Sonda CO₂ GMP251

Danish researchers have demonstrated that it is possible to remove most of the carbon dioxide (CO2) from the emissions of a waste incinerator, and by demonstrating the viability of the process, the researchers believe that they have developed a key technology in the fight against climate change.

Diferentemente do que ocorria no passado, quando as sondas de medição não podiam ser usadas de forma autônoma, a nova onda de sondas de medição inteligentes pode operar de maneira independente, sem transmissores adicionais. 

Cool Dynamics Qld has been delivering commercial and industrial refrigeration solutions to the fruit and vegetable supply industry across Australia’s eastern seaboard for more than two decades. Director Bruce Townsend tells us why Vaisala’s measurement sensors are his number-one choice for maintaining optimal conditions in the controlled storage atmospheres that his customers rely on.

Whatever the end product, process, or need, the goals are similar in almost all applications: a CO2 measurement that accurately reflects the environment and meets the application requirements.

Boston IVF provides Assisted Reproductive Technology inlcudng IVF in 28 locations. Boston IVF’s embryo incubators are one of the most important pieces of equipment at their facilities.

Roal Ltd is one of the world´s largest enzyme companies producing enzymes for different industrial applications, for example, for baking, food, technical and feed industries. The company is jointly owned by Associated British Foods and Altia Corporation, a publicly held beverage company that focuses on wines and spirits and operates in the Nordic and Baltic countries. The biological process used to produce the enzymes is called fermentation and Roal produces enzymes in submerged fermentation units. 

The CARBOCAP® story began in 1992, when micromechanical sensors were being intensively researched at Vaisala. The groundbreaking idea of miniaturizing the Fabry-Perot Interferometer (FPI) was born, leading to collaborative development work with VTT.

Controlled  atmosphere  (CA)  storage  is a  widely  used  technique  for  long-term storage of freshly picked fruits and vegetables. Historically, CA storage has been the  primary  method  for  the  long-term storage  of  apples.  Through  a  biological process  called  respiration,  apples  take in  oxygen  and  generate  carbon  dioxide, water, and heat.

Discovered in 1940, the painted cavern of Lascaux in the Southwestern France’s Dordogne region is the most famous ornamental prehistoric cave of the world. The cave consists of a large amount of images of animals such as bisons, aurochs, deers, horses, lions, and rhinos as well as monumental hunting scenes and different objects and signs.

By introducing a ventilation system based on the measurement of carbon dioxide, a Finnish turkey farmer was not only able to improve the living environment for his indoor reared turkeys but also made savings in his energy bills. The system is based on the Vaisala CARBOCAP® Carbon Dioxide Transmitter GMT222 ( *GMT222 is replaced by the GMP252 ).
