U-value, R-value, humidity, and surface temperature measurements made easy

 

The gO Measurement-System is a cloud-based, wireless system for U-value, R-value, surface temperature, and humidity measurements. It allows for simultaneous measurements with up to 16 sensors and real-time remote monitoring. It is the only system on the market which gives you hard data about the insulation quality of building elements. The gOMS is especially designed for applications in building physics.

 Advantages

  • Easy to set-up and use
  • Real-time and remote monitoring via cloud
  • Simultaneous measurments with up to 16 sensor nodes

Why is the U-value important?

Get the Building Physics Newsletter 

  • The U-Value is the most important value for the user independent assessment of a building's thermal performance
  • The heat transfer coefficient (U-value) describes how well a building element is insulated
  • The lower the U-value, the better the insulation
  • Quantitative assessment of heat bridges is possible. Sources of mold can easily be detected

Typical use cases

Asssessing the status quo

A precise status quo assessment of the U-value before a refurbishment increases the quality of the overall planning.

Check before project handover

In case of dispute between project partners, a non-invasive U-value measurement can increase the transparency between the project partners.

Heat bridge and mold detection

Dew point assessment via room humidity and surface temperature measurement. Quantitative assessment of heat bridges via U-value measurement.

Applications in R&D, quality control

Exact measurement tool for U-value measurement in R&D of new insulation materials. Tool for quality control in the production of insulation materials.

Resources: Case studies, white papers, and FAQ

Below you find a list of case studies and white papers about various U-values projects conducted by greenTEG, our customers, and project partners. Please note that the measurements discussed in these resources were made with the gSKIN U-Value Kit, the preceding model of the gO Measurement-System. The measurement principel with the gO Measurement-System remains the same. Contact us if you have any questions.
