Handheld Plant Chlorophyll Tester Premium Portable Plant Nutrition Analyzer Perfect for Agricultural&Plant Enthusiasts   GYJ-A : Measurement index: chlorophyll, leaf temperature GYJ-B: Measurement index: chlorophyll, leaf temperature, nitrogen content, with uploading data software. GYJ-C: Measurement index: chlorophyll, leaf temperature, leaf surface humidity, with uploading data software. GYJ-D: Measurement index: chlorophyll, nitrogen, leaf temperature, leaf humidity, with software for uploading data.   Product Introduction: The plant nutrient analyzer can instantly measure the relative chlorophyll content, nitrogen content, leaf temperature and leaf humidity of plants. The four parameters are measured at the same time and displayed at the same time. It provides a basis for precise fertilization and irrigation of plants, so as to avoid waste and environmental damage caused by excessive fertilization. It is helpful to increase the utilization rate of nitrogen fertilizer and provide reliable soil and crop information for precision agriculture.   Product Features:   EMPOWER YOUR GREEN THUMB -- With the Hm-Yc Chlorophyll Meter in hand has a measurement range of chlorophyll 0.0-99.9SPAD, leaf surface temperature -10-99.9℃, you're not just growing plants, you're optimizing life! Measure chlorophyll, leaf temperature, and leaf humidity like a pro, whether in an agricultural setting or a university botany lab.   BOOST PRODUCTIVITY -- Say goodbye to guesswork! Use the meter's precise, The measurement accuracy is ± 3.0SPAD for chlorophyll, ± 0.5℃ for leaf surface temperature, instant measurements to drive smart, informed decisions. Chlorophyll repeatability was ±0.3 SPAD, but not leaf humidity ±0.2°C. This repeatability index can ensure a certain measurement reliability. It's not just about growing crops, it's about maximizing their quality and yield.   SAFE, GENTLE TESTING -- Your plants are precious. Our meter's non-destructive testing method lets you probe plant health without causing a speck of harm. It's like having a conversation with your crops.

Product Description Need to calibrate the weight before use         With the instrument in the powered-off state, place it horizontally. Remove all items from the instrument, then press and hold the "Species" button while simultaneously pressing the "ON/OFF" button once to power on the instrument. The instrument will emit a beep. Release the "Species" button, and the display will show the number "0.00," indicating that it is now in balance calibration mode. Press the confirmation button once; the decimal point on the display will blink, and the number "200g" will flash, indicating that the 200g calibration weight should be placed. Carefully place the provided standard calibration weight (or a 200g standard weight) on the black pointed tip at the center of the measurement sensor. Press the "OK" button once more. After the instrument displays the result, power it off to exit. Remove the calibration weight, and you're done.           moisture meter Trait metal sensor, displays measurement results in 2 seconds.
