How to use a portable oxygen detector
The portable oxygen detector is a gas detector used to detect the oxygen concentration in the environment. It is often used in various closed spaces. When used, it can simply and quickly detect the oxygen concentration in the environment so that we can better handle it. All kinds of security. So how to use a portable oxygen detector?
1. It is recommended that the portable oxygen detector be in natural contact with the air for more than 5 minutes after it is turned on. This is usually also called startup preheating. The main purpose is to fully activate the sensor performance, which can play a certain role in the response and performance of the instrument. accuracy.
2. It should be noted that the ambient temperature of the instrument during the detection process cannot exceed the range that the instrument can withstand. Portable oxygen detectors should be used when the ambient temperature is -20 to +50 degrees, the humidity is 95% without condensation, the atmospheric pressure is normal, and there is no large amount of gas dust. If the current environment does not meet the use conditions, it is necessary Shorten its measurement time to avoid affecting the sensor's service life.
3. An important issue in the process of operating the instrument is that it needs to be calibrated regularly. Generally speaking, it is calibrated once every 3-6 months. The calibration method is relatively simple. During the process of calibrating the instrument, the instrument can be calibrated with the help of air standard oxygen. , generally the standard oxygen content in every environment is 20.9, except for some special areas which may be around 20.7, so in our practical applications, instruments that can detect gases usually use this air environment as the calibration standard, and the instruments are calibrated regularly. Sensor drift or signal attenuation can be avoided.
The above-mentioned usage methods of portable oxygen detectors are shared with you here. Portable oxygen detectors are suitable for continuously detecting the percentage concentration of oxygen in the ambient air of industrial and mining enterprises. When the ambient concentration is high, perform high-limit, low-limit sound, Light and vibration alarms warn on-site personnel to evacuate the dangerous area as soon as possible.
