Naturally ventilated humid temperature sensor
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.
• Wet temperature measurement with natural ventilation as required for the calculation of the WBGT index (ISO7243) in fixed and/or outdoor installation;
• Disegnaed as described in the ISO7726 standard for the “wet bulb temperature”;
• 1/2 litre water tank for more than 30 days water autonomy;
• Well protected by the solar radiation;
• In-house ISO17025 calibration laboratory;
• Accessories for 4-20mA and RS485 output.
