Accuracy and Response
Anritsu specifies ±2.5°C at 100°C. For AT-30 and AT-40, the listed tolerance is ±3.0°C at 400°C and ±3.8°C at 500°C. Use the specification applicable to your operating temperature.
The published 0.3-second response is the time to reach 99% of the measured temperature in boiling water or vapour. Air measurements can settle more slowly, depending on airflow and installation.
These probes are listed as non-repairable. The “S” durability notation denotes a special application for which Anritsu does not assign a durability evaluation.
Getting Useful Air Temperature Readings
- Position: place the sensing head in the air you need to measure, clear of walls and other surfaces.
- Airflow: allow the reading to settle at the actual measurement location.
- Surroundings: consider nearby heaters, hot surfaces and other sources of radiant heat.
- Connection: confirm the thermometer or logger accepts the selected thermocouple and plug.
