Product Description

 Heat Release And Mass Loss Calorimeter

Description of Heat Release And Mass Loss Calorimeter
The 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 Controller
Load cell controller
Tare button
Control 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 base
  • Load cell – switches on the Newport controller
Specification
  • Manufactured from stainless steel for long life
  • Retainer edge frame stainless steel with inside dimension 111 × 111mm, and opening of 94 × 94mm
  • Three control thermocouples for the cone heater to maintain accurate heat flux
  • Special split shutter mechanism is designed to prevent heating of the sample before the test is started
  • Spark assembly is used in conjunction with the shutter mechanism. Microswitches are fitted to the spark arm and the shutter mechanism for safe operation
  • Sample weight measurement is by a strain gauge load cell with quick electronic tare facility
  • Specimen holder square pan 106 × 106mm at the top, and a height of 25mm, constructed from stainless steel
  • Sample size up to 100 × 100mm
  • Sample thickness up to 50mm
  • Balance sensitivity < 0.1g
  • Load capacity up to 2.0kg
  • Control unit contains switches for power, ignition, load cell and cone heater
  • Temperature controller for ramp and control of cone heater
  • 5kW electrical heating element
  • Heat flux up to 100 kW/m2
  • Heat shield placed between the cone heater and specimen
  • Load cell controller with weight ranging facility to improve performance to suit weight of sample (0-500g).
