Description
Overview
GAOTek Handheld Nutrient Soil Quality Tester adopts the latest digital integrated circuit technology and international testing technology to design a brand new intelligent handheld tester. The recorder uses a large-size full-colour LCD display that can display the readings in real time. At the same time, it uses the detection circuit designed by the digital chip of an international manufacturer, which can achieve very high sensitivity and excellent repeatability, and the recorder is integrated Storage, recording, and analysis are integrated, and it can be flexibly connected to soil ph sensors, soil electrical conductivity, soil temperature and humidity and other equipment to realize the measurement of various soil parameters.
Features
- Measurement results can be displayed directly
- A variety of recording methods are optional
- Large-size colour display screen, large-capacity storage
- One-key export of data, convenient and quick
- The probe plug-in design ensures accurate measurement
