About Kahn Hygrometers

To measure the moisture content of gases passing through its adsorptive systems, Kahn developed an electrolytic hygrometer in the early 1960’s. Incorporating the latest technologies, this product line has been continuously expanded and today includes a wide range of moisture measurement instrumentation equipped with ceramic, aluminum oxide and chilled mirror optical moisture sensors.

A common application for the Kahn portable hygrometer is remote monitoring of the water vapor content of natural gas pipelines.

For the U.S. Navy, Kahn has provided portable hygrometers to measure the moisture content of dry nitrogen which serves as an insulating gas surrounding the optics on submarine periscopes.

US National Centers for Environmental Information (NCEI).

Finding Data by Category

Online — The demand for high-value environmental data and information has dramatically increased in recent years. To improve their ability to meet that demand, the USA’s former three NOAA data centers

  1. The National Climatic Data Center,
  2. The National Geophysical Data Center, and
  3. The National Oceanographic Data Center, which includes the National Coastal Data Development Center,

have merged into the National Centers for Environmental Information (NCEI – www.ncei.noaa.gov/).

NCEI is responsible for hosting and providing access to one of the most significant archives on Earth, with comprehensive oceanic, atmospheric, and geophysical data.

From the depths of the ocean to the surface of the sun and from million-year-old sediment records to near real-time satellite images, NCEI is the Nation’s leading authority for environmental information.

NCEI continues the tradition of excellence, unmatched expertise, and trusted, authoritative data that the previous three Data Centers established. The top priority during the near future is to build on the full spectrum of atmospheric, oceanographic, coastal, and geophysical products and services that the Data Centers delivered.

While NCEI’s product portfolio will evolve as current products and services are assessed, no products or services are currently slated to be cut or reduced. By using consistent data stewardship tools and practices across all of our science disciplines and by forging an improved data management paradigm, we expect to provide users with improved access to environmental data and information archive products.

For more information, please visit www.ncei.noaa.gov.

Will their websites’ URLs change?

Existing links and domain names (e.g., www.ncdc.noaa.gov) for the Data Centers will continue to be accessible. Over time, the merged Data Centers will develop a plan to consolidate domains.

This change will be advertised, and all appropriate redirects will be established.

The NCEI landing webpage has been established as an overview to the new organization.

How will this impact users?

The goal is to provide minimal impacts to users in the short-term. Existing products and services will remain on their current sites, and access will not change. In the long-term, the merger will improve the creation of new products and the access and delivery of existing products and services to users.

A Trusted Authority on Weather and Climate Information

The Nation needs a trusted authority on weather and climate information. Every day, governments, businesses, and individuals make long-term decisions—affecting lives and livelihoods—that require an accurate understanding of the natural environment. NCEI is well positioned to respond to this need by building upon the former National Climatic Data Center’s 61 years of data and customer-focused science, service, and stewardship.

NCEI develops national and global datasets, which are utilized to maximize the use of our climatic and natural resources while also minimizing the risks caused by climate variability and weather extremes. NCEI helps describe the climate of the United States and it acts as the “Nation’s Scorekeeper” regarding the trends and anomalies of weather and climate.

NCEI’s climate data have been used in a variety of applications including agriculture, air quality, construction, education, energy, engineering, forestry, health, insurance, landscape design, livestock management, manufacturing, national security, recreation and tourism, retailing, transportation, and water resources management.

About NOAA

NOAA, The National Oceanic and Atmospheric Administration, provides daily weather forecasts, severe storm warnings, and climate monitoring to fisheries management, coastal restoration and supporting marine commerce, NOAA’s products and services supporting economic vitality. These affect more than one-third of America’s gross domestic product. NOAA’s dedicated scientists use cutting-edge research and high-tech instrumentation to provide citizens, planners, emergency managers and other decision makers with reliable information they need when they need it.

Rotronic’s Humidity Academy

CRP5 - Clean Room Panel
ROTRONIC New CRP5 – Clean Room Panel

Online  —  The Humidity Academy that was setup by ROTRONIC USA is the way that ROTRONIC have chosen to share their knowledge.

Starting with the first topic relating to the theory of relative humidity. They will work chapter through chapter bringing light into the dark or in their language humidity to the drought.

The first two chapters are online now and it will be interesting to update this article as the later chapters are added.

Chapters

  1. What is Humidity?
  2. Relative Humidity, Pressure and Temperature
  3. The Capacitive Sensor
  4. The Wet Bulb/Dry Bulb Technology
  5. Summary of Other Technologies
  6. Choosing the Right Humidity Measurement Technology

What Is Humidity?

Humidity is defined as some measure of the water vapor content of air (or other gas). The term “humidity” is a general term to quantify the amount of water vapor in the gas.

The term “humidity” is often interchangeable with “relative humidity”, but there’s a significant difference between these two terms in the context of precise measurement.

This chapter explains why the difference between these two terms matters for people who are in the business of measuring water vapor in sensitive environments, and it covers the terms and definitions used to quantify the amount of water vapor in the gas…
