After the measured data stabilizes, the reading is automatically locked, and continuous reading is also possible. If there is no keyboard operation for 5 consecutive minutes, the meter will automatically shut down, and the long-term continuous reading function can also be set as needed. It has a one-button calibration function, and the user only needs to operate a single button, and the meter will automatically guide the completion of single-point or multi-point calibration. The large-screen LCD display can switch between pH, millivolt or temperature readings.
