The temperature & humidity sensor is ideal for hot and humid environments, including sauans. The probe, which is made of stainless steel has a nickel-plated sintered bronze filter. The probe head can cope with pressure drops and high flow speeds, making it suitable for use in ventilation ducts. The sauna temperature and humidity sensor has an integrated 0-10V transmitter, enabling it to be connected to any device with a 0-10V standard signal input.
