TLD 7103 Reader

This device is used for measuring absorbed dose in tablets or powder. The TLD 7103 consists of a simple drawer with a platinum plate. Tablet or powder is located on the plate (which is called planchet) and the device measures the diffused illumination of tablet or powder using related electronic boards by applying various thermal profiles and controlling consequent temperatures on the PMT. The element dose can be measured by diffused illumination.

The TLD 7103 reader is used in medical and health physics, material study and industrial applications.

 

TLD Reader Specification   

Key Characteristics

  • This device consists of a platinum plate which used for applying thermal profile to the tablets or powder; in this process the heat is controlled through a thermocouple that is welded under the plate precisely.
  • It contains a reference light for calibration.
  • Use of nitrogen gas to empty oxygen gas.
  • The maximum applied temperature is 400 °C.
  • It contains an anti IR filter for absorption IR frequencies generated from reader location.
  • It benefits supplementary software for TLD data processing due to using an independent computer.

 

Process of Acquiring Data From TLD Tablet Or Powder

  • Raw data and glow curve saving during acquiring time.
  • Warning if the read data be more than predetermined value.
  • PMT background and reference light check based on user demand.

 

TLD Thermal Profile Setting

  • Capability of 10 predefined time-temperature profile selection.
  • Capability of 4 range of interest on the glow curve.
  • Capability of changing the preheat time, preheated temperature, maximum read temperature, ramp of increasing temperature, time and temperature of acquiring, time and temperature of annealing.
