This innovative thermal camera measures surface temperatures, relative humidity, ambient temperature, and dew point temperature. It effectively visualizes temperature gradients, thermal bridges, and condensation moisture. The visual dew point function combines the features of a thermal camera, digital camera, and hygrometer. This produces informative thermal images with specific markings of surfaces that have reached or fallen below the dew point temperature, making it ideal for critical indoor inspections. Its diverse applications include building inspections, work on electrical systems, machinery, heating and ventilation systems, as well as locating heat sources or cold areas.
