gOMS II – Wireless U-Value / R-Value Measurement System

2049,00 CHF

greenTEG’s second generation system for Wireless U-Value and R-Value assessment, scalable to 5 measurement points per system.

This wireless measurement system is perfect for energy expenditure, building envelope energy efficiency or building insulation assessment. This all-in-one device is suited for a broad range of building energy consumption setups.

Determine wirelessly and simultaneously:

  • The U-value of various building elements: Double glazing, windows, walls, roof, floor, façade.
  • The U-value of multiple construction materials: glass, brick, wood, Phase Change Materials (PCM), concrete and cavity wall!

Evaluate your energy expenditure from simple insulation building measurement to industrial or environmental climate chambers.
