7PID 系列的附加特点

1、超高灵敏度：灵敏度同样达到竞品 6 倍，仅需 5G 欧姆电阻即可实现 ppb 级分辨率（竞品需 20G 欧姆），基线更低更稳定。

2、稳定性能：性能稳定周期可达 4 系列 PID 的约 4 倍，保持灵敏度显著稳定。

3、长效寿命：独家无电极 UV 灯抗污染、易点火。与 4 系列相比，7 系列内置大型 UV 灯寿命延长约 5 倍。

4、维护优化：7 系列晶体尺寸为 4 系列的 4 倍，维护需求更少且环境适应性更优。灯体玻璃容器内惰性气体容量超 4 系列 20 倍，显著延长寿命并提升灵敏度。

Highlights（7PID）:

1. Superior Sensitivity: Our PID's sensitivity is 6 times greater than competitors, requiring only a 5 GOhm resistor for ppb resolution, as opposed to competitors’ 20 GOhm resistors. This results in a lower and more stable PID baseline, as well as an improved Signal-to-Noise Ratio compared to the 4-Series PID sensors.

2. Stable Performance: It maintains much more stable sensitivity for about 4 times as long as the 4-Series PID.

3. Extended Lifespan: Our proprietary non-electrode UV lamps have a longer lifespan, free from contaminants, making them easier to ignite. Compared to the UV lamp built in the 4-Series PID sensors, the much larger UV lamp embedded in the 7-Series PID sensors has a lifespan about 5 times longer.

4. Less Maintenance Required: The 7 Series has a crystal size 4 times larger than the 4 Series, requiring less maintenance and providing better environmental performance. The rare gas volume inside the lamp glass envelope is more than 20 times that of the 4 Series, leading to a longer lamp lifespan and higher sensitivity.

产品应用

PID室内空气质量检测等场景。传感器主要用于挥发性有机化合物（Senovol 产品凭借高分辨率、长寿命等特点，特别适合对检测精VOCs）等气体检测，适用于环境监测、工业安全、度和稳定性要求高的应用场景。与 4 系列 PID 传感器相比，7 系列的信噪比也进一步改善。

Product Application

PID sensors are primarily used for the detection of gases such as volatile organic compounds (VOCs), making them suitable for applications including environmental monitoring, industrial safety, and indoor air quality testing. With features like high resolution and long lifespan, Senovol products are particularly well-suited for scenarios demanding high detection accuracy and stability. Compared to the 4-Series PID sensors, the signal-to-noise ratio of the 7-Series has been further improved.
