Corrosion-resistant temperature and humidity sensors offer excellent resistance to corrosive agents and high temperatures, making them ideal for monitoring environmental conditions in demanding industrial settings. These sensors are essential in applications where standard devices would degrade rapidly due to exposure to acids, alkalis, steam, or elevated thermal loads. As a specialized manufacturer based in Beijing, Kunlun Zhongda has earned widespread recognition for its mature technology, rigorous quality control, and reliable product performance across diverse industries such as chemical processing, wastewater treatment, pharmaceutical manufacturing, semiconductor cleanrooms, and offshore energy platforms.

Our sensors feature independently developed anti-corrosion housings made from high-performance materials such as PPS (polyphenylene sulfide), Hastelloy, or specialized coated stainless steel, depending on the application. These materials provide exceptional resistance to chemical attack, oxidation, and mechanical wear, ensuring long-term stability and accurate, sensitive performance even in the most aggressive environments. The core sen sing element utilizes a proprietary high-temperature-resistant humidity-sensitive resistor, capable of withstanding continuous exposure to extreme thermal cycles. This is paired with advanced hardware circuitry and multi-point temperature compensation technology to eliminate drift and ensure consistent readings across the full operating range.

The innovative split (remote) design is a key differentiator: the sensing probe can be inserted directly into high-temperature pipelines or chambers—operating continuously at temperatures up to 260°C—while the transmitter unit is mounted in a cooler, standard environment. This separation protects sensitive electronics, enhances safety, and significantly extends service life without compromising measurement accuracy.

We provide comprehensive after-sales service and warranty support, including technical training, on-site troubleshooting, and calibration verification, to give our customers complete peace of mind. Superior product performance, long-term reliability, and thoughtful technical service have made us a sales leader among manufacturers of corrosion-resistant temperature and humidity sensors.
