InternalTemperatureProbes(Optionalnotonallmodels)
If the autoclave is fitted with two internal temperature probes. To change these probes you must remove the                 
side panel and unscrew the glands in which they enter the chamber. The probes are ‘K’ type thermocouple                 
autoclave type and are connected to an external plug for monitoring by chart recorder or computer or P.L.C.                 
Included is two blank plugs which you can screw into the vessel if you do not wish to use the internal                    
