Product description: QT-ML3 portable soil moisture/temperature meter can be used for the measurement of moisture of various types of soil and media, and it can be used as a basic tool for on-site observation or mobile measurement. QT-ML3 Portable soil moisture/temperature meter Principle Using FDR (frequency domain reflectometry) principle, the sensor emits electromagnetic wave with a certain frequency, the waves transmit along the probe till they reach the bottom of the probe and return to

Descriptions: 4 Choice Insect Olfactometer is an instrument applied in studying the behavior of insects with strong ability of activity. Insets communicate with the host plant via odor about the information of spawning, feeding and other activities, so odor is very important for insects. The insects’ olfactory behavior could reveal the chemical relationship between pest and host plant, and could also provide a new way to the prediction, monitoring and prevention of pests. QT-WII01 4 Choice

Product description: Equilibrium tensiometer is a new revolutionary soil water potential meter which has patent protection. Soil water potential is measured as potential energy per unit quantity of water under isothermal conditions, its unit is bar (1 bar = 100kPa). In the soil, water potential is a major factor in determining the direction and speed of water flow, which is the only index of the effectiveness of soil moisture to plants. The water potential of different soils can be compared with

Product description: QT-SM100 soil moisture meter 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 moisture data can be transmitted to a handheld Android terminal by WIFI. QT-SM100 soil moisture meter Feature GPS coordination can be
