Product Details
Precision Of 0.01ppm, Digital Display Of Concentration, High
Sensitivity, Portable Leak Detector LF-300
The LF-300 utilizes low-voltage ionization in a high-frequency
magnetic field, offering a radiation-free design for safety and
reliability. Engineered without vulnerable components, it ensures
minimal usage and maintenance costs, combined with long-term
durability. An optional external lithium battery inverter supports
field operations requiring mobile power.
Key Advantages
- Ultra-High Sensitivity: Detects leaks as low as 0.01ppm with
precise quantification.
- Portable Design: Lightweight detector (1.2kg) and compact main
unit, housed in an aluminum anti-collision case for field mobility.
- Reliable Performance: Fast response (<1s) and recovery from
contamination, suitable for high-concentration SF6 environments.
- User-Friendly Interface: Real-time visual and audio feedback via
touchscreen and buzzer.
