Handheld Soil Moisture Tester

I. Device Introduction

Our company's handheld soil moisture rapid tester is a newly developed intelligent handheld detection instrument, designed using the latest digital integrated circuit technology and international detection technology. The recorder features a large full-color LCD screen for real-time reading display. It utilizes detection circuits designed with digital chips from leading international manufacturers, ensuring extremely high sensitivity and excellent repeatability. Additionally, this recorder integrates storage, recording, and analysis functions. It can flexibly connect to our company's soil conductivity, soil temperature, and humidity devices, as well as our soil NPK (nitrogen, phosphorus, potassium) storage unit, enabling the display and storage of multiple soil parameters.

This recorder is widely used in dryland water-saving irrigation, precision agriculture, forestry, geological exploration, plant cultivation, water conservancy, environmental protection, and other fields.
