General Purpose Thermocouples

Autoclave Load Thermocouple (Type 9A)

The harsh conditions found in the autoclave chambers of sterilisers require a reliable sensor, as all too often sensors can fail and instrumentation be damaged through ingress of moisture. These autoclave load thermocouples offer a reliable solution to the problem.

Available in thermocouple types T or K, they can be supplied as simplex or duplex assemblies and comprise of a stainless steel sensor tip, a length of cable inside a flexible stainless steel conduit, a stainless steel feed-through and then flying leads oversheathed with silicone rubber. An Autoclave Drain Thermocouple is also avaialble.
