REGULATOR
The incubator must be connected to either a building CO2 gas supply system or a
supply cylinder (tank). A cylinder regulator is not included with the incubator, and
must be purchased separately. Please see the Accessories section on page 55 if
you wish to order one from Shel Lab.
RECORDING DATA PLATE INFORMATION
Locate the data plate inside the incubation chamber, on the top right corner of the chamber door.
The data plate contains the incubator model number and serial number. Enter this information
below for future reference.
Date Plate Information
REFERENCE SENSOR DEVICES
Reference sensor devices or a combined device must be purchased separately in order to perform
accuracy verifications or calibrations of the incubator temperature and CO2 displays.
Reference devices must be accurate to at least 0.1°C and 0.1% CO2. The devices should be
regularly calibrated, preferably by a third party. For best temperature results, use a digital device
with a wired-connected temperature sensing probe that can be placed in the incubation chamber
through the unit access port. For example: a wire thermocouple probe. For best CO2 accuracy, use
a calibrated digital gas analyzer with sample tubing that can be connected to the incubator external
CO2 sample port.
Reference readings that avoid chamber door openings during verification and calibration eliminate
subsequent waits for the chamber temperature and gas levels to re-stabilize before proceeding.
This also allows temperature and gas verifications or calibrations to be performed simultaneously.
Select probes suitable for the application temperature you will be calibrating or verifying the
incubator displays at.
Alcohol thermometers are insufficient for conducting accurate temperature verifications and
calibrations. Do not use a mercury thermometer. Never place a mercury thermometer in the
incubation chamber.
