4°C / −30°C refrigerators are widely used in biotechnology, pharmaceutical, medical, and research laboratories for cold and frozen storage of samples and reagents.
Over time, the actual chamber temperature may deviate from the displayed value or external monitoring devices, making periodic calibration essential for reliable storage conditions.

READY provides professional 4°C / −30°C refrigerator calibration services, including the following:

■ Temperature Recording (12 Hours)

• Recording begins after temperature stabilization

• Data logged every 5 minutes

• Total recording duration: 12 hours

• Measurements performed using calibrated reference thermometers

■ Display Temperature vs. Reference Comparison

• Comparison between refrigerator display temperature and reference thermometer readings

• Verification of accuracy and deviation assessment

■ External Data Logger Verification

• If an external temperature data logger is used

• Comparison between logger readings and reference thermometer values

• Validation of monitoring device accuracy

■ Application of Calibration Results

Calibration results may be used for equipment performance confirmation, internal quality management, or audit documentation.
Acceptance criteria should be defined according to the user’s SOPs and quality requirements.

READY also supports simultaneous calibration of multiple refrigerators, helping customers optimize scheduling and equipment management.
