Dust, gases, and particles of every size are byproducts of natural forces and human activity. Forest fires, volcanoes, and other natural disasters add particles to the air we breathe, as do modern industry, energy generation, and transportation. To manage the impact on our communities, the world shares responsibility for measuring and assessing environmental risks.

We offer tools and services to help keep humidity, dew point, carbon dioxide, and temperature instruments calibrated and functioning properly. Hand-held instruments for all of these parameters are useful for calibrating field instruments and for use as check standards.


Integrated Weather Measurement Solution Increases Building Efficiency

Outside temperature, wind conditions and solar radiation all impact the distribution of heat within buildings. Building automation systems regulate temperature, humidity and air quality. To increase building efficiency through precise weather measurement we recommend you to integrate a multi-parameter weather transmitter (WXT530) into your automation solution.


Construction Site Dust Monitoring

Construction projects tend to create large amounts of dust and other fugitive emissions that can be harmful to human health and the environment.

Dust from various construction processes contain a wide range of particle sizes and material types. The larger particles, usually termed ‘dust’, tend to settle out of the air quickly and are mostly a health hazard to the operators in the immediate area. The smaller particles, known as PM10, are usually invisible and may not seem to be an obvious hazard. However, they can be carried much further in the air potentially causing health hazards both to workers on the site and to people living and working outside the site boundary in the local neighborhood.

Implementing the proper aerosol monitoring instruments can confirm that dust suppression controls are working properly - and more importantly - provide the needed data enabling you to protect your employee and the surrounding communities.


Monitoring greenhouse environments

Greenhouses are closed environments in which the conditions for plant growth are optimized. Optimal controls require information from both the indoor and outdoor environment. Typically, carbon dioxide (CO2), relative humidity and temperature are measured in...




The international collaboration leads Vaisala and the Finnish Meteorological Institute (FMI) to Mars on board of NASA's Mars Perseverance Rover. Vaisala's sensor technology combined with FMI's measuring instruments is used to obtain accurate and reliable pressure and humidity data from the surface of the red...




Understanding the carbon dioxide flux in forest ecosystems has become an important subject in the international effort to prevent global warming. Observations of the carbon dioxide flux between the atmosphere and forests are promoted worldwide. The components of the carbon budget in a forest ecosystem - the carbon dioxide flux released from the forest floor and that released from or absorbed into foliage - are often...
