bob体育竞技Apogee仪器’ leaf and bud temperature sensor (formerly called the radiation frost detector) is an innovative temperature sensor designed to mimic leaves and flower/fruit buds, which can sometimes drop well below the ambient air temperature due to long-wave radiation loss on clear, calm nights. Knowing exactly when a radiation frost even is occurring allows you to activate frost protection equipment in time to protect your crops and eliminates starting frost protection too early, which wastes money.
