Permeation devices provide a stable concentration of a specific trace chemical, including those with low vapor pressures. Calibration gas generators, used with their respective permeation devices, generate known concentrations of various gases and liquid vapors.

Metronics also manufactures toxic gas and oxygen monitors – small, portable units that are ideal for field use, as well as contaminant traps and gas specific purifiers.

Calibration gas generators

Gas generators use permeation devices to generate known concentrations of various gases and liquid vapors. They offer the easiest method of calibrating toxic gas detection equipment, gas analyzers, and chromatographs.

Applications include air pollution monitoring, industrial hygiene surveys, odor surveys, and analyses in chemical, petrochemical, paper, power, and related industries.

Dynacalibrators®
Using Dynacal permation devices as the trace gas source, Dynacalibrators deliver precise concentrations from ppb to high ppm for hundreds of different compounds. Portable and lab bench models.
G-Calibrators
In these rugged portable units with G-cal permeation devices, since the permeation rate remains fairly stable over changing temperatures, temperature controlled ovens aren’t required for most applications. G-Calibrators operate in ambient temperatures from 15°C to 45°C.

Toxic gas and oxygen monitors

Low-cost, battery powered units are ideally suited as a personal monitor for field use, but have a sensor cable option for remote sampling.

Gas purifiers and contaminant traps

Gas purity is essential in any application requiring extreme sensitivity. Contaminant traps and gas purifiers for specific gases dramatically reduce the levels of contaminants, enhance the purity of lower grade helium, and help insure instrument stability, reproducibility, and lower maintenance costs.
