Gastec Water Vapor Tubes and Methanol Correction Slide Card

Gastec Tube No. 6LP and the Nextteq Methanol Correction Slide Card Perfect Pair for Measuring Water Vapor in Pipelines

TAMPA, FL (January 17, 2012) – Nextteq offers Gastec’s direct-read water vapor detector tube No. 6LP to help evaluate quality assurance for humidity control in natural gas pipelines. The 6LP tube allows for quick and accurate detection of water vapor concentrations with a measuring range of 3-100 lb/MMCF. This tube is perfectly suited to measure the maximum acceptable water vapor concentration of 7 lb/MMCF set by most natural gas distributors, making it easy to maintain gas quality specifications.

The tube's unique construction results in longer stain marks and greater distance between calibration marks, making it easier to read and improving accuracy. With a measuring range of 3-100 lb/MMCF, Gastec’s 6LP provides the broadest range of a direct-read water vapor detector tube on the market. Additionally, it requires only 1 pump stroke and takes only 1.5 minutes for the standard measuring range of 3-40 lb/MMCF.

When processing natural gas, water vapor is commonly removed to improve gas quality. For ongoing quality assurance, water vapor levels are regularly monitored. If methanol is present in the gas, it can interfere with water vapor measurements and require extra analysis and calculations to determine the correct water vapor level. For a precise measurement, Nextteq offers a slide card which provides a simple, on-the-spot correction factor.

The Methanol Correction Slide Card, for use with Gastec Gas Detector Tube No. 6LP (water vapor) and No. 111L (methanol), easily expedites the analysis and reduces the risk of miscalculations. Please contact Nextteq Customer Service at 877-312-2333 x20 or to have a Methanol Correction Slide Card sent to you.

In addition to water vapor and methanol, Gastec offers pre-calibrated, direct-read detector tubes for over 600 applications including hydrocarbons and hydrogen sulfide. To maintain the highest level of quality, Gastec products are manufactured in ISO-9001 certified manufacturing facilities. Additionally, Gastec Detector Tubes and Gas Sampling Pumps are designed, manufactured, and calibrated to work together to produce accurate readings.

Gastec Detector Tubes and Gas Sampling Pumps are manufactured by Gastec Corporation. Nextteq LLC is Gastec’s exclusive master wholesale distributor.
