What are Room Pressure and Room Status Monitors?

Jonathon Jachura — Wed, 07 Apr 2021 16:18:38 +0000

Differential pressure between two rooms prevents dust, particulates, and pathogens from entering or exiting one room and going into the other. Depending on the relationship between rooms, one room will be under positive pressure when referenced against the other. This positive-negative pressure relationship between two spaces is the main idea behind clean rooms and isolation …

Importance of Sensor Stability in Educational Facilities

Jonathon Jachura — Wed, 17 Mar 2021 17:23:46 +0000

Educational facilities, or public and private institutions devoted to teaching students, differ in physical size and level of education programs. These institutions can range from preschool to university levels, all of which need proper heating, ventilation, and air conditioning (HVAC) systems and indoor air quality. While indoor air quality (IAQ) is important for everyone’s health, …

Importance of Sensor Stability in Healthcare Isolation Rooms

Jonathon Jachura — Wed, 10 Mar 2021 17:47:10 +0000

The purpose of a healthcare isolation room is to prevent patients with contagious illnesses from spreading to others or to keep immunocompromised patients safe from exposure to airborne pathogens. As such, there exist two types of isolation rooms, either positively or negatively pressurized. Positive pressure isolation rooms are designed to keep pathogens and outside air …

How is Stability Related to ASHRAE 62.1 Standards?

Jonathon Jachura — Wed, 27 Jan 2021 15:46:06 +0000

ASHRAE 62.1 Standard for Ventilation for Acceptable Indoor Air Quality provides recommendations for minimum ventilation rates and other parameters to ensure good indoor air quality (IAQ). Keeping the IAQ at a safe level will help to minimize any adverse health effects caused by air quality factors. The 62.1 standard is intended for both new building …

What is Stability and Why is it Important?

Jonathon Jachura — Wed, 13 Jan 2021 15:54:26 +0000

Stability is defined as a change (or lack of change) in accuracy over a period of time. Drift is commonly used as a specification to illustrate the stability, or change in accuracy over a period of time, commonly shown as X%/year where X = a number; i.e. 0.25%/year. In this scenario, a device with a …
