Home gas alarms are the first line of defense for household safety. Their core mission is to accurately sound an alarm before gas leak concentrations reach dangerous thresholds, preventing disasters. However, the unique cooking environment in Chinese kitchens—the volatile ethanol and acetic acid emitted by cooking wine and balsamic vinegar, as well as the high-temperature fumes from steaming and frying—often leads to frequent false alarms in traditional gas alarms, which not only annoys users but also seriously undermines their trust in product reliability.

    The root cause of these false alarms often lies in the performance limitations of the core gas sensor: poor interference resistance, weak environmental adaptability, and insufficient long-term stability. Therefore, selecting a high-performance sensor is key to completely solving the problem of false alarms and improving product quality.

ZR07 Hot Wire Gas Sensor

    The Tensensor ZR07 hot-wire gas sensor, designed specifically for complex kitchen environments, has become the preferred solution for high-end home gas alarms with its exceptional accuracy and stability.

Core Technology Principle

    The ZR07 utilizes the classic hot-wire catalytic combustion principle and consists of a precisely matched pair of test and compensation elements. Its operating mechanism is scientific and reliable:

    Precise Detection: When combustible gas comes into contact with the catalytic material on the surface of the test element and burns, the element's resistance changes due to temperature fluctuations, causing the Wheatstone bridge to lose balance and generating an output voltage signal proportional to the gas concentration.

    Intelligent Compensation: The compensation element acts as a reference, effectively offsetting interference caused by non-target factors such as ambient temperature and humidity, ensuring highly accurate and stable measurement results.

Why is the ZR07 the high-end choice?

    Extreme Interference Resistance, No More False Alarms

    Leveraging its grid-distributed MOS nanopore ultra-stable structure and pinned catalyst doping technology, the ZR07 offers exceptional resistance to poisoning by silicon compounds and H₂S, and effectively resists common cooking interferents such as oil smoke, ethanol, and acetic acid, significantly reducing false alarm rates.

    Stable Performance, Reliable and Durable

    The product boasts a stable structure, excellent output signal linearity and repeatability, and combines high precision and sensitivity with the long life of traditional sensors, ensuring minimal performance degradation over time.

    Comprehensive Compliance and Quality Certification

    Designed to meet the stringent requirements of China's latest standard, GB 15322-2019, for household combustible gas detectors, ensuring your product easily passes testing and certification.

    Exceptional Value for Money, Market Competitiveness

    By combining high-end performance with reasonable cost, we help brand customers create more competitive products and address the core pain points of failing spot inspections and user complaints.

    In short, the Tensensor ZR07 is more than just a sensor; it's a reliable "safety guard." Through cutting-edge material science and hardware design, it perfectly balances accurate detection with an extremely low false alarm rate, providing an unquestionable ideal solution for high-end household gas alarms.

    Choosing the ZR07 means choosing peace of mind, quality, and trust.
