some info about chlorophyll meter

Brief introduction of the meter:

The chlorophyll meter can instantly measure the relative content of chlorophyll (unit SPAD) green of plants; This gives an idea of the true nitro requirements of plants and helps you understand the extent of nitro deficiency in the soil or whether nitrogen fertilizer is applied too much. With this instrument, you can increase the use of nitrogen fertilizer and protect the environment (preventing the environment, especially water sources, from being polluted by applying too much nitrogen fertilizer).

The working principle of the chlorophyll analyzer:

Two LED light sources emit two kinds of light, one is red light (650nm), one is infrared light (940nm), two kinds of light penetrate the blade, hit the receiver, the optical signal is converted into an analog signal, the analog signal is amplified by the amplifier, converted into a digital signal by an analog/digital converter, and the digital signal is processed by a microprocessor, the SPAD value is calculated and displayed on the LCD screen.

We know that Konica Minolta's SPAD-502 is the best-selling chlorophyll meter in the world, but it is also expensive. After nearly 10 years of accumulation, according to long-term testing and customer feedback, we have been improving and upgrading, and now all aspects are mature and have been exported to many countries
