gas detectorIt mainly consists of the sensor and the motherboard circuit of the device itself. We divide it into two parts. The first part is the sensor part, and the second part is the main part of the detector.
The service life of the sensor is fixed, and the service life of the sensor with different principles is different. For example, electrochemical sensors have a normal design life of two years and must be replaced at the end. Generally speaking, replacement time has little to do with the number of uses and storage time. Because electrochemical sensors have electrolyte inside, they naturally decrease during the sensor placement process, so they are consumed even if they are not used. Therefore, it basically has a fixed replacement cycle, once it expires, it needs to be replaced, so we recommend that users do not need to prepare sensor accessories in advance when using the detector, otherwise it will be a waste and loss.
The second part isgas detectorboard. From this point of view alone, a circuit with a reliable design and sufficient materials can basically guarantee the service life of the fuselage for 3-5 years. someportablegas detectorThere is a suction pump and a battery, which can be used for about 2 years.
To sum up, the Gas Detector's circuit board will not cause problems under normal use. Most cases of gas detectors are caused by faulty sensors, so the service life of gas detectors is equal to the life of the sensor. The service life of the electrochemical sensor is approximately 2 years. After 2 years, the performance of the instrument needs to be tested and then the sensor needs to be replaced.
Gas detection requires precise calibration when replacing sensors
Many gas detectors now have replaceable sensorsToluene alarm, but this does not mean that a detector can change the sensor at any time. Whenever a sensor is replaced, the instrument must be calibrated in addition to the aging sensor. Calibration requires the use of the appropriate standard gas.
In general, each sensor corresponds to a specific detection gas, but eithergas detectorNone of them can be absolute special effects. Therefore, when choosing a gas sensor, you should try to understand the detection interference of other gases on the sensor to ensure its accurate detection of specific gases.
What are the types of PortableGas Detector?
portablegas detectorIt is mainly divided into two types: diffusion type and pump type. Portable, as the name suggests, is designed to be portable, mobile, and flexible. When choosing, we need to consider what kind of portable instrument is suitable for his field of application.
portablegas detectorIt should have the following features:
1. Direct reading digital screen, which can quickly display the current gas concentration.
2. It has a record storage function, the sampling interval can be set, and the gas detector can automatically record the current concentration data as needed.
3. There are gas sounds, light exceeding standards and vibration prompts.
4. The use of rechargeable lithium battery or replaceable battery can ensure the power reserve for more than several hours of continuous use.
5. The weight and volume of the equipment are mostly portablegas detectors, and the volume is small.
