Historical data: In measurement status, press the “Store” key, and the secondary meter will store the |
measured oxygen concentration value and temperature value automatically. |
Multi-parameter display: Display oxygen concentration value, input electric current, temperature, time, status |
simultaneously. |
Calibration modes: In addition to the traditional one-point and two-point calibration, there are also manual |
zero point and slope inputs as well as the known oxygen concentration value calibration and other methods to |
meet the needs for the use in all circumstances. |
