Accredited Data Logger Calibration Services
In data-driven industries, the integrity of your records is only as reliable as the calibration of your sensors. At DRS Technologies, we provide expert data logger calibration services to ensure your temperature, humidity, and pressure monitoring systems provide accurate, tamper-proof data. Our laboratory specializes in verifying both standalone and wireless logging systems, ensuring your facility meets the stringent requirements of FDA 21 CFR Part 11 and Global Good Manufacturing Practices (GMP).
Why Calibration is Vital for Cold Chain and Pharmaceutical Integrity
Data loggers are subject to “sensor drift” caused by battery fluctuations, environmental exposure, and electronic aging. In the pharmaceutical and food industries, even a 0.5°C deviation can lead to “temperature excursions” that invalidate entire batches of vaccines or perishable goods. Regular calibration by DRS Technologies provides the documented proof of accuracy required to pass audits, avoid costly product recalls, and maintain the safety of the global supply chain.
Our Technical Data Logger Calibration and Validation Process
The specialists at DRS Technologies follow a rigorous multi-point verification protocol to ensure your devices capture every data point with absolute precision:
-
Initial Diagnostic and Battery Check: We verify battery health and signal strength, as low power is a primary cause of clock drift and data loss in wireless loggers.
-
Environmental Chamber Stabilization: Loggers are placed in controlled chambers alongside NIST-traceable reference standards (PRTs or chilled mirror hygrometers) to acclimate to specific test points.
-
Multi-Point Accuracy Mapping: We test the device across its operational range—typically at low, ambient, and high-temperature points—to verify linearity and response time.
-
Time-Stamp and Memory Audit: We verify that the internal clock is synchronized with a master time source and that data is correctly stored and exported without corruption.
-
Certification and Audit Readiness: We issue a detailed calibration certificate that includes “As-Found” and “As-Left” data, measurement uncertainty, and a clear chain of NIST traceability.

Frequently Asked Questions Regarding Data Logger Calibration
How often should a data logger be calibrated?
The industry standard for data logger calibration is twelve months. However, for critical applications like vaccine storage (VFC program) or pharmaceutical manufacturing, some quality systems require a six-month interval to account for sensor drift and ensure continuous compliance with safety regulations.
Does the battery change affect the calibration of my data logger?
While most modern data loggers retain their calibration constants in non-volatile memory, a low battery can cause clock drift or electronic noise that affects measurement accuracy. DRS Technologies recommends checking calibration whenever a battery is replaced to ensure the device has not been reset or damaged.
What is the difference between “As-Found” and “As-Left” data?
“As-Found” data records the device’s accuracy exactly as it arrived at our lab, which is crucial for proving your historical records were accurate while the device was in use. “As-Left” data shows the accuracy after any necessary adjustments or repairs, ensuring the device is ready for future service.
