In association with a pyrolyzer and the Gastec pump, the Pyrotec tubes accurately measure the gas concentrations of many substances: refrigerant gases (R11, R12, R22, R112, R113, R114, R123, R124, R141B, R225); halogenated hydrocarbons (Acetonitrile, Halothane, Methyl chloride; Methylene chloride, Methyl sulfide), nitro kerosenes, and anesthetics gases.
Gastec Pyrotec tubes for spot measurement of refrigerant gases, halogenated hydrocarbons, and some anesthetic gases
In combination with the battery-operated Pyrotec 840 Pyrolyzer and the Gastec GV-100 and GV-110S manual sampling pumps
Simple, economical, and accurate measurement in a few minutes
Filament lifetime: approx. 1000 measurements of 20 ppm
Simple, fast, and economical measurement method
The gas sample enters the Pyrotec 840 pyrolyzer via the Gastec suction pump and decomposes itself (or "cracked") thermally into a substance reacting chemically with the reagent in the Pyrotec tube (colorimetric reagent tube). This is a simple and economical method of measuring certain freons and anesthetic gases.
