Leak detector with clamp for enclosing a section of pipe

A leak detector, comprising;

• a probe head comprising one or more probe head ports;
• a gas sensor in fluid communication with said one or more probe head ports having a first communication direction for the gas sensor;
• and
• a purge gas supply in fluid communication with said one or more probe head ports having a second communication direction for the purge gas supply,
• wherein the first and second communication directions are opposite to each other,
• wherein the gas sensor and the purge gas supply are configured for communication through a common conduit for the fluid communication with the one or more probe head ports, and
• wherein only one of the gas sensor or the purge gas supply can be in the fluid communication with the one or more probe head ports of the probe head at a time such that the common conduit and one of said one or more probe head ports are used for purging by the purge gas supply or detecting by the gas sensor,
• wherein the probe head comprises one or more probe head ports and a clamp arranged for shifting between an open position for receiving a pipe section and a closed position for enclosing the pipe section and forming a chamber around the pipe section in the closed position,
• wherein at least one of said probe head ports opens into an inside of the chamber,
• wherein the probe head comprises one or more activation points for shifting the clamp from the open position to the closed position by interaction with the pipe section, the activation points being configured for mechanically activation of the clamp by an applied force applied to at least one of the activation points, wherein the clamp is gradually closed as a function of the magnitude of the applied force.
