DynacalPenetrating pipeIt is a small, inert container containing pure chemical substances in equilibrium between two phases. It can be gas/Liquid phase, can also be gas phase/Solid phase. At a constant temperature, the substance inside permeates outward through the permeation site at a certain rate. Insert into the carrier airflow to generate the required concentration for the experiment. Used for calibrating gas analyzer systems, hazardous gas alarm testing, long-term research on materials and biological systems, and any application that requires stable trace concentrations.

The purpose of a gas calibrator is to establish a standard point for analysis. The penetration rate can be traced backNISTThe method is to determine the decrease in weight over a known period of time at a known temperature.
