Certificates of Calibration Explained

Dwyer Instruments, Inc. offers a variety of calibration services for new or previously purchased products. In 2019, the Dwyer Instruments, Inc. – Engineering Laboratory, located in Michigan City, IN, gained accreditation to ISO/IEC 17025:2017 through the ANSI National Accreditation Board. The Dwyer lab now offers two different types of calibration certificates for our products: a certificate of NIST calibration and an ISO/IEC 17025:2017 accredited certificate of calibration. Now that accredited calibration services are available for select Dwyer products, it is important to know the differences between these two different calibration certificates. Knowing these differences will allow you to understand which calibration certificate will best suit your needs. Continue reading “Certificates of Calibration Explained”

Dirty Jobs | Measuring Livestock Manure Level

Imagine that you’re driving down a country road, and you roll down your window to feel the breeze from the wind. You happen to look to your side as you pass a large barn housing dairy cows. Most of us have seen these farms, but many don’t think about what happens to the manure of the animals or how it is utilized in our everyday lives. Manure slurries and lagoons are a vital function of large scale farms for swine, dairy, and poultry.  Continue reading “Dirty Jobs | Measuring Livestock Manure Level”

Monitoring Air Flow of Hydrogen and Methane Gases

A system integrator in California recently needed to monitor air flow of hydrogen and methane gas, requiring threaded connections to a steel line that the gases flowed through, as well as from the flow sensing device to the transmitter reading flow for their system controller. Hydrogen and methane are difficult gases to deal with, requiring a robust solution to monitor flow through the exhaust line without potentially posing a hazard.  Continue reading “Monitoring Air Flow of Hydrogen and Methane Gases”
