FAQs

1. How are our portable leaf area meters better as compared to other stationary models?

portable leaf area meters are battery operated, allowing on-site analysis omitting the need for an external power source. It requires minimal set up time, is cost-effective and easier to maintain and repair as compared to other stationary models which are expensive, requires a power source for their operation, difficult to set up, maintain and repair.

2. Can Leaf Area Meter be used in case of varied leaf geometry?

product has the capability to measure the leaf area irrespective of their different shapes and sizes. Furthermore, it is able to produce accurate area measurements of irregularly shaped and perforated leaves.

3. What is the maximum area that can be detected by the sensors of our leaf meter?

The maximum area that can be detected by the optical sensors of our leaf meter is 16,000 cm2. Hence, you can easily measure leaf area of plants with huge leaves such as Banana, Colocasia and Giant Water lily!

4. What is Leaf Area Meter?

Leaf Area Meter is used to precisely measure the surface area of leaves. It makes use of latest optical scanning and imaging technology to achieve fast yet reliable results.

5. What is the working principle of Leaf Area Meter?

leaf area meter works by optical scanning of the leaf placed on its transparent surface. Light emitting diodes (LEDs) present below this surface illuminates the leaf area under observation, while a mobile sensor captures the image. From this capture, an in-built software counts the number of pixels in the image to finally detect the length and width of the leaf.

6. Why leaf area measurement is important?

The measurement of leaf area plays a crucial role in Agricultural, Botanical and Forestry research to study the effect of varietal characteristics on crop health. In Horticulture biology, this technique is used for breeding of naturally selected plants that show increased leaf size or better health. This method also plays a role in environment monitoring where the parameters of climate change and pollution levels are indicated by leaf area measurement.

7. Why you should use a leaf area meter over manual measurement techniques?

A leaf area meter reduces the chances of human error by improving precision of measurement, reduction in time and facilitating non-destructive, in-situ analysis allowing you to measure the area of the leaf without causing harm to the plant.

8. What is the latest technology used in these meters?

Currently, these modern devices make use of three distinct technologies, that is, Flatbed Optical Scanning which makes use of a light source and a mobile sensor, Laser Scanning that uses a reflecting laser beam and imaging sensor and Digital Camera-Based which utilizes a ultra-high-resolution camera to form a digital image of the leaf under observation.

9. What are the different types of leaf area meters?

On the basis of mobility, it can be of two types, that is, Stationary leaf area meters and Portable leaf area meters. The former is used for quality control and research purpose in controlled laboratory settings having limited mobility, whereas the latter is used in outdoor environments for quick assessment due to its small size.
