SAFETY CONSIDERATIONS AND REQUIREMENTS
Follow basic safety precautions, including all national laws, regulations, and local ordinances in your
area regarding the use of this unit. If you have any questions about local requirements, please
contact the appropriate agencies.
SOPs
Because of the range of potential applications this unit can be used for, the operator or their
supervisors must draw up a site-specific standard operating procedure (SOP) covering each
application and associated safety guidelines. This SOP must be written and available to all operators
in a language they understand.
Intended Applications and Locations
These incubators are intended for professional, industrial, or educational BOD applications at a
constant temperature. The incubators are not designed for use in hazardous or household locations.
Power
Your unit and its recommended accessories are designed and tested to meet strict safety
requirements.
•The unit is designed to connect to a power source using the specific power cord type
shipped with the unit.
•Always plug the unit power cord into a protective earth grounded electrical outlet
conforming to national and local electrical codes. If the unit is not grounded properly, parts
such as knobs and controls can conduct electricity and cause serious injury.

INTRODUCTION
REFERENCE SENSOR DEVICE
Optional
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 Probe
Use a digital device with a wire thermocouple probe that can be introduced into the unit chamber
through the door 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 door
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.
