Specially developed for flexible use on construction sites and in the workshop, oxygen analyzer facilitate the welding of stainless steel, since the oxygen concentration can be displayed with an accuracy of up to 0.0005% (5 ppm). Before taking measurements of the welding environment, the oxygen analyzer must be calibrated according to the normal oxygen concentration in the air (20.9%).
The meter maintains calibration even if the device is turned off in the meantime. It is important to ensure that the calibration is repeated at regular intervals. The instrument has built-in temperature compensation to guarantee reliable measurement results at the respective working temperature. Large, unexpected temperature changes can change the measurement results until the temperature of the sensor has stabilized.
