In modern industries, data loggers play a crucial role in monitoring, recording, and analyzing parameters such as temperature, pressure, humidity, voltage, current, and environmental conditions. Whether used in pharmaceutical manufacturing, food processing, energy plants, or research laboratories, data loggers provide the data integrity and insights needed for compliance, efficiency, and quality assurance.
However, with so many models and specifications available, selecting the right data logger for your process can be challenging. This guide explores the key factors to consider, important features to look for, and examples of professional-grade instruments supplied by Jansen Calibration for industrial and laboratory environments.
Using the wrong data logger can result in:
Inaccurate or incomplete data collection.
Non-compliance with industry standards such as FDA 21 CFR Part 11, ISO, or GMP.
Unreliable monitoring and increased process downtime.
Inefficiencies in energy or process control.
Conversely, choosing the right data logger ensures accurate, traceable, and continuous data acquisition, enhancing decision-making, regulatory compliance, and operational safety.
The first step is to determine which parameters you need to measure:
Temperature and Humidity Loggers – Ideal for pharmaceutical storage, HVAC systems, and cleanroom monitoring.
Pressure Loggers – Commonly used in process industries, hydraulics, and calibration laboratories.
Electrical Data Loggers – Designed for measuring current, voltage, and power in industrial applications.
Example Product:
✅ Keysight 34970A Data Acquisition/Data Logger Switch Unit – a versatile, multi-channel data acquisition system for voltage, temperature, and resistance logging.

In precision-driven environments like pharmaceutical or aerospace calibration, accuracy is critical. Look for loggers with:
High-resolution A/D converters (e.g., 24-bit).
Traceable calibration certificates.
Low uncertainty specifications.
These ensure your data meets regulatory and audit requirements.
Sampling speed and storage capacity are essential for reliable data recording:
Environmental monitoring – typically requires sampling every 10–30 minutes.
Fast dynamic processes – may demand millisecond-level sampling.
Sufficient memory prevents data loss during long-term monitoring and unattended operation.
Modern loggers support multiple communication and integration methods:
USB or Ethernet – for local data download.
Wireless/Bluetooth – for remote or field-based monitoring.
Cloud integration – for real-time data access and centralized control.
Example Product:
✅ Hioki LR8431-20 Memory HiLogger – a compact, portable, and high-speed data logger offering real-time waveform recording and advanced connectivity options.
If used in the field or harsh industrial environments, make sure your logger has:
Rugged construction and IP-rated protection (against dust and moisture).
Wide operating temperature range for outdoor or plant use.
Battery backup to prevent data loss during power interruptions.
For example, the Hioki LR8431-20 features a robust build designed for on-site reliability and durability.
For regulated industries, compliance is non-negotiable. Look for loggers that:
Meet FDA 21 CFR Part 11, GMP, or ISO 17025 standards.
Integrate with data analysis and reporting software for audit-ready documentation.
Support digital signatures, data encryption, and secure storage.
Many advanced instruments from Keysight Technologies and Hioki seamlessly connect to calibration systems for automated data integrity.
Data loggers are indispensable in multiple sectors:
Pharmaceutical Storage & Transport – Maintaining vaccine and drug integrity during shipping.
Energy Management – Monitoring load profiles in power systems and renewable energy plants.
Manufacturing Process Control – Ensuring consistent quality and minimizing waste.
Calibration Laboratories – Capturing precise data for equipment calibration and verification.
