Heat Release And Mass Loss Calorimeter

Product Description

Heat Release And Mass Loss CalorimeterDescription of Heat Release And Mass Loss CalorimeterThe Heat Release apparatus measures time to ignition, mass loss and heat-release rate (option) of specimens exposed in the horizontal orientation to controlled levels of irradiance with an external igniter.On the front panel, the following are mounted: Temperature ControllerLoad cell controllerTare buttonControl switches comprising four red on/off push-button switches, which operate by firm pressure and light up when activated: Power switches on mains electricity to the unit Cone switches on the Eurotherm controller. This, in turn, energises a solid state relay, which switches the power to the cone heater (5kW) Ignition switches on the spark-generator circuit housed in the test chamber baseLoad cell switches on the Newport controllerSpecificationManufactured from stainless steel for long lifeRetainer edge frame stainless steel with inside dimension 111 111mm, and opening of 94 94mmThree control thermocouples for the cone heater to maintain accurate heat fluxSpecial split shutter mechanism is designed to prevent heating of the sample before the test is startedSpark assembly is used in conjunction with the shutter mechanism. Microswitches are fitted to the spark arm and the shutter mechanism for safe operationSample weight measurement is by a strain gauge load cell with quick electronic tare facilitySpecimen holder square pan 106 106mm at the top, and a height of 25mm, constructed from stainless steelSample size up to 100 100mmSample thickness up to 50mmBalance sensitivity < 0.1gLoad capacity up to 2.0kgControl unit contains switches for power, ignition, load cell and cone heaterTemperature controller for ramp and control of cone heater5kW electrical heating elementHeat flux up to 100 kW/m2Heat shield placed between the cone heater and specimenLoad cell controller with weight ranging facility to improve performance to suit weight of sample (0-500g).FeaturesFire model manufactured from stainless steel for long lifeThree control thermocouples for the cone heater to maintain accurate heat fluxSpecial split shutter mechanism is designed to prevent heating of the sample before the test is startedSpark assembly is used in conjunction with the shutter mechanism.
