PONPE 494WS-TM เซ็นเซอร์วัดดิน Soil Temperature  and Moisture sensor  

Product Introduce

The newer generation of soil moisture, temperature 2-in-one sensor is a soil sensor developed with a new technical solution. It can measure soil moisture, temperature at the same time, and perform compensation calculations between parameters. This product can be used to measure the water content of saline-alkali land without being affected by the salt content of the soil and accurately measure the water content of the soil. Adhering to the company's consistent product quality, strong and durable. Imported epoxy resin, high-quality stainless steel, more resistant to acid and alkali corrosion, steel needle isolation, never electrolysis. It has multi-directional protection functions for power lines, ground lines, and signal lines to prevent damage caused by reverse connection and wrong connection. It added TVS, a transient protection diode, which has been protected against lightning.

Product Features
1. Easy measurement
Soil moisture and temperature testing are no longer limited to laboratories and professionals, and can be measured by inserting into the soil.
2. Low measurement cost
Compared with traditional laboratory measurement, this product has low cost, fewer steps, no reagents required, and unlimited testing times.
3. High precision
High accuracy, fast speed, can reach accuracy within 3-5%, increase stability.
4. Portable measurement Convenient to carry, can be read by inserting the soil, can grasp the soil condition at any time, make the soil fertility balanced, and reach the suitable growth environment of the plant

Product application

It is suitable for water-saving agricultural irrigation, greenhouses, flowers and vegetables, grassland pastures, soil measurement, plant cultivation,

scientific experiments, underground oil transportation, gas pipelines and other pipeline anti-corrosion monitoring.
