제품특징

The TPP device features a heat source that consists of two propane burners and a 9-bulb quartz infrared heat lamp assembly. The system is automated by using a pneumatically actuated sample carriage, water-cooled shutter, and a mass flow controller. Additional benefits include three thermocouple inputs and an integrated sensor cooling stand for improved testing through-put.
System includes PC laptop computer with ThermDAC data acquision and control system with burn prediction.
