The tester requires a test ambient temperature of 15–25°C and a sample diameter larger than 58 mm. Calibration using the supplied high and low emissivity standard plates is necessary before each measurement session to maintain specified accuracy.
- Ambient Temperature Constraint: Ambient temperature must be maintained between 15°C and 25°C during testing.
- Sample Size Requirement: The sample under test must have a diameter greater than 58 mm.
- Calibration Requirement: Calibration using the high and low emissivity standard plates is required before each use.
- Power Supply Constraint: The tester must be powered by a DC12V adapter with a total power consumption of 20W.
- Heat Sink Usage: The included heat sink device must be attached to ensure temperature consistency between the test plate and the heat sink.
The measurement process requires initial calibration using the included high and low emissivity standard plates. After calibration, the sample is placed on the probe and the emissivity value is displayed on the LCD screen.

How does the Atomfair-HE-369 achieve ±1% measurement accuracy without an external heated heat sink?
The integrated LCD screen emissivity probe combines a controllable heater, single-chip microcomputer, and display, while the included heat sink device ensures thermal conductivity between the test plate and heat sink. This design maintains temperature consistency without a separate heating heat sink, delivering accuracy of ±1%, repeatability of ±0.01, and resolution of 0.01 per ASTM C1371-2004a (2010)e1.
What are the sample size and material limitations for using the Atomfair-HE-369 hemispherical emissivity tester?
Samples must be larger than 58 mm in diameter. The tester is specifically designed for coated glass, reflective thermal insulation coatings, camouflage coatings, and aerospace special coatings, but can measure any coating or plate meeting the size requirement within the emissivity range of 0.03–0.95. The test ambient temperature must be 15–25 °C.
What calibration and infrastructure are required for routine operation of the Atomfair-HE-369?
The device includes a high emissivity black standard plate and a low emissivity silver standard plate for calibration. It operates on a DC12V adapter at only 20W, making it suitable for field use without stable power. The total weight is under 1 kg, and it is stored in a portable hand case. No external heating heat sink is needed, but the heat sink device must be attached to ensure temperature consistency.
The Atomfair-HE-369 Hemispherical Emissivity Tester is a portable, ASTM C1371-compliant instrument delivering ±1% accuracy and ±0.01 repeatability for coated glass, thermal insulation coatings, and aerospace materials. Its integrated probe design and low 20W power consumption enable field use, while the included black and silver standard plates support calibration consistency.
Positive
- High precision and repeatability: Accuracy of ±1% with repeatability of ±0.01 and resolution of 0.01 ensures reliable, consistent emissivity measurements across coated glass, thermal insulation coatings, and aerospace materials, supporting quality control and R&D applications.
