Huarui VOC detector from the United StatesIt can quickly, reliably, and accurately detect various VOCs under different temperature and humidity conditions, suitable for hazardous working environments with toxic/flammable gases, and can provide effective personal safety protection for on-site workers. Its application areas include emergency monitoring by petroleum, chemical, environmental protection, and fire departments, urban public utility safety testing, and hazardous chemical substance testing.

Maintenance measures:

1. Check the gas flow rate, usually 30/h, as excessive or insufficient flow rate can have a significant impact on the analyzer results

2. Replace filter paper: Stop the air pump and drain the filter tank

3. Check for any air leaks in the pneumatic system. Whether the diaphragm of the sobbing pump is damaged, whether the sealing ring of the sampling probe is broken, whether the four-way valve and condensate are damaged, etc

4. Cleaning of sampling probe, unblocking of sampling hole pipeline

5. Check if the condenser is working properly, usually adjust the temperature within the range of 3 degrees Celsius

6. Check the measuring room for dirt and clean it promptly.

Application in enclosed spaces:

When using in enclosed spaces, attention should be paid to flammable and harmful gases such as reaction tanks, sewers, shipping tanks, underground facilities, and other environments. Testing must be conducted before entering a closed environment. In this case, due to the lack of air flow in a closed environment and slow gas diffusion, the gas distribution in different parts varies greatly, so a suction pump detector must be selected. For example, combustible gases have a lighter mass.

These gases are mostly distributed in the upper layer of enclosed spaces, with carbon monoxide having a mass similar to air and generally located in the middle of the enclosed space, while heavier gases (such as hydrogen sulfide) are located at the bottom of the enclosed space. In addition, considering the hazardous gases in enclosed spaces, the built-in suction pump should be used to perform non-contact long-distance detection of multiple gases. At the same time, it is convenient to carry and does not affect the work of workers, ensuring the safety of people entering enclosed spaces.

In addition, after entering a closed environment, it is necessary to continuously detect the internal gas to prevent personnel from leaking and changing the concentration of hazardous gases due to temperature and other conditions.
