Long-lasting power: Two AAA batteries last longer, up to about 600 hours of continuous use. The instrument is equipped with low-voltage prompts to make it more user-friendly. When the battery is about to run out, a prompt will appear on the screen to remind the user to pay attention to the battery and replace the battery in time.
Automatic calibration: Two-point automatic calibration buttons of "0%" and "100%" are set up, which is convenient for calibration.
Temperature compensation function: automatically identify and convert the corresponding value under the difference between the actual solution temperature and the standard temperature to ensure more accurate measurement results.
