In some relatively closed operating spaces, such as cabins, basements, underground pipelines, etc., due to poor air circulation and insufficient oxygen supply, hypoxic poisoning accidents are prone to occur. Therefore, personnel working in cabins, basements and underground pipelines need to be equipped with an oxygen alarm to warn the concentration of oxygen in the environment at all times. However, when we choose the oxygen alarm, we do not just find a manufacturer to buy it, but we need to know our own situation before we can choose the right oxygen alarm. Do you know what you need to know before selecting Oxygen Alarm ? The following is an introduction by Yi Yuntian:

Before selecting the oxygen alarm, need to know the following clearly:

1. Know Your Needs

Select an oxygen alarm need to clearly indicate which gas to use, which environment to use, portable or stationary, and other additional features.These reasons are usually factors that must be considered, otherwise it is easy to cause unnecessary economic losses.

2. Understand the origin of the sensor

many oxygen alarms the manufacturer's sensors are nominally foreign sensors, but that's not entirely true. Some use domestic sensors to imitate imported sensors to deceive consumers. In this case, carefully check the product information and, if necessary, sign a sales contract to protect your rights and interests.

3. Know the site safety situation

4. Understand the functional requirements used

the general function of the alarm is to detect the gas concentration and exceed the standard alarm. But many customers need more than just these features. Signal output is one aspect and requires current output, digital signal output, voltage output and switching output. There may be other special requirements, such as network interfaces and wireless signals. At the same time, data recording and processing are also common requirements.

5. Understand the working conditions of the environment

oxygen alarm, all kinds of gas detectors have strict requirements on the field environment. Generally speaking, the temperature is -20~50°C, the humidity is 0-95% RH, etc., including dust, flow, etc. Because other impurities in the environment may have a huge impact on the test results, resulting in unforeseen losses. At the same time, understand the working conditions of the site and provide the information to the manufacturer in time, and the manufacturer will have corresponding solutions.

To sum up, we can see that before choosing an oxygen alarm, we need to understand the requirements, sensors, on-site safety, functional requirements, and environmental working conditions. As long as we understand these situations clearly, in order to better choose the appropriate oxygen alarm according to your actual needs.
