HEATEST is one of the few laboratories in the field of heat output measurement that is included in the List of Calibrated NBs, which allows us to guarantee the highest possible measurement accuracy. We regularly keep the status of a calibrated laboratory by successfully participating in the round robin test (RRT) organized by SG03-WG1 and by regularly measuring repeatability and reproducibility in relation to the reference laboratory.

Accredited testing laboratory L1477

Do you need to measure Heat or Cooling output or other characteristics of your products?

Since 2007, we perform testing radiators, convectors, chilled beams, air elements and a small fan according to European standards.
