Product description： QT-AT 502 Chlorophyll Meter can measure chlorophyll content of plants. Chlorophyll content is an important index of plant growth. This instrument is powerful, portable, and easy to use. It does no harm to plants. Users just need to put a leaf tissue larger than 3mm in the aperture, and then press the button to get the chlorophyll content reading.
QT-AT 502 Portable Chlorophyll Meter
Features:
· The measurements can be designated to up to 500 plant names;
· With a
Product description: Surface runoff is the flow of water that occurs when excess water from rain, meltwater, or other sources flows over the earth's surface. This might occur because soil is saturated to full capacity, or because rain arrives more quickly than soil can absorb it. Surface runoff is a major component of the water cycle. It is the primary agent in soil erosion by water. QT series tipping bucket flowmeter can be used to monitor no-pressure, low-head, and small discharge flow of
Product description: QT-SM101 is based on TDR (Time domain Reflectometry) technology, it can be used to rapidly measure the moisture of various types of soils. By measuring the dielectric constant of soil or other media, the meter can calculate soil water content, because soil water content is closely related to the dielectric constant. Soil temperature is measured via high-precision thermistor. Soil moisture and temperature data can be transmitted to a handheld Android terminal by WIFI.
