Heat Flux Meter Model HFM1

• The HFM1 Heat Flux Meter is a measurement system for analysis of thermal resistance and thermal transmittance of building elements by in-situ measurement. It can be used for measurements according to ISO 9869 and ASTM C1155 / C1046 standards. For ISO 9869 and ASTM C1155 / C1046 standards, the HFM1 is equipped with two Heat Flux Plates (HFP01) as well as two pairs of matched thermistors for differential temperature measurements (four total thermistors).
• Thermistor excitation voltage is measured at every measurement interval for increased accuracy, this voltage reading is used in the thermistor scripts to remove errors introduced from possible voltage fluctuations.

Application :

• meteorology
• building physics
• H-value and R-value determination
• building climate control
