CPS LSCG Leak-Seeker Combustible Gas Leak Detector

Leak Detection Made Easy With the Leak-Seeker

The LSCG Leak-Seeker is a hand-held, battery operated combustible gas leak detector for use by HVAC Pros, Plumbers, Pipefitters, Mechanical Contractors, Facility Maintenance, Factory Technicians, and other professional trades for installing or servicing equipment that uses combustible gas on residential, commercial, or light industrial jobs.

A key benefit of the LSCG is that it has 5 different alarms to help technicians quickly pinpoint leaks. For example, 3 different visual alarms show "gas concentration" on the large backlit display, while one vibration alarm and one audible alarm alert technicians when working in challenging jobsite conditions.

Key Features and Benefits

  • Detects Up To 30 Combustible Gases - Best in its class!
  • Large Backlit LCD Display - 1.5" x 2" (38 x 51mm) largest in its class!
    Visual alarms include:
    • Speedometer PPM Scale - Great for peripheral vision while searching for leaks.
    • PPM Readout - Large 1/2" numbers are more precise than detectors that show ranges
    • LEL % Readout - Large 1/2" numbers show what % of the lowest gas concentration that has the potential to be flammable or combustible.
  • High/Low Concentration Key - For detecting 10 to 1,000 PPM or 100 to 10,000 PPM
  • Long 20" (51cm) Flexible Probe - For hard to-reach areas
  • Ergonomic Housing with Intuitive Keypad - Simple icons or abbreviations
  • Auto Features (AC, APO, AZ) - Automatic Calibration at each power up; Auto Power Off if not used for 10 minutes; Auto Zero- resets the sensor
  • Rechargeable Lithium-Ion Battery - No need to buy or dispose of single-use batteries
