PCE Instruments 5856795 水质检测仪器

" PCE-PH20S-ICA Environmental tester incl. ISO calibration certificate For determining soil pH \/ External pH electrode \/ Recalibratable \/ Waterproof (IP 67)The Soil - environmental tester was developed to directly determine the pH in the soil. With the aid of this environmental tester , it is possible to quickly and accurately measure the pH of the soil or a solution thereof containing a soil sample. The soil electrode is inserted into the previously slightly loosened soil and the pH read on the digital display.Please always make sure that the measuring principle requires a minimum residual moisture in the soil. Thus, this soil environmental tester is the ideal solution for the accurate measurement of soil pH, in substrates, for horticultural irrigation solutions used in greenhouses and also in agricultural products and plants. The meter is always factory calibrated. A continuous recalibration of the pH meter is carried out by means of the supplied calibration standards (buffer solutions). The calibration data remains stored when the battery is changed. In general, you can simply pierce the electrode into the ground and read the pH directly on the digital display. If you would like to carry out a measurement according to DIN or if you can not penetrate deep enough into the soil due to soil hardness, then you should prepare a DIN soil solution and use it for the exact measurement.","**Care must be taken when inserting probe to not break it**"
