Instead, it measures the temperature of the plant leaf and compares this with ambient conditions, giving growers the information needed to improve the accuracy of their controller's VPD calculations.\u003c\/p\u003e\u003cp\u003eWhy leaf temperature matters\u003c\/p\u003e\u003cp\u003eAn environmental controller measures the temperature of the surrounding air, but the temperature of the plant leaf can be different.\u003c\/p\u003e\u003cp\u003eThis difference is important when calculating plant VPD.\u003c\/p\u003e\u003cp\u003eAC Infinity controllers allow growers to enter a Leaf Offset, which accounts for the difference between ambient air temperature and actual leaf temperature.\u003c\/p\u003e\u003cp\u003eFor example, if the plant leaf is cooler than the surrounding air, that difference can be entered into the controller as the Leaf Offset. The controller can then incorporate it into its VPD calculations.\u003c\/p\u003e\u003cp\u003eInfrared leaf temperature measurement\u003c\/p\u003e\u003cp\u003eThe VPD Thermometer uses infrared technology to measure leaf surface temperature without physical contact.\u003c\/p\u003e\u003cp\u003eA 12-point laser guide helps indicate the measurement area, allowing growers to take representative readings from the plant canopy.\u003c\/p\u003e\u003cp\u003eDespatched within 3 working days.\u003c\/p\u003e","brand":"AC Infinity","offers":[{"title":"Default Title","offer_id":60375440359808,"sku":"GAS-ACI-VPD","price":29.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0607\/4643\/2669\/files\/ACI-VPD.webp?v=1794489297","url":"https:\/\/highstreethydro.com\/products\/ac-infinity-vpd-thermometer-gas-aci-vpd","provider":"HIGHSTREETHYDRO","version":"1.0","type":"link"}
