STC-3028 \u2013 Complete Temperature & Humidity Controller for Incubators & Hatcheries<\/h2>\n

The STC-3028 Digital Temperature and Humidity Controller<\/strong> is an all-in-one solution for automatic control of both temperature and humidity. With dual relays (10A each) and an AM2320 digital sensor, this controller can independently manage heating\/cooling and humidifying\/dehumidifying simultaneously. Perfect for egg incubators, hatcheries, aquariums, mushroom farming, tobacco factories, and pharmaceutical storage. Operating voltage: AC 100-240V.<\/p>\n
