Specification Verification Protocol & Decision Criteria

Critical hardware parameters to isolate in supplier documentation before evaluating thermal diagnostic suitability.

CRITERION 01

Native Sensor Array Dimensions

ความละเอียดเซนเซอร์แท้ (Native Microbolometer Resolution)

Distinguish between the true physical sensor grid and display-level interpolation. Budget devices frequently advertise screen pixel counts rather than the microbolometer matrix. A true 256x192 sensor yields four times the thermal data of an interpolated 160x120 array.

DOCUMENTATION CHECKVerify sensor resolution in the companion app specifications or sensor specsheet, not primary promotional titles.

CRITERION 02

Thermal Sensitivity & Noise (NETD)

ค่าความไวต่อความร้อน (NETD in Millikelvins)

Examine the Noise Equivalent Temperature Difference rating. Lower millikelvin figures represent superior thermal contrast for resolving minute temperature gradients across insulation defects or printed circuit boards.

THRESHOLD TARGETSub-50mK declared ratings indicate suitable sensitivity for building envelope auditing and fine thermal tracing.

CRITERION 03

Refresh Frequency & Radiometry

อัตราการรีเฟรชและการส่งออกข้อมูลความร้อน (Refresh Rate & Export)

Check whether frame rates operate at fluid diagnostic levels or standard restricted 9Hz caps. Confirm whether software outputs raw radiometric files (CSV or radiometric JPEG) allowing post-capture point-by-point temperature adjustments.

COMPATIBILITY NOTEStandard 9Hz units are sufficient for static thermal audits but introduce motion blur during rapid mechanical scanning.

DIAGNOSTIC PATHWAYS

Application-Driven Inspection Workflows

Targeting sensor configurations to distinct maintenance, electrical, and structural inspection disciplines.
