Metal Lambda O2 Sensor BN TNT Compatible

A newly manufactured lambda oxygen sensor built for compatibility with BN251, TNT25, and TNT250 gas detection systems. Constructed from durable metal with a black finish, it replicates the physical form factor and mounting interface of the original units. Typical weight is ~120 g; overall length approx. 115 mm with M18×1.5 threaded body. Designed for direct bolt-in replacement in fixed gas analyser installations. No integrated electronics — functions as a standalone electrochemical sensing element requiring external signal conditioning.Intended for use in non-automotive, stationary gas monitoring applications where precise lambda measurement supports safety-critical or process-control decisions.
