In the wild, handheld chlorophyll meter is very convenient to use. SPAD's measuring area is only 2mm × 3mm (thickness does not exceed 1.2mm), and for small blades, the measurement is also effortless. The center line indicates the center of the measured area. The launch window and the receiving window are indicated, and the depth stop allows the measured blade to be placed in the same depth.
1) The instrument is calibrated. Only the calibration can ensure the accuracy of the measurement result.
2) Put the blade into the measuring head. Please pay attention to the following points when operating this step:
a. Make sure the sample completely covers the receiving window.
b. Do not measure excessively thick samples, such as veins. If there are more samples with veins measured, measure and average them several times.
c. If the transmission window or receiving window is dirty and the measurement is inaccurate, clean it first.
d, avoid direct sunlight equipment, so as not to affect the measurement.
3) Close the measuring head and press the acupressure platform until a “click†sound is heard. The measurement results will be displayed on the screen and stored automatically.
If you hear continuous beeps, indicating that the probe is not closed tightly, or if the sample is too thick or too thin, repeat steps 2 and 3 until the end of the measurement.
If the displayed decimal point is flashing (or no decimal point), the measurement result is greater than 50 (100). The accuracy of the result is not guaranteed. ?

How to use the chlorophyll meter It is of great significance to measure the chlorophyll content in the leaves of plants by using the chlorophyll meter. We can understand the photosynthetic reaction rate of plants through the chlorophyll content, and we can also understand the plant through the chlorophyll content. In the absence of nitrogen, what is the use of chlorophyll timing? The following is a brief introduction.
