Fast, Reliable Gas Leak Detection for Residential and Industrial Systems

SKU: 0563 0513

The Testo 513 Gas Leak Detector is a compact and reliable instrument designed for fast detection and precise localization of flammable gas leaks. It detects methane, propane, butane, and hydrogen, making it suitable for technicians working on residential and industrial gas boilers and similar systems.

With a response and recovery time of less than 2 seconds, the testo 513 quickly identifies even small leaks. Its flexible gooseneck probe, adjustable display modes, and automatic zeroing function make pinpoint leak localization fast and straightforward.

The user-replaceable sensor helps minimize downtime and reduce operating costs, making the testo 513 a practical choice for everyday professional leak detection.

Key Features

  • Detects methane, propane, butane, and hydrogen leaks
  • High sensitivity of 3 g/a for detecting small leaks
  • Fast response and recovery time of less than 2 seconds
  • Flexible and robust 330 mm gooseneck probe for easy access
  • Selectable numeric and bar graph display modes
  • Automatic zeroing for fast pinpoint leak localization
  • Manual zeroing option for individual adjustment
  • Optical and audible leakage alarms
  • User-replaceable gas sensor to minimise downtime
  • Compact and lightweight design for everyday professional use

The testo 513 combines rapid gas detection with practical features designed for professional service work. The flexible probe allows technicians to access difficult-to-reach areas, while selectable display modes provide clear information during leak detection.

Why It Matters

Flammable gas leaks can create serious safety risks in residential and industrial gas systems. Fast and accurate detection is essential when inspecting:

  • Residential gas boilers and heating systems
  • Industrial gas boilers and equipment
  • Gas pipes and connections
  • Gas appliances and installations
  • HVAC and gas servicing applications
  • Maintenance and safety inspections

The testo 513 helps technicians locate leaks quickly before they become a greater safety or operational concern.
