Multiparameter pH conductivity PC7 + DHS Kit
The pc7 + DHS mutliparameter, proposed by Agritechstore, is an elegant and ergonomic IP 57 watertight container, with a practical soft rubber shell, containing the best electronics and a large clear display with all the necessary information on the measurement, on the status of the electrode and on the memory of the instrument. Only 4 keys for the PC 7+ DHS allow you to manage all the functions in a simple and intuitive way. A practical standard USB output, adequately protected to guarantee watertightness, allows you to download data from the memory with the dates of the last calibrations performed, to power the instrument with a USB socket on a computer or with its 220V / USB power supply unit supplied with series. All functional parameters of the electrode connected during measurements or during calibration are constantly kept under control and in case of errors reported to the operator.
Furthermore the PC7 + DHS multi-parameter is equipped with intelligent sensor management. Digital High Sensor, are the new pH sensors with internal chip that store the parameters, the date of the last calibration, the model and the production lot of the electrode. A special chip with the same technology was inserted in the PC 7+ DHS. After connecting the DHS pH sensor to the instrument, all data stored in the sensor chip is automatically transferred to the instrument. The display will appear in sequence: DHS, the sensor model, the production lot, the date of the last calibration and the slope. After a new calibration of the DHS electrode, the data is automatically saved in the electrode chip. If we move this electrode to another instrument with DHS technology it will be possible to start working immediately and with extreme safety as the data of the last calibration will be automatically transferred and used for pH measurements. The new DHS pH sensors do not have an internal battery, so they can be stored as a normal pH electrode and do not use special connectors, but a normal BNC.
Many manufacturers using digital sensors have developed dedicated tools for these sensors. This requires a complete range of digital sensors for the various applications or needs of a laboratory. Our research and development team has designed this new line of instruments suitable for working both with the new DHS digital sensors and with normal analog pH sensors of all brands, which can always be connected to the same input as the pH meter. From today the pH measurement will be simpler.
