Detector tubes are an economical way to reliably determine gas concentrations on the spot in the natural gas industry. The primary gases measured using detector tubes are:
- water vapor
- hydrogen sulfide
- carbon dioxide
The Uniphos system consists of a manually operated hand pump and the detector tube for the specific gas. The detector tube system is often used with a gas sampling bulb connected directly to the gas supply.
The detector tubes are calibrated by the manufacturers and delivered with an expiration date stamped on the packets. The pumps are hand operated aspirating type pumps which should be leak tested prior to use. Leak testing the ASP-40 piston style pump takes only three minutes.
