Combustible gas leak detector pen with telescopic probe up to 16 cm, adjustable sensitivity 50-500/500-3000 ppm, fast response in less than 2 seconds for methane, propane, and LPG

Detects a wide range of combustible gases: Safely identifies methane, LPG, propane, butane, petrol vapor, ethane, ethanol, and acetylene, helping UK households and tradespeople locate gas leaks around boilers, cookers, heaters, and pipe joints before they become dangerous.
Extendable probe for hard-to-reach areas: The flexible telescopic probe (5.6 to 16 cm) allows you to inspect behind appliances, inside cupboards, cellars, caravans, or narrow pipes without putting your face near potential leaks.
Fast response with clear audible and visual alarms: Detects gas in under 2 seconds (system warm-up time is approximately 30 seconds). As the concentration increases, the beeping becomes faster and the LCD bar graph expands; the screen turns red at higher levels for instant risk awareness.
Adjustable sensitivity for precise leak location: Switch between high (50 to 500 ppm) and low (500 to 3000 ppm) sensitivity modes to identify small leaks or scan larger areas efficiently during routine safety checks.
Compact, portable, and ready to use: The pen-style design with a pocket clip makes it easy to carry for homeowners, plumbers, and DIYers. Comes with 2 AAA batteries, a storage pouch, and automatic power-off after 5 minutes to conserve energy.
