Explosion-proof oxygen analyzer
Brief description:
The explosion-proof oxygen analyzer is equipped with a nitrogen control box, which automatically cuts off the large flow rate when the oxygen concentration value is within the safe range to achieve continuous supply of small flow rate to meet the micro-positive pressure in the kettle.
Product features of explosion-proof oxygen analyzer:
1. Customized pretreatment: acid-base neutralization, organic matter removal, water removal, drying, voltage stabilization, constant current, etc. of sample gas; Safety: When the oxygen concentration value exceeds the preset alarm value of the first level, the electromagnetic nitrogen filling and replacement will be automatically turned on until the value drops to a safe range;
2. Nitrogen flow control: Equipped with a nitrogen control box, it automatically cuts off the large flow rate when the oxygen concentration value is within the safe range to achieve continuous supply of small flow rate to meet the micro-positive pressure in the kettle;
3. Applicable explosion-proof areas: intrinsically safe explosion-proof composite instrument, which meets the requirements of harsh use areas;
4. Signal acquisition: 16-bit ADC digital-to-analog conversion, which meets the requirements of trace oxygen data acquisition with higher accuracy;
5. Module platform: The pretreatment level and function adaptability can be freely adjusted according to the actual use situation, which has a wider range of adaptability;
6. Easy maintenance: one-key calibration/calibration, tool-free disassembly and maintenance, and hot-swap replacement of sensor components;
7.Intelligent display: self-luminous OLED display, multi-angle observation of wide.

Explosion-proof oxygen analyzer is a professional instrument used to detect oxygen content and other related parameters in the air. It is widely used in various industries, environmental protection, safety and other fields. This article will introduce the use of explosion-proof oxygen analyzer in detail.
Instrument Overview:
Explosion-proof oxygen analyzer is a professional portable instrument, mainly used to detect oxygen content and other related parameters in the air, with the following characteristics:
1.Adopting the latest microelectronics technology, the performance is stable and reliable.
2.Reasonable design, easy operation and accurate data.
3.Using explosion-proof materials and structures, it is suitable for explosion-hazardous occasions.
4.The conditions are widely applicable and can be applied to various industries.
Preparation before using the instrument:
1.Read the instructions and operation manual carefully to understand the performance and use of the instrument.
2.Confirm whether the instrument is in normal working condition, including whether the power supply is sufficient, whether the sensor is normal, and whether the external instrument is damaged.
3.Prepare the required accessories and auxiliary equipment, such as batteries, calibration gas, etc.
Instrument use steps:
1.Turn on the instrument switch and start the instrument.
2. Wait for the instrument self-test to complete and confirm whether the parameters and indicator lights on the display are normal.
3. Put the sensor into the air to be tested and wait for the instrument to detect the oxygen content.
4. When the instrument detects oxygen content, the sensor plug needs to be connected to the control host.
5. After waiting for a while, the instrument will display the oxygen content (unit: %) and other related parameters. If the oxygen content is detected to be beyond the set range, the instrument will sound an alarm.
6. During use, if you need to replace the battery or calibrate the gas, you need to follow the instructions in the operating manual.
Precautions:
1. When using the instrument, the instrument should be placed in the air for preheating to ensure accurate test results.
2.During operation, the instrument should avoid working with other electronic devices at the same time to avoid interference.
3. When moving the instrument, violent vibration and collision should be avoided as much as possible to avoid instrument failure.
4. After the instrument is used, it should be cleaned and maintained in time to ensure its accuracy and reliability.
5. When calibrating the instrument, the correct calibration gas and method should be used according to the requirements in the operating manual to ensure the accuracy of the test results.
Conclusion:
The explosion-proof oxygen analyzer is an important professional instrument for detecting the oxygen content in the air. There are some matters that need to be paid attention to when using the explosion-proof oxygen analyzer, including the preparation work before the use of the instrument, the use steps and precautions. The correct use of explosion-proof oxygen analyzers can effectively grasp the oxygen content in the working environment, thereby ensuring the life safety and work efficiency of personnel.
