45 degree parallel heavy radiation tester | Solar Radiation Meters

This instrument is designed to measure the temperature change of a material sample under radiant heat. By comparing a test sample with a reference material, it provides quantitative data on thermal performance using the regression extrapolation method. It is widely used in laboratories for material science, protective equipment testing, and thermal performance evaluation.

Application

(1) Material Thermal Response Testing: Measures how different materials respond to radiant heat.

(2) Protective Equipment Evaluation: Assesses heat resistance and thermal behavior of protective fabrics and coatings.

(3) Laboratory Research & Development: Supports thermal characterization for product development.

(4) Quality Control: Provides quantitative data for evaluating the consistency of thermal performance across batches.

(5) Comparative Analysis: Enables testing against reference materials to benchmark thermal response.

Standards

The Solar Radiation Meter complies with the following international standards:

(1) ISO 9060:2018 – Solar radiation measurement instruments – Classification and requirements.

(2) ISO 17025 – General requirements for the competence of testing and calibration laboratories.

(3) ASTM E490 – Standard Solar Constant and Zero Air Mass Solar Spectral Irradiance Tables.

(4) IEC 60904 – Photovoltaic device measurement standards (applicable for thermal radiation characterization).

(5) EN 12975-2 – Solar thermal collectors – Test methods for thermal performance.

Product Features

(1) Sample Table with Reference Material: Accommodates both the test and reference samples (10 × 7 cm each).

(2) Fixed 45° Angle Setup: Ensures consistent and repeatable radiant heat exposure.

(3) Parallel Aluminum Black Plate Heater: Controlled radiant heat source with PID temperature control.

(4) Stable Heater Temperature: Maintains operating temperature at 90℃.

(5) Fixed Spacing: Sample-to-heater distance of 15 cm for standardized testing.

(6) Non-Contact Measurement: Uses radiation thermometer or thermal imaging system (8–13 μm detection wavelength).

(7) Regression Extrapolation Method: Converts temperature vs. time data into quantitative thermal properties.

(8) Controlled Chamber Conditions: Operating environment 20±1℃, 50±10% RH.

(9) Heater Storage Box: Ensures safe storage and handling of the heater unit.

(10) Calibration Included: Measuring table and heater calibrated for precise results.
