Cleanrooms are some of the most demanding environments for HVAC systems. Strict environmental conditions must be rigorously maintained to ensure product quality, process reliability, and regulatory compliance. Despite this, many cleanrooms still rely on static HVAC strategies that don’t adjust to re…

“You’ve got to start with the customer experience and work backwards to the technology.”  

With these words, cofounder of Apple Inc. Steve Jobs laid out a dream and a challenge to design engineers everywhere. But in a world of accelerating change, it often seems like expert operators are required more…

Production in cleanrooms and dry rooms requires accurate sensors to guarantee product quality and ensure regulatory compliance. That means regular calibration is a must. Loop calibration is a way to ensure the integrity and traceability of an entire environmental monitoring system without taking sen…

Pressure differentials inside cleanrooms are not very large, as Vaisala’s Senior Project Engineer Sean Murphy explains, most are set somewhere between 5-15 Pascal. However, maintaining that differential is a critical part of the overall cleanroom contamination control strategy. These small pressure…

Humidity sounds simple in theory – after all, it’s just a measure of water vapor in air. But not everyone understands the relationships between different humidity parameters, or how humidity changes with temperature and pressure. This article aims to demystify key humidity parameters and explain why…

Roughly 80% of the world’s data centers still rely on air cooling. Fixing a ‘half-degree’ error there can avoid around $805 million in cooling waste every year, about $8 billion over a decade, based on moderate 10 MW sites.

Vaisala, a global leader in measurement instruments and intelligence for clim…

Critical life science applications like growing cells in incubators, sterilizing process equipment, and storing life-saving medicines in temperature-controlled warehouses rely on accurate, stable measurements. Handheld instruments provide technicians with a quick and convenient way to spot check, ca…

The Vaisala Polaris family of process refractometers has a wide range of uses in processes where liquid concentration measurements are required. You can use a Vaisala Polaris instrument alongside the Vaisala Indigo80 Handheld Indicator to get a range of additional benefits in industrial processes. T…

Vaisala, a global leader in weather, environmental, and industrial measurements, has launched its latest data logger designed for fast and reliable communication to the viewLinc Continuous Monitoring System. The new VDL200 data loggers monitor Relative Humidity, Temperature and Carbon Dioxide in con…

Many industry players rely on precise measurement of indoor climate in their production facilities and other establishments. However, until now, only large companies had the resources to establish measurement infrastructures that enable functions such as remote monitoring or simple scalability. Vais…
