It has a wide range of applications including but not limited to use in schools, factories, warehouses, offices or home for decor and scene design, growing plants for ensure appropriate light levels etc. Features Ranges: 0.1 to 400,000 Lux; 1-40,000 FC Accuracy: 4%rdg 0.5%f.s (less than 10,000 Lux;1,000 FC) / 5%rdg 10dgt (more than 10,000 Lux;1,000FC) Repeatability: 2% Temperature characteristic: 1%C Photodetector type: silicon photodiode with filter Operating temperature: 32-104 degrees F (0-40 degrees C) Sampling Rate: 2-3 times per second Indoor vegetable plants and other growth requirements for light are very high, different light intensity will cause different growth effects. Using the 881D to measure and control light intensity is a good choice. Similar to some public places in hospitals, there are different light intensity standards. How to avoid awkward situations, use 881D to test it quickly When taking pictures, lighting is the most important thing. The quality of a photograph is determined by the light. Use 881D to scan the lighting standard, which makes your photography more convenient. Note: Due to the light and screen setting difference, the color of the product may be slightly different from the picture. As the manual measurement is different, please allow a slight size difference. Shipping Quantity: 1 pcs
