The soil rapid tester is a rapid tester developed by our company for rapid detection of soil temperature, moisture content, EC conductivity, PH and other parameters. The rapid tester adopts a hand-held design, which is convenient for users to carry. The probe adopts a needle-shaped probe design and is made of stainless steel, which has good corrosion resistance and toughness. The rapid tester uses FDR technology to measure soil moisture and AC detection technology to measure EC conductivity. The product has high measurement accuracy and fast response speed. The soil fertility is indirectly reflected by measuring the conductivity content in the soil, so as to infer the trend of nitrogen, phosphorus and potassium content. The low-power LCD screen is used to display the measured values, which is concise and clear. The product is powered by three ordinary ordinary No. 5 batteries, which are easy to replace. The overall low-power design of the product can be used continuously for up to two years with three No. 5 batteries.
The temperature and humidity sensor uses an integrated temperature and humidity probe as a temperature measuring element to collect temperature and humidity signals. After circuit processing, it is directly output through the 485 interface of the main control chip. The probe type temperature and humidity sensor uses an imported digital temperature and humidity data acquisition module, which has been accurately calibrated at the factory. The relative humidity and temperature sensors have digital outputs and can be fully converted. They are outstanding in terms of measurement accuracy, linearity, repeatability, conversion, consistency, etc. It is suitable for environmental equipment matching, instrument equipment integration, and other general environmental tests.
The relative humidity of air is the ratio of the absolute humidity in the air to the saturated absolute humidity at the same temperature, and the result is a percentage. (That is, it refers to the percentage of the amount of water vapor in the air at a certain place to the saturated water vapor at that temperature within a certain period of time), expressed as RH. The rail-type temperature and humidity sensor uses imported digital temperature and humidity sensors, which have been finely calibrated during production, and the calibration data is stored in the internal memory. The relative humidity and temperature sensors have digital outputs and can be fully converted. They do not require complex verification and calibration processes. They are outstanding in terms of measurement accuracy, linearity, repeatability, conversion, consistency, etc. They are suitable for environmental equipment matching, instrument equipment integration, and general environmental testing.
