Manufacturing Excellence Since 1931
The current COVID-19 pandemic spread and breadth is unprecedented. Because of this, it is important that precautions are taken when reopening schools and office buildings. The question we find ourselves asking as professionals in the HVAC trade is this:
How do you return the HVAC system back to normal operations (and continued operations) during this pandemic? Continue reading “Ensuring HVAC System Safety for Reopening Schools & Office Buildings”
Room pressure monitors are devices that monitor differential pressure between two rooms or areas. Differential pressure is the difference of two pressures being sensed.
There are several applications where it is important to maintain a pressure difference between two rooms. This helps to ensure that there are no contaminants entering or exiting a protected area. In a medical setting, an isolation room requires a pressure differential to make sure that no bacteria, pathogens, or viruses enter (or leave) the isolation room. This protects healthcare professionals, patients, and other guests, and minimizes the spread of germs. Room pressure monitors would also be used in areas such as: pharmaceutical manufacturing, semiconductor manufacturing, clean rooms, research labs, vivariums, and clean manufacturing areas.

Several applications require manual reset switches, which are switches that need to be physically reset by an individual for a process to continue or restart. A manual reset is often needed when an area has to be inspected prior to equipment restart. This can help to ensure the safety/inspection of both equipment and other individuals in the area.
Some switches have a mechanical manual reset (such as the Dwyer Series 1900, 1831, and 1800). However, there may be a need to have a manual reset for applications beyond what these switches are designed for. If a pump is allowed to run with a clogged filter, for example, this may severely damage the pump. Continue reading “How to Program a Switch for Manual Reset”
World Accreditation Day
Yesterday (June 9, 2020) marked this year’s World Accreditation Day, which is a global initiative established by the International Laboratory Accreditation Cooperation (ILAC) and the International Accreditation Forum (IAF) to promote the value of accreditation.
This year’s focus was on how accreditation improves food safety, supporting the confidence of consumers, suppliers, purchasers, regulators and specifiers in the quality and safety of food [1]. When it comes to ensuring food safety, consumers and suppliers rely on their equipment and calibration providers to comply with the appropriate international standards, such as ISO/IEC 17025:2017.
Attaining accreditation status to ISO/IEC 17025:2017 is a rigorous process that ensures that the technical competence of personnel, the ethics of personnel, and the reliability of the organization itself are at a level that can be recognized on an international scale. The Dwyer Instruments, Inc. Engineering Laboratory is proud to be able to provide ISO/IEC 17025:2017, ANSI/NCSL Z540-1-1994 and ANSI/NCSL Z540.3 Section 5.3 accredited calibrations on pressure products that are used in these critical food safety environments.

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”
