View Product Description
Portable Telescopic Handle SF6 Quantitative Leak Detector | 0.01ppm Sensitivity, Oil-Lubricated Pump 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:
  1. It adopts a telescopic handle design, making it convenient for movement.
  2. The continuous usage time of the lithium battery is approximately 50% longer than that of the LF-301.

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.

The sensor has no loss, with a long service life of 5 to 10 years. There is no radiation source, making it safe and reliable.

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.
Alarm Setting Range Any integer alarm value can be set within the measuring range
