Must be purchased separately
A reference sensor device is required for calibrating the unit temperature display.
Reference devices must meet the following standards:
•
Accurate to at least 0.1°C
The device should be regularly calibrated, preferably by a third party.
Temperature Probes
Use a digital device with wire thermocouple probes that can be introduced into the unit chamber
through the lid space. Select thermocouples suitable for the application temperature you will be
calibrating at.
Why Probes?
Reference readings taken outside the chamber using wire temperature probes avoid chamber lid
openings. Openings disrupt the chamber temperature. Each disruption requires
a minimum 1-hour wait
to allow the atmosphere to re-stabilize before continuing.
No Alcohol or Mercury Thermometers
Alcohol thermometers do not have sufficient accuracy to conduct accurate temperature calibrations.
Never place a mercury thermometer in the unit chamber.
Always use thermocouple probes.
