One, LT-ZO zirconia oxygen analyzer features:
1. Zero and span independent compensation adjustment (advanced function) The general analyzer only has zero compensation and no span compensation. This makes it difficult to debug the zero point and span. After the zero point is accurately adjusted, the range cannot be adjusted. Or after the range debugging is accurate, the zero point cannot be adjusted. Causes debugging errors. Zirconia Oxygen Analyzer with zero and span independent compensation adjustment, that is, zero-point debugging is accurate, the range can also be adjusted accurately. This will increase the analyzer's measurement accuracy.
2. The burnout protection (advanced function) general analyzer does not have this function. Electric furnace damage will result. Zirconia Oxygen Analyzer with this feature, that is, the electric couple in the case of disconnection, automatic stop heating. It helps to protect the electric furnace.
3, program temperature (advanced function): General analyzer: direct heating method, that is, heating from room temperature to 700 degrees only takes about 5 minutes, due to the heating speed, the speed of cold and hot changes will be faster, will lead to zirconia The sensor is broken. The zirconia oxygen analyzer uses a program to heat up, that is, the CPU chip is used to control the heating rate, about 25 degrees/minute. This ensures that the zirconia sensor heats up to 700 degrees at a uniform rate. It helps to ensure the life of the sensor.
4, temperature compensation (advanced function) general analyzer does not have temperature compensation. In other words, different ambient temperatures in winter and summer cause heating temperature errors and seriously affect the measurement accuracy. The zirconia oxygen analyzer uses AD590 temperature compensation. That is, the error caused by the ambient temperature can be automatically corrected in winter or summer, which is beneficial to improve the measurement accuracy of the analyzer.
Second, zirconia oxygen analyzer installation note:
1. After using the oxygen probe for 8-10 months, it is better to re-calibrate it to determine the background value. No standard gas is determined according to the above method. It is better to use the standard gas calibration.
2. The main component of the oxygen analyzer is the integrated circuit. The working temperature of the integrated circuit cannot exceed 55°C. Therefore, the installation position of the oxygen analyzer should be selected where the ventilation is shaded, the rain does not reach, and the ambient temperature cannot exceed 50°C. .
3. The zirconium oxide probe must be slowly inserted into the flue during installation to prevent the zirconium tube from bursting when exposed to high temperatures. The oxygen probe junction box has two air inlets that must face downwards. One air inlet is the reference gas. The entrance is always open and cannot be blocked; the other inlet is the standard gas inlet and is normally closed. The test must be blocked before it can ensure the measurement accuracy.
4. When the oxygen probe is installed, flanges and flanges must be matted with asbestos mats, so there is no leakage, so as not to affect the measurement accuracy; the bottom of the oxygen probe is equipped with a white filter, and the dust is accumulated for a long time and the gas is affected. Transparency must be promptly replaced.
Therefore, it is necessary to make preparations before the operation. The preparation work in advance is conducive to the subsequent measurement. The so-called sharp knife does not mistakenly cut firewood. The above introduction hopes to help you, welcome to our company to buy products.
