Permeation tubes and devices from VICI Metronics provide a more convenient, reliable—and cost-effective—gas calibration standard solution.
- Dynacal® Permeation Tubes – Many laboratory users choose Dynacal devices for compact, high-accuracy, gas calibration within a temperature-controlled environment.
- Wafer Devices – Wafer devices have only a small window containing a permeable membrane, called a wafer, providing the lowest available emission rate, greater rate control, and enabling containment of gases with high-vapor pressure.
- G-Cal Permeation Devices – designed for use in the field, G-Cal devices are less temperature-sensitive, operating at room temperature, and offer the highest available emission rates.
