From the day rice sprouts, one must measure the rice paddy’s ripening, and when the added amount reaches 1000˚C, hitting the peak, one must harvest the paddy. There is a real danger, however, of harvesting too early or too late. Harvesting at the appropriate time guarantees the best yield and at the same time will yield a great improvement in quality. With this unit, if you set the rice paddy yield just once, it will automatically measure the temperature and display the most fruitful time to harvest.
