Thermal and Light Radiation | ThermoFlux – 7031
A CE-certified apparatus for measuring surface emissivity and verifying the Stefan-Boltzmann law of thermal radiation, manufactured by Scientico India to ISO 9001:2015 standards. Supplied with calibration certificate, operation manual, and complete export documentation. Designed for Thermodynamics Lab Equipment laboratories in engineering colleges and technical institutions.
The Thermal and Light Radiation ThermoFlux – 7031 is a comprehensive laboratory apparatus designed to demonstrate and experimentally verify the fundamental laws governing thermal and light radiation heat transfer. This Thermal and Light Radiation unit combines electrically heated radiant heat and light sources with a horizontal track system, interchangeable target plates, and a full suite of measuring instruments, enabling quantitative investigation of the Inverse Square Law, Stefan-Boltzmann Law, Kirchhoff’s Law, Lambert’s Law, and area factors.
Product Overview
The ThermoFlux – 7031 Thermal and Light Radiation apparatus provides a structured experimental platform for studying radiative heat transfer, a mode of heat transfer that, unlike conduction and convection, occurs across a vacuum via electromagnetic wave propagation. The unit is built around a horizontal track fitted with interchangeable heat radiation and light source ends. Either a heat radiation detector (radiometer with digital readout) or a light meter (lux meter) can be positioned along the track at measurable distances from the source, with scales mounted on both the front and back of the track for accurate distance measurement.Thermal and Light Radiation ThermoFlux – 7031, Technical Specifications

Experiments
- Inverse Square Law for Heat, intensity of radiation on a surface is inversely proportional to the square of the distance from the radiation source
- Stefan-Boltzmann Law, intensity of radiation varies as the fourth power of source temperature
- Kirchhoff’s Law, determination that the emissivity of a grey surface equals its absorptivity of radiation received from another surface at thermal equilibrium
- Lambert’s Law of Absorption, light passing through non-opaque matter is reduced in intensity in proportion to thickness and absorptivity of the material
- Determining the emissivity of radiating surfaces with different finishes: polished, grey, and matt black
- Area Factors, demonstrating that the exchange of radiant energy between surfaces depends on interconnecting geometry (view factor)
- Inverse Square Law for Light, illuminance of a surface is inversely proportional to the square of the distance from the light source
- Demonstrating how emissivity of radiating surfaces in close proximity affects surface temperature and heat exchanged
- Demonstrating that the exchange of radiant energy between surfaces is dependent on interconnecting geometry
Construction and Design
The Thermal and Light Radiation ThermoFlux – 7031 is constructed around a horizontal track fitted at one end with interchangeable heat radiation and light source assemblies. The heat radiation source is an electrically heated aluminium plate with matt black finish; the light source is a 60 W bulb configured for well-distributed output. Both sources have adjustable radiant power output. Distance scales are mounted on both the front and back of the track, enabling precise source-to-detector distance measurement throughout all Thermal and Light Radiation experiments. The radiometer and lux meter mount on clamped stands and are positionable at variable distances along the track. Three target plates, polished, grey, and matt black, each carry a bolt-on temperature sensor; their temperatures are displayed simultaneously on the control panel. An aperture plate (two vertically oriented metal plates) and a set of light filters complete the accessory range. All detector accessories clamp to stands for stable, repeatable positioning. Output from both the heat radiation detector and the lux meter is presented on dedicated digital readouts. The optional LabVIEW-based DAQ software interfaces with an included electronic sensor set for automated measurement and result calculation under Windows environments.

Q1. What radiation sources are included with the ThermoFlux – 7031?
The apparatus includes two sources: an electrically heated matt black aluminium plate as the thermal radiator, and a 60 W bulb as the light source. Both have adjustable radiant power output.
Q2. What are the three target plate types supplied, and how are their temperatures measured?
The three target plates are polished, grey, and matt black. Each carries a bolt-on temperature sensor; all three temperatures are displayed simultaneously on the control panel.
Q3. Which radiation laws can be verified using this Thermal and Light Radiation apparatus?
The unit supports experimental verification of the Inverse Square Law (heat and light), the Stefan-Boltzmann Law, Kirchhoff’s Law, Lambert’s Law of Absorption, and area factor (view factor) relationships.
Q4. How are source-to-detector distances measured on the ThermoFlux – 7031?
Distance scales are mounted on both the front and back of the horizontal track, enabling accurate and repeatable measurement of the distance between the radiation source and the detector at any position along the track.
