How to Choose a Suitable Gas Detector for High-Humidity Environments

We have a client primarily engaged in production maintenance assistance, anti-corrosion insulation, equipment dry ice cleaning, and decoration projects. Their main business covers steel plants, steel pipe and section steel divisions, cold rolling mills and silicon steel departments.

The devices the client most frequently needs for daily operations are four-in-one gas detectors and carbon monoxide detectors. They are particularly concerned about waterproof performance. The client had previously purchased several four-in-one detectors, but most of them malfunctioned after a short period of use, significantly disrupting their work. The failures were largely due to motherboard corrosion, and the cost of after-sales repairs was high. Additionally, diagnostic reports were often required, which increased expenses and delayed project progress.

After understanding the client's actual working conditions, we recommended the MST410 model. This device has an IP66 protection rating, offering excellent waterproof, dust proof, and shock-resistant performance. It is also equipped with a sturdy clip, allowing on-site workers to securely attach it to clothing pockets or belts for continuous protection while working. Furthermore, the instrument's motherboard is specially treated with a conformal coating (moisture, mold, and corrosion resistance), effectively addressing circuit board corrosion issues in high-humidity environments.

Initially, the client was somewhat skeptical about the waterproof performance of the MST410. We patiently explained that the detector is fully waterproof and emphasized that the key to evaluating waterproof performance lies in identifying any exposure risks, particularly at the charging port. The MST model features a contact-based quick-connect design, reducing the risk associated with traditional exposed USB ports and significantly lowering the probability of moisture entering the device and corroding the motherboard. At the same time, this device comes with data storage and Bluetooth functionality, making it easy to identify and resolve issues promptly, thereby preventing gas leakage risks.

Additionally, as the client operates in the steel industry, they need to monitor CO concentrations in real time. They immediately took a liking to the MST101 model, noting that it closely resembles the instruments previously provided by their employer. We informed the client that this model is indeed widely used in the steel industry. It is a maintenance-free single-gas detector, compact and portable, with a motherboard treated with a protective coating for excellent waterproof and anti-corrosion performance. Moreover, the device is equipped with an OLED color display, which the client greatly appreciated. In the end, the client decided to purchase several MST410 and MST101 units for testing. A month later, they expressed high satisfaction, replaced all their detectors with our products, and even invited us to their factory for a diagnostic assessment to explore the possibility of establishing a better system linkage mechanism for their monitoring system. As a result, we embarked on a deeper collaboration.
