Ａ・Ｒ・Ｐ Product Lineup

At A.R.P. Co., Ltd., we handle the "Soil Moisture Sensor Series." Starting with the "WD-3 Series," which is priced for cost-effectiveness due to its three types of sensors, we also offer the compact "WD5 Series," which includes an internal accelerometer. Additionally, we provide products such as the agricultural cloud service "agrinet" and the "Happy Minder," which offers robust support for greenhouse management. 【Features】 <WD-3 Series> ■ Priced for cost-effectiveness with three types of sensors ■ Long-term soil embedding possible (waterproof function equivalent to IP68) ■ No calibration required ■ Compatible with digital I/F ■ Adaptable to various environments such as greenhouse cultivation, open-field cultivation, and plant factories *For more details, please refer to the PDF materials or feel free to contact us.

• Sensors

Dedicated for K-type thermocouples Up to 6 slave units can be connected Multi-point measurement with a maximum of 12 channels Battery operated

• Temperature and humidity measuring instruments

When the pattern that occurs on the serial interface matches the trigger pattern, this product outputs a trigger signal to the oscilloscope, allowing for synchronized waveform observation on the oscilloscope.

• Other measurement, recording and measuring instruments

Conventional methods for measuring the concentration of contaminants in soil were only possible under specific soil moisture conditions. However, the development of this probe has made it possible to measure the temporal changes in contaminant concentrations in soil where moisture levels fluctuate due to rainfall and evapotranspiration. Technical Overview: This technology focuses on the changes in the soil's relative permittivity, volumetric heat capacity, and electrical conductivity when organic solvents are mixed into moist soil. It estimates the concentration of organic solvents in the soil based on the volumetric water content derived from relative permittivity and volumetric heat capacity, as well as the electrical conductivity measured by TDR.

• Other FA equipment

- Adoption of a unique circuit using a folded-back parallel transmission line method (patented) simplifies the circuit and improves cost performance. - By incorporating a CPU, it is possible to correct the detection signals from the sensor section and output them externally. * The characteristic data for volumetric water content (VWC), electrical conductivity (EC), and temperature is linearly corrected and outputted. (WETC type) * The electrical conductivity (EC) is converted to the value at 25°C (temperature compensated) and outputted. (WETC type) - A stabilized power supply is built into the sensor, allowing the supply voltage to the sensor to be used over a wide range of 4.5 to 15V.
