TY-YLS chlorophyll analyzer

1、 Purpose:

Plant chlorophyll meter can measure the relative chlorophyll content of plants in real time (unit)SPAD）Or‘Green degree'This can help you understand the true nitrate demand of plants and help you understand the degree of soil nitrate deficiency or whether excessive nitrogen fertilizer has been applied. You can use this instrument to increase the utilization rate of nitrogen fertilizer and protect the environment (preventing excessive nitrogen fertilizer from contaminating the environment, especially water sources).

2、 Working principle

Working principle of chlorophyll meter

twoLEDThe light source emits two types of light, one is red light(650nm)One is infrared light(940nm)Two types of light penetrate the blade and hit the receiver. The light signal is converted into an analog signal, which is amplified by an amplifier and then converted into an analog signal/The digital converter converts it into a digital signal, which is processed by a microprocessor and calculatedSPADValue and display on the LCD screen.

Calibration and Calculation of Chlorophyll Meter Measurement Values

（1）During the calibration process, the pressure head does not clamp the sample, twoLEDSequential light emission, the received light is converted into electrical signals, and the ratio of light intensity is used for calculation.

（2）After clamping the sample with the pressure head, twoLEDOnce again emitting light, the light transmitted through the blades hits the receiver and is converted into an electrical signal, and the intensity ratio of the transmitted light is calculated.

（3）Steps1and2The value is used for calculationSPADThe measured value represents the current relative chlorophyll content of the clamped sample leaves.

4、 Operating instructions

1Turn on the power switch, and the LCD screen will display the current time.

2Press and hold the measuring head for calibration(No objects are allowed to be placed at the measurement location at this time)Until the LCD screen displaysb000This indicates that the instrument has been calibrated and can start measuring.

If the LCD screen displaysA - - -If the instrument cannot pass calibration, please check if there is an object blocking the measurement position below the measuring head. Otherwise, please refer to the troubleshooting operation.

3When measuring, please place the plant leaves in the measuring position and press the measuring head for two to three seconds. The display screen will automatically show the chlorophyll value of the measured leaves. Release the measuring head,

pressENTSave the measurement results to the keySDOn the card, if the data does not need to be saved, you can directly use the measuring head for the next measurement.

4After the instrument calibration is completed, you can use the ▼ key to view itSDThe storage status, battery level, and time settings of the card.

After the instrument calibration is completed, press the ▼ key for the first time and the display screen will show0001showSDThe data that the card is currently preparing to store is the first one. If the display screen shows- - - -Indicates no insertionSDCard, press the ▼ key again and the display screen will showU4.18Indicates that the current battery level is4.18VAt this point, pressing the ▼ key again will switch the display screen to the time interface, and the cursor will automatically flash. At this point, you can use ▲/▼ AndENTUse the key to modify the current time.

5、 Precautions

1Keep the measurement location clean to avoid affecting the measurement results.

2Regularly check the battery level, and when the battery level is below3.8VPlease charge it in a timely manner.

3Because this instrument measures the relative content of chlorophyll through infrared light, it is advisable to avoid direct sunlight during measurement and use a slight cover such as the body.

6、 Fault handling

1If the instrument fails to pass through each calibration, please clean the measurement position first and check if there is any object blocking the photoelectric sensor window. If there is no object blocking the photoelectric sensor window, please charge the instrument1Try again in about an hour to see if this phenomenon is caused by insufficient battery power.

If you are still unable to resolve this issue, please contact our customer service in a timely manner. Our customer service will assist you in resolving the problem!

2If the calibration passes but the measurement results deviate significantly each time, please check the battery level. If there is no problem with the battery level, please turn off the device5Restart and calibrate in minutes, then proceed with the measurement.

3If the instrument crashes, please press the paper clip into the reset hole on the right side of the instrument and press the reset button to restore normal operation.

Technical specifications (TY-YLS)
