3) Leaf surface humidity: 0.0~99.9RH%;

4) Leaf surface temperature: -10~99.9℃

2. Measurement area: 2mm*2mm

3. Measurement accuracy: within 1 SPAD units (0.0-50.0 SPAD under normal temperature and humidity).

4. Repeatability within +-0.3 SPAD units (0.0-50.0 SPAD measurement position unchanged)

5. Data storage medium: Meter

6. Data storage capacity: About 2000 groups

7. Power: 4.2V rechargeable lithium battery (110V 60Hz with US plug)

8. Battery capacity: 800MAH

9. Product weight: 9.2 ounces (260g)

10. Product Size: 5.5 x 3.4 x 1.8 inches (140 x 85 x 45mm)

Working Principle:

1. Two LED light sources emit two kinds of light, one is red light (650nm), and the other is infrared light (940nm). Two kinds of light penetrate the blade and hit the receiver.

2. The light signal is converted into an analog signal. The analog signal is amplified and converted into a digital signal by an analog/digital converter.

3. The digital signal is processed by the microprocessor and the SPAD value is calculated and displayed on the LCD screen.
