日本久保田铁工公司研制出 XA-750型水果成熟度测定仪,并投放市场。该仪器具有体积小、质量轻、便于携带、不损伤果实和测定迅速等优点,适用果农测定甜瓜的成熟度和品质。仪器的工作原理是:用灵敏度高的气体传感器,检测甜瓜在生长过程中放出的气体量,将测量值与事先贮存在微型计算机内的标准值相比较,据此判断果实的成熟度。 Japan Kubota Iron Works developed XA-750-type fruit maturity tester, and put on the market. The instrument has the advantages of small size, light weight, easy to carry, does not damage the fruit and determination of rapid, suitable for measuring the maturity and quality of melons. The working principle of the instrument is to use gas sensors with high sensitivity to detect the amount of gas released by the melon in the growth process and compare the measured value with the standard value stored in the microcomputer in advance to determine the maturity of the fruit.
