The reasons for temperature deviation in oven temperature tester measurements

Sensor aging or damage: Core components like thermocouples and thermal resistors experience performance degradation over time.
Internal circuit faults: Malfunctions in amplification circuits or AD conversion modules affect signal processing accuracy.
Insufficient device precision: The instrument’s accuracy grade fails to meet high-demand temperature testing scenarios.

Poor sensor contact with the measured object: Air gaps reduce heat transfer efficiency.

Damaged or poorly shielded test cables: External interference distorts measurement signals.

Excessive ambient temperature fluctuations: Operating conditions exceed the instrument’s specified range.
Uneven airflow or radiation in the furnace: Causes local temperature variations.
Unstable power supply: Affects the performance of internal electronic components.

Infrequent calibration: Measurement benchmarks drift over time without periodic adjustments.
Contamination on sensors or enclosures: Oil, dust, or debris impairs heat conduction and signal transmission.
Neglect of regular maintenance: Internal component dust accumulation or moisture leads to performance degradation.
