SEM339 Multi-parameter sensors are products independently developed by our company. They all use imported data acquisition chips, advanced production technology and surface mount technology, and the measurement data is accurate and reliable. It has been finely calibrated during production, and the calibration data is stored in the internal memory. It is outstanding in measurement accuracy, linearity, repeatability, reciprocity, consistency and so on. In addition, the sensor has the characteristics of digital output, which can be fully interchanged, and does not need to undergo complex verification and calibration. It is suitable for environmental equipment matching, instrument equipment integration, and a large number of general environmental tests.
