It became obvious that there is a need to develop a method to monitor chemical quality in-situ that will identify changes in the chemistry...

Refractive index, a continuous, non-sampling measurement, helps fabs identify slurry composition changes quickly.

Vaporized hydrogen peroxide leaves no residue and is efficient for bio-decontamination in room temperature.

This paper describes the stability of the Vaisala GMP231 in two conditions: heat sterilization cycles and typical incubator atmosphere.

Wind energy developers understand the need to use climate reference data as part of the wind resource assessments.

Though slurry density is a critical parameter for CMP performance, incoming density can vary from batch to batch.

Vaisala is often asked questions about overall weather patterns, especially when investment in wind and solar energy is at stake.

Each stage of development asks different questions about the solar resource and each stage requires varying degrees of information and...

Maximum accuracy is achieved by using the best science and latest technology available in the fields of climate science, meteorology, fluid...

Why remote sensing will become the new standard for wind development financing and operations

Refractive index measurements have established themselves as the technique of choice for qualifying peroxide content in slurries for CMP of...

This document describes the Vaisala BioCover™ material. Test results are given for the estimated disintegration times of the cover, insulation...

The chapters in this document provide information on the importance of radiosonde measurement accuracy, and how accuracy helps to successfully...

Over a decade of lightning research conducted at universities, meteorological services/institutes, and Vaisala have shown that all areas where...

Visibility Measurement for Wind Turbine Obstruction Light Control

In this study we examined water diffusion in stagnant oil in order to predict the increase in moisture sensor response time due to unfavorable...

Breakdown voltage (dielectric strength) is one of the most important parameters of transformer oil.
