Description Applications: Suitable for places requiring heating/cooling, humidification/dehumidification, such as grain silos, warehouses, computer rooms, farms, incubators, and textile industries. Outdoor junction boxes and distribution boxes (automatic heating and dehumidification) prevent leakage caused by misoperation. Indoor automatic heating and dehumidification high-voltage power distribution units and high-voltage switch mechanism boxes automatically heat in low-temperature environments to prevent switches from stopping due to low temperatures. Features: Displays temperature and humidity; can use different models to control temperature and humidity changes; has RS485 functionality. High-performance, high-precision, durable temperature sensor capable of long-term operation in various environments.
