About This Product
■Measuring equipment to measure the health of plants
This is a measuring instrument that indicates the amount of chlorophyll contained in plant leaves as a SPAD value (value indicating chlorophyll content), which is necessary to know the health level of plants. The chlorophyll meter can be measured instantly on the spot without the need to collect samples, and since it is waterproof, it can be measured even in the rain.
■Measures chlorophyll content quickly and non-destructively.
Simply place the leaf you want to measure on the measuring head and close it. There is no need to cut leaves, and the same part of the same leaf can be always measured during the growing process.
■Trend graphs can be displayed.
You can check time-series changes in measurement data and judge abnormal values at a glance.
■Handy and convenient to carry.
It is compact enough to fit in your pocket, making it convenient to carry outdoors. It weighs only 200g.
■Flash-proof design allows measurements even in the rain.
IPX 4 (class 4 protection against water ingress) allows measurements even in the rain.
■Energy-saving design.
By using a light emitting diode (LED) light source, it consumes less power and has a long life. Two AA alkaline batteries can perform over 20,000 measurements.
■Main uses
Fresh leaves of agricultural crops (mainly paddy rice)
