Thermometer probe with wet bulb and natural ventilation. ISO7726 standard. The Pt100 element is closed inside a wet cotton sock from a water tank. The water tank has a high reflection factor to avoid water temperature increase due to radiant sources. This sensor is needed for WBGT (ISO77243) heat stress index assessment.
