Constant temperature and humidity controller EW-330

タイトルまたは説明

Capable of accurate temperature and humidity monitoring, this product helps prevent condensation and ensure that ambient temperature and humidity meet specific operating requirements. Featuring digital display of set value and measured value, this product allows users to set control values of temperature & humidity manually. Humidifying and dehumidifying modes are optional; heating, dehumidifying and fan cooling can be set easily. Open circuit alarm of heater, cooler and dehumidifier. Open circuit alarm of transducer and auto load cut-off  to prevent long-term overloaded operation resulted from transducer open circuit.
