Product Details
Customized portable SF6 gas leak detection sensor, most suitable
for on-site leak detection LF-200
KStone is a participant in the development of the Chinese national
standard GB/T11023-2018;
KStone holds multiple invention patents for this type of product;
The LF-200 leak detector is most suitable for on-site leak detection;
The LF-200 redefines on-site SF6 leak detection as a cutting-edge
portable solution for identifying micro-leaks and slow leaks.
Compared to the LF-1D+, its enhanced portability makes it the
preferred choice for field inspections. The detector integrates
exclusive patented auxiliary startup technology, guaranteeing 100%
successful ignition. With a split-design architecture, it weighs
only 6.6kg, while a newly patented vacuum detection system
automatically optimizes operational conditions, delivering
intuitive user experience.
Key Features & Benefits:
- Minimal Maintenance: Engineered without vulnerable components to
reduce downtime and operational costs.
- Intelligent Operation: Activates auto-mode within 5 minutes of
vacuum pump startup, with real-time vacuum level monitoring.
- Contamination Resistance: A continuous air circulation mechanism
prevents dust and oil interference, ensuring rapid performance
recovery.
- Comprehensive Protection: Equipped with overheat protection,
anti-dust inhalation safeguards, and replaceable fuses for reliable
operation.
- Portability & Durability: Housed in a metal anti-collision case,
designed for frequent transport and rugged field use.
Leveraging low-voltage ionization technology in a high-frequency
magnetic field, the LF-200 achieves 0.01ppm sensitivity—setting a
standard for precision leak detection. Trusted by industry leaders
such as Henan Pinggao Electric and Xi'an XD Switchgear, it combines
split-portable design, patented innovation, and durable engineering
for professional field applications.
