Thermal Monitoring Kit For Buildings
The QRU-100 Thermal Monitoring Kit for Buildings is designed for building inspectors, energy audit specialists, researchers, and energy advisors. It is easy to use, lightweight and comes pre-configured and ready to go.
QRU-100
The QRU-100 is designed to make the thermal performance evaluation of buildings and components easy, efficient, and accurate.
A critical requirement for modern construction, renovation, quality assurance, and energy efficiency assessment, the QRU-100 thermal monitoring kit includes separate indoor and outdoor measuring units. Indoor heat flux monitoring, together with indoor and outdoor temperature sensors, allow the QRU-100 to measure both thermal transmittance and thermal resistance, the U and R-Value of a wall or similar structure based on the standard methods defined in ISO 9869, ASTM C1046 and ASTM C1155.
The QRU-100 is delivered in a weather-proof case. Each measuring unit has a long-life battery and ultra-high-resolution data-logger that can store up to 4 million data points, preconfigured and ready to use.
Key Features:
- Pre-configured, quick set up & ready to go
- Tough carry case & Weather resistant housing
- Independent ultrahigh resolution data loggers in each unit
- Compatible with ISO 9869, ASTM C1046 & C1155 in-situ thermal measurement
