LF-302
The difference between LF-302 and LF-303 lies in that LF-303 adopts an oil-free vacuum pump, while LF-302 adopts an oil-lubricated vacuum pump.
Technical Specification Sheet
This product is an improvement and upgrade based on the LF-301 SF6 Quantitative Leak Detector:
This device is developed based on the principle of low-voltage ionization in a high-frequency magnetic field and includes one leak detection main unit. Its highest sensitivity can reach 0.01 ppm. It supports set-value alarm, and the alarm methods are buzzer sound reminders and changes in the concentration at the leakage point.
It has a portable telescopic handle design, which is convenient for movement.
The detector head is equipped with a PM1.0 filter screen to prevent micro-dust from blocking the probe, effectively preventing the performance degradation of the instrument.
Table 1 Technical Parameter Response Table
| Item | Technical Parameters |
|---|---|
| Vacuum Pump Type | Double-stage Oil Pump (Customized) |
| Measuring Range (SF6) | 0.01～10000ppm; (Recommended Optimal Detection Range: 0.01-100ppm) |
| Measuring Accuracy (Highest Sensitivity) | 0.01ppm(v) 1.0×10-8 |
| Presence of Radiation Source in the Equipment | None |
| Response Time | ≤ 0.5 seconds in an environment with ≥ 1ppm of SF6 |
| Recovery Time | ≤ 10 seconds in an environment with 99.99% of SF6; 1 second in an environment with 10% of SF6 |
| Indication Method | Direct display of ppm value and audible alarm. The ppm value is directly displayed on the tablet with a resolution of 0.01ppm; for example, 99.99ppm. The LCD digital display of the detector: The higher the leakage concentration, the greater the digital change. Buzzer prompt: The higher the leakage concentration, the greater the change in the frequency of the buzzer sound. |
