (934 Liters)
Calibration gas is non-returnable

Blending Method:
Although most manufacturers utilize a combination of partial pressure and gravimetric filling. Liquid Technology uses solely gravimetric blending to manufacture all calibration gas standards. This allows us to offer tighter blend tolerances on all gas mixtures including EPA, Primary, Certified and most Disposable Gas Standards.
