The IONICON Liquid Calibration Unit (LCU) evaporates aqueous standards into a gas stream, resulting in a gas flow containing compounds at defined trace concentrations. This gas can be used for precise calibration of trace gas analyzers over an extensive range of compounds and concentrations.
Modular calibration system primarily designed as transfer standard to synchronize analyzers in different measuring stations. Transport of the span gas cylinders normally used as transfer standard is unnecessary when using a permeation oven.
The calibration system serves the mandatory zero and end point verification of gas analyzers, especially those in automated measuring networks. The zero and end points are verified with a signal from the measuring network computer; the calibration can also be activated with the keyboard at the front of the CMK.
For measurement of gases that do not require hot measurements, Protea can supply sample probes of various material construction. This includes probes made of materials such as PEEK allowing for measurement of possible corrosive gases.
