The regulation language in U.S. Pharmacopeia Standard 797 (USP 797) has long been the guiding principle for cleanliness in hospital pharmacies that treat cancer patients with compounding sterile preparations (CSPs). For airflow in these special rooms, USP 797 outlines how spaces are to be pressurized, and what are permissible parts per million (PPM) particle counts.

How do we know that hospitals are safe?
Hospitals and outpatient facilities serve a critical need in global communities. They provide emergency care for the sick, but we also rely on them as a safe zone for treating communicable diseases and keeping the public at-large safe. But how can we know for certain that a hospital is clean and safe, and that we won’t get sick from something another ill patient has carried in?
User-side energy submetering is becoming increasingly popular in new commercial construction and renovation projects alike. The latest advanced LEED certification requires operator-owned submeters to be installed in high consumption areas and facilitate continuous tracking of total consumption for an entire structure.

How to Select a Power Meter
What Are You Monitoring?
One critical consideration when searching for a proper power meter is to determine what you're measuring. Is the monitored load signal-phase, split-phase or three-phase? What voltage/current ranges are going to be monitored?
If you're interested in a power meter for residential or light commercial applications, then typically a single or split-phase meter would be the best cho

What is a Vivarium?
To most people, the term “vivarium” conjures up the image of a small fish tank-like glass box where a pet rat or gecko lives. While this is not incorrect, vivariums in biomedical research facilities are a bit more robust than what you might see in a high school science lab.

Vivarium Defined
Vivariums are enclosed areas designed to provide a stable environment for animals and plants for observation or scientific research. Often, vivariums contain a portion of an ecosystem for a particular species with controlled environmental conditions on a smaller scale. A vivarium you would find in an academic research setting contains multiple racks of various sizes depending on the species it contains.

What is Total Harmonic Distortion?
Imagine a tone being played by two musical instruments - let’s say middle C (261.63 Hz). While the pitch played on a piano may be the same as on an electric guitar, its timbre is very different. The sound wave generated from a piano or a simple synthesizer is relatively simple and clean, but the sound wave coming from an electric guitar is often very distorted for effect and contains natural harmonic overtones.
Understanding specific job requirements, such as performance, installation, amperage load and environmental factors is critical to selecting the proper current transformer for an application. Conventional current transformers (CTs) come with their limitations as they are difficult to install and are lacking in performance and measurement range. Rogowski coils have significant advantages with regards to installation, cost and performance.
