Amphenol Advanced Sensors Telaire T3400 Series Refrigerant Leak Detection Sensor

Reliable thermal conductivity-based detection for modern systems

The Amphenol Advanced Sensors Telaire T3400 Series Refrigerant Leak Detection Sensors provide advanced, long-term monitoring for refrigerant gas leaks using thermal conductivity measurement technology.

Unlike traditional detection methods, the T3400 Series leverages a micro TCD (Thermal Conductivity Detector) sensing element to identify changes in gas composition with exceptional accuracy and speed. When refrigerant concentration in the air shifts, the sensor detects variations in thermal conductivity, enabling precise leak detection even in demanding environments.

Compact, durable, and engineered for a 15-year operational lifespan, the T3400 Series delivers dependable performance for HVAC and refrigeration safety and efficiency.
