function, valid at 25C and 1m/s airflow)
Repeatability: ±0.1%
Resolution: 0.1%, 12bit
NOTE: Reconditioning of the probe may be necessary if
the probe is stored for a period of time in a harsh
environment (temperatures below 0°C or above 70°C or
exposure to chemical vapors, condensation, etc).
To recondition the probe refer to Appendix H.4
Temperature (T)
Accuracy/Range*:
Wand Probe: ±0.5°C for 5° to 45°C (±1°F for 41° to 113°F);
Up to ±1°C for 0° to 5°C and 45° to 70°C
Up to ±2°F for 32° to 41°F and 113° to 158°F)
Refer to chart in Appendix H
Industrial Probe:
±0.5°C for 5° to 45°C ( ±1°F for 41 to 113°F);
Up to ±1.5°C for -40° to 5°C and 45° to 124°C
Up to ±2.7°F for -40° to 41°F and 113° to 255°F)
Refer to chart in Appendix H
*Note: extended temperature range is for Industrial Probe
only, the iServer’s operating temperature is 0 to 60°C
Response Time: 5 to 30 seconds, tau 63% (response time depends on heat
capacity of and thermal resistance to sensor substrate)
