Solar Radiation Meters

Product Introduction:

The purpose of this instrument is to measure the temperature change of the sample with radiant heat.

Arrange the sample and its reference material on the sample table, install it on the measuring table at an Angle of 45°, set a heating plate parallel to the measuring table, measure the surface temperature of the two samples with a radiation thermometer, etc., and measure by regression extrapolation method.

Scope of Application:

The purpose of this instrument is to measure the temperature change of the sample with radiant heat. This defines the core function: to quantify how a material's temperature changes when subjected to radiation from a heat source. Arrange the sample and its reference material on the sample table, install it on the measuring table at an Angle of 45°, set a heating plate parallel to the measuring table, measure the surface temperature of the two samples with a radiation thermometer, etc., and measure by regression extrapolation method. The test involves placing the material sample alongside a reference material (which has known thermal properties) on a holder set at a 45° angle. A heated plate, acting as the radiant heat source, is positioned parallel to this angled table at a fixed distance. A radiation thermometer (a non-contact device) is used to measure the surface temperature of both the sample and the reference over time as they are exposed to the radiant heat. The "regression extrapolation method" suggests a method of analyzing the temperature vs. time data to derive specific material properties related to thermal response. The instrument is used in laboratories for material science, protective equipment testing, and thermal performance evaluation.

Product Advantages:

Measures Material Response to Radiant Heat: Quantifies the temperature change of a sample when exposed to controlled radiant heat, providing data on its thermal behavior.

Controlled Radiant Heat Source: Utilizes a heated plate with controlled operating temperature and PID control for stable heat output.

Fixed Geometry: The specific 45° angle and fixed spacing ensure consistent and repeatable radiant heat exposure.

Allows Comparison to Reference: Testing a sample alongside a reference material enables comparative analysis of thermal performance.

Non-Contact Temperature Measurement: Uses a radiation thermometer, avoiding interference with the sample surface during measurement.

Provides Quantitative Data: Generates numerical temperature vs. time data for analysis.

Operates Under Controlled Environment: Designed for use in a measuring chamber with specified temperature and humidity conditions.

Product Features:

Sample table or holder designed to accommodate both a test sample and a reference material of a specific size (10 cm x 7 cm).

Mounting system for the sample table positioned at a 45° angle relative to the radiant heat source. The table is likely painted black (as indicated by "black painting" for the measuring table Angle) to standardize its thermal properties.

Parallel heating plate made of aluminum black plate, serving as the controlled radiant heat source.

Heater with a controlled operating temperature (90℃) managed by PID control for stability.

Fixed spacing between the sample station (measuring table) and the heater (15cm).

Requires an external radiation thermometer or thermal imaging system (as noted in the "Attention" section) to measure the surface temperature of the samples non-contact.

Designed to operate within a controlled measuring chamber environment with specified temperature (20$pm$1℃) and relative humidity (50$pm$10%RH).

Includes calibrated components for the measuring table and heater.

Uses a regression extrapolation method for data analysis.

Includes a heater storage box.
