Temperature Data Logger
Calibrate temperature data loggers for cold chain monitoring and temperature-controlled storage.
Standards
ITS-90, GxP (FDA 21 CFR Part 11), ISO/IEC 17025
Typical Interval
12 months
Uncertainty Range
±0.3–0.5°C
What Is Temperature Data Logger?
Temperature data loggers continuously record temperature in cold rooms, transport vehicles, and pharmaceutical or vaccine storage. Calibration verifies both temperature display accuracy and internal clock accuracy — the latter being critical for confirming the duration of any temperature excursions.
Applicable Standards
Primary standards: ITS-90, GxP (FDA 21 CFR Part 11), ISO/IEC 17025
ISO/IEC 17025-accredited laboratories must maintain an unbroken traceability chain from the calibration result back to NIMT (Thailand's national metrology institute) or another internationally recognised NMI.
Typical Measurement Uncertainty
Expanded uncertainty is typically ±0.3–0.5°C, depending on the measurement range, reference equipment used, and environmental conditions. The actual uncertainty will be stated on your calibration certificate.
Recommended Calibration Interval
A calibration interval of 12 months is generally recommended. The appropriate interval for your specific instrument depends on usage frequency, environmental exposure, and any applicable regulatory or customer requirements.
What Your Calibration Certificate Will Include
- Calibration results — instrument indication vs. reference value at each test point
- Error and expanded uncertainty (U) at k=2 (95% confidence level)
- Traceability chain to NIMT or a recognised NMI
- Environmental conditions during calibration (temperature, humidity)
- Calibration date, certificate number, and authorised signature

Frequently Asked Questions
Why is it important to calibrate a Temperature Data Logger?+
Temperature has a direct impact on chemical reactions, biological processes, and material properties. A Temperature Data Logger that drifts even 1°C can invalidate test results or damage products. Calibration anchors readings to ITS-90 or relevant standards (ITS-90, GxP (FDA 21 CFR Part 11), ISO/IEC 17025) within ±0.3–0.5°C.
How often should a Temperature Data Logger be calibrated?+
Most Temperature Data Loggers should be calibrated every 12 months under normal operating conditions. High-use environments, harsh conditions (vibration, temperature extremes), or regulatory requirements (FDA, GMP, ISO 17025) may necessitate more frequent calibration. Always follow the manufacturer's recommended interval as a baseline and consult your lab's quality plan.
What does a Temperature Data Logger calibration certificate show?+
A calibration certificate issued under ISO/IEC 17025 includes: the instrument identification (make, model, serial number), the reference standards used (with their own traceability chain), the measurement points tested, before/after correction values, the expanded measurement uncertainty (±0.3–0.5°C), the environmental conditions during calibration, the calibration date and next-due date, and the signature of the authorized calibration engineer. This certificate is the evidence required for audits and accreditation.
