EMPOWER YOUR GREEN THUMB -- With the GYJ-C 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. Add to Cart Now.
